    Playing with underwater camera case for Sony RX100 mark 2. Got some hits and misses on some goniopora selections. The ones I have now seems to be thriving. Some of my old acro that STN/RTN to a few polyps have grow back. Recently added a couple wild acro colonies, starting to color up a bit.

    So maybe I'm not understanding the problem correctly, but if you're Alk and calcium are high, all you have to do is take the reactor offline (just turn off CO2) and let you levels drop naturally. That'd be my recommendation. You are only a couple kh above acceptable levels. Also, as stated earlier, you cannot use a calcium reactor to raise one metric without raising the other. They will always raise and lower in conjunction with one another. Specifically, calcium is consumed at 20 ppm for each 2.8 kh of alkalinity. When you melt down coral skeletons that is the ratio that they will release. So raising your calcium even 20 parts will have a dramatic effect on alkalinity. Also, the idea that you can restrict the effluent to lower the pH, thereby increasing soluble calc and alk, is true. However, I don't know if it will increase the parameters output because you have also restricted how much effluent is actually entering your tank. Does that make sense? If you want to adjust the level of soluble calc and alk, I would adjust the CO2 output. Let your levels fall naturally and if you still want calcium a bit higher than where it currently sits in proportion with Alk, use some DIY calcium supplement. Sent from my SM-G955U using Tapatalk

    Harlequins are cool animals and will most likely take care of the Asterina problem but the problem is that they are obligate star eaters. They eat the tube feet off the stars but around 3% of this genus will also eat coral tissue. After they munch all the Asterinas and brittle stars, they will starve out, which is problematic. An ethical way to get around this might be to move them from one of your systems to another or cut a deal with two or three other PNWMAS members to help them keep their Asterina populations under control. It's a bit of a biosecurity risk but might be a better alternative. The first time I saw these sea stars eating SPS tissue in one of my exhibits, I decided to proactively manage these suckers by manually removing them. Each morning before the lights came on, there would be dozens on the inside of the acrylic. I used a fine-mesh net to harvest and remove them. It took months and short of natural controls, you can never get them all but it made a definite impact. After a while, I only saw them occasionally but kept up with it. I'll admit that this approach is a bit tedious but it does work and it rewards the OCD coralhead that lives in most of us. Asterinas are mostly photophobic. If you go the manual removal route, use that to your advantage.

    Meeting is in exactly 2 weeks! There will be some really great raffle prizes! We will be raffling off a 50 dollar Seahorse Aquarium ! This is a small shop in NE Portland and because there is less overhead you can find some amazing deals! Terry has done a great job in keeping the legend of Woody alive! Many of you knew Woody. Woody was the person who first helped us plumb our tank and they still have plumbing supplies to rival the bigger stores! He also stopped me from putting a chocolate chip star and a Grouper in my first 55 gallon tank and Terry carries on the same honesty! https://seahorse-nw.com/ https://m.facebook.com/SeahorseAquariumSupply/

    Pretty hard to see what it might be in that image. If you can get a better shot or three and post them, I may be able to provide a bit more information.

    Your clownfish might have a very short future. Just mentally prepare for him to disappear on you one day.

    I might give this a try. I expect it will be quite humbling to try to maintain a tank that size. People tend to think bigger is more difficