  1. WTB potassium pomegranite

    What are you using it for?
  2. DIY Auto Top Help

    It happened. Be careful!! I went to my auto topoff smelling burnt plastic to find the pump melted from the inside-out . It was smelling of burnt plastic even though it was submerged in 6 inches of water. A relay is a better option.
  3. Activated Carbon

    Could you link the video? The craziest thing I find about activated carbon is that quite a lot of aquarist use it, but we still have nothing to test for. For either life-time of the carbon, or quantity to add.. It is has always been a rule of thumb and probably always will be. It's hilarious. Guess that is the beauty of the hobby. Sometimes you just know what's best. As goldenbasketreef said. Is there alternatives to activated carbon?
  4. Brian67 200 gallon starfire

    That just looks amazing. You are doing a good build. I have never seen a starfire tank in person. Now that the tank has rock in it, would you advise it to another person? It can be difficult to judge clarity with a camera.
  5. Bugs?

    Hey everyone! I might have a pest problem. To begin, there were two Acropora's in my tank that lasted a while and immediately died off. I know I had a bit of an alkalinity problem, but anything that was damaged came right back. After about 3 weeks of keeping the Acropora where they were (hoping they would come back), I decided to examine them up close. I found some bugs, that aren't on other pieces of coral. If I do a quick google search, they do somewhat look like other Acropora eating bugs. What should I do about them? There aren't any other Acropora in the tank right now, but some SPS, more LPS.
  6. Bugs?

    Wow! Thanks all for the quick reply. I have seen many larger copepods, but never this small. They have to be no more than 2 mm in length. I'll keep it in mind that AEFW tend to live on tissue. It was just odd to only find them on the plugs with acros.
  7. Ditto. Sounds like a good event.
  8. Italy!!!!

    If you have time, go check out the Murano Glass Factory. You'll like seeing the level of craftsmanship put into each individual hand crafted piece. It's pretty insane.
  9. Greenhouse Project [Pic Heavy]

    Hello Everyone! I have never properly introduced myself on the forum, but my name is Miles Taylor. I live in Corvallis, Oregon and am a graduate student in physical chemistry. Among the many things I enjoy, DIY of anytype is my favorite. Thus, I have decided to attempt to build a greenhouse for both saltwater, freshwater and a hydroponic garden. I have never grown coral outside, nor built a greenhouse, but hopefully we can talk about my struggles and triumphs. I could go and make a 3D image of what I want, but I already know what I want. Here is the overall idea: I would have coral on one side of the greenhouse and hydroponics on the other. Straight ahead would be a freshwater pond that goes from inside the greenhouse to outside. Limiting freezing and allowing certain plants to be inside for the whole year. The vats might end up being fruit trees, but we will see. I think it would be good to have a large sump with liverock in it. From the entrance My plan is to make leveled platforms for both the aquariums and the hydroponic setup. Allowing for gravity to feed water through piping if I needed, plus it allows for different plants to grow and have the necessary room. The greenhouse is going to be 9'x12' and about 9 feet at the peak. The location I chose is just outside of the fence to prevent any curious dogs from entering the pond: The nice part about this spot is it is going from east to west. It gets the full range of sun, without maybe 10° on either side. I was thinking about doing a pvc structure for a long time, but after my grandpa past there was a metal frame left behind that I was able to use. I think he would be happy it isn't just laying around in the desert. I drilled holes and began screwing the pieces together. The frame itself will be metal, with a polyethylene 6mil lining (I found out mil is not the same as millimeter...). The front and back will be a wood frame, that way I can build a door going in and out. I went and purchased some brick and concrete blocks for the foundation. I wanted it to be slightly off the ground, that way it wouldn't be all soggy during the winter. The advantage of raising it off the ground is that if the pond floods, it won't be in the greenhouse. My dad and grandpa have always dug into the ground a foot or so, that way temperature is better maintained throughout the entire year, but I decided not to. I plan tomorrow to lay down gravel with sand to make a flat base for the brick. The terrain itself is not flat, so I will have to terraform it. So far I've spent ~65 dollars, but there is still more to do. If you have advice, I am happy to listen. If you have questions, I am willing to answer. It will be an ongoing project, but it the structure itself should be done by January. P.s. I am getting paypal figured out for membership.
  10. Greenhouse Project [Pic Heavy]

    I might try some evaporative cooling techniques. They seem to work for larger greenhouses, but use tons of water. I should start collecting rain water now. Haha. I wouldn't be surprised if there are some commercial products like that. I know you can do it with an arduino, which is something I might try. Just need to wire together some relays and get a PAR meter. I only have a lumens one right now and they correlate, but are not a true correlation. Day: I lost track So I wanted to get my greenhouse done by January, but because there were some set-backs it is not quite there, but i do have some cool progress. My dad came by for the holidays and saw that the structure wasn't level and we tore it down. He was so right. We reused a lot of the material and I saved all the insulation for my new structure. I advise everyone to keep a level structure. It makes building so much easier and it really adds to the quality. Here is a picture after we took down the endwalls and built a new frame. He also said my structure was too heavy for what I wanted to do. My dad really helped me build a level structure, then I added the rear end wall. After making a level structure you can see how off the bricks were from being level. If I want an aquarium in there, the ground better be close to level...or else. I went and added some spring lock (I like to call it wiggle wire) to the structure. It is around the trim of the end walls and the base of the structure. I think it is a great product and would suggest it to any person building a greenhouse. I was able to easily install the plastic and remove it in a matter of seconds without ruining it. Here is what it looks like up close. The stuff is cheap and re-usable. I spent probably 9 dollars per 6ft of the stuff. With the channel and wiggle wire included. I went and added some plastic to the structure yesterday and installed my fan. I haven't cut the wiggle wire or plastic quite yet. The issue is with one person it is kind of hard to pull the plastic taught. So, I am going to wait to cut both of them when I find another person to help. I started doing the brick, but really felt like I could just do it later. I went and installed a fan to blow a layer of air between the folded over piece of plastic. I have a regulator around, which I will probably use because the fan is too strong. The fan is 12watts, which adds up to ~4.50 per month if I ran it. Not too bad for what it does. My favorite part of the whole system is I went and dug up a contraption I built during the summer. Originally it was going to be a weather station, but now it is going to be a greenhouse controller. Reloading all the firmware was worse than doing a software update on the international space station. It measures temperature, humidity, relative pressure, lumens and calculates heat index altitude. Then streams them live to my website: http://localdatacenter.org/ The arduino collects data, which goes to the raspberry pi and emits the data wirelessly to a web server every five minutes. The web server hosts the website and relays any incoming data. The case is a pelican case, which is semi-waterproof, but there is wires coming out which break the seal. it does some other neat stuff, but a lot of it still needs polishing. It measures lumens, rather than par, which is kind of a problem. **Note the current max/min values are a little off because it was in my room last night and was being turned off and on*** My next few goals: Lay out the brick and figure out what to do with the pond. I extended the pond probably another 6 ft and has a volume now of 300-500 gallons. I am not sure if I should add an opening into the greenhouse for the pond. I know I want to attempt to do some aquaponic/vertical grow towers inside the greenhouse and that would require piping from the pond. I just think it is going to let in too much cold. Edit: Due to unplugging and replugging in the power for the raspberry pi. Data values might be inconsistent with true values because it doesn't want to restart with the same ports etc.. Its a work in progress.
  11. Picked up a good sized coral package today

    Higher Thinking speaks the truth. Those corals look awesome!
  12. opinions on dosing

    Thanks. I was just curious what levels you were achieving with that type of dosing.
  13. opinions on dosing

    This is some good information. What is your normal Alk levels with dosing 4.5oz per day?
  14. Weekly Testing

    To allow us to compare, I am going to make a graph of what users answer to this question. What do you test in your saltwater aquarium weekly? I tried to find an embedded graph where users could click their answer, but I couldn't find it without leaving the forum. My say: Alkalinity, pH. I haven't had a need to test calcium or magnesium weekly, quite yet. The once a week water changes help with most issues. I don't really have to worry about phosphates or nitrates with the bio-load and only test them periodically.
  15. Activated Carbon

    I'll check it out. Thanks!
  16. the sand

    Personally, I have had troubles with fine sand. Whenever I use fine sand, I always notice detritus forming in low current locations and it bothers me. If I try to increase the current, all the sand gets tossed around. As a general rule of thumb, I think choose a sand for the type of corals you want, or the current they prefer.
  17. opinions on dosing

    What type of doser are you currently using? "Prestone Driveway Heat (de-icer)" I love it when people re-purpose common items for other chemistry purposes.
  18. Merry Christmas

    Merry. Merry Christmas.
  19. Corals are melting!!

    Just keep your head up and everything will work out. If you are afraid about the harshness of the new water, maybe ask a friend or local fish store for some cycled water. I bet you'll find someone who is willing to help out. It's the holidays. I can always bring 15 gallons up north if you need it. I only have three buckets, or it would be more. :P

    How are your corals doing?
  21. Greenhouse Project [Pic Heavy]

    I realized today that when I read a DIY, I read it to learn something. Thus, I am going to try to add more facts or things I learned in the process of this build. I have been building more, but not enough to post pictures. It has been raining a lot. I didn't know anything about R values before either, but it is a pretty easy concept. A R value is the ability of an object to prevent heat transfer. Different things, have different R values. I was strolling down the insulation aisle in home depot and they are all over. Values ranging from 0.9 all the way up to ~30 for foam. It is pretty interesting how someone put in the work to go and measure thermal resistance for all types of objects. Also, I encountered so much frustration today. I don't know what kept me building. GRRR!!! For all those that are going to build something, make sure the frame is aligned from the beginning. Due to the frame being uneven, every single board has to be uneven. It is a systemic problem that I have learned about the hard hard way. Measure twice, cut once. *sigh* Thanks for the support. It helps. I think it would help if I added maybe two 55 gallon barrels that were painted black. Even 5 degrees or so. Many greenhouses online do something of the sort, but I am unsure about how efficient it is. The funny thing was at home depot I had a conversation with a worker about using the canned spray foam as insulation. We thought that a single can may have done 15sq ft at 6 inches deep. So, I went and bought a few cans. To find out, it doesn't do that much. It maybe did 4sq ft at 3 inches deep. Now I just use it to seal any large cracks in the frame. It works really well for that. I did go with a polystyrene insulation. The R value is 13 for the thickness I am using, and it was cheaper than fiberglass insulation. The advantage of the polystyrene was that it is relatively waterproof. If the fiberglass got wet from either the rain or humidity, it wouldn't be as effective. Wow! 200 par? That is amazing. May I ask what type of corals you have in your greenhouse? That really is a good idea. Although, I would have to hardline it below the house to the garage, and I would have to do it when the roommates aren't around. Another problem is, my roommates don't really want to pay to heat the house during the winter, or cool it during the summer.....just another thing I have to battle. Water volume seems to make sense, but I need to figure out a way to effectively use it. After adding the plywood to the back wall, and not being able to see the pond's outside portion. I might throw some type of thermal covering over the outside it when winter comes. That way there is less transfer to the outside world, and it probably would stay somewhat warmer. I am really trying to make the end plates both water proof and air tight. My dream is for it to be so sealed, that there is a pressure difference between the inside and outside. :P It's ok to dream, right? I think spit balling is a good idea. I appreciate it.
  22. Corals are melting!!

    Some of those pictures remind me of when a coral is in the sand bed for too long. You had said that there was a bit of a sandstorm, which may have caused some hydrogen sulfide to be kicked up. Especially, with sand beds that don't get turned over too often. I was curious about what hydrogen sulfide does to corals, and came along to this paper: http://www.pnas.org/content/109/24/E1558 There is some interesting stuff in there, but I guess a common thing with sediments, corals and hydrogen sulfide is there is somewhat of a cascade. As some tissue dies on the coral from being in the sediment, it lowers surrounding pH, causing more hydrogen sulfide to be produced by microbes. Maybe do a good sized water change, but in my opinion it looks like some sediment might have hurt them.
  23. Looking for local Portland programmers

    "Other than PHP" :P That is funny. I know more people that don't do PHP, than do. What languages are you dealing with?
  24. Tank Drilling

    I didn't know there was a possibility of "too thin" of glass. I thought it would make it easier. what is minimum thickness? I was going to attempt to drill some of my own tanks and I am curious.
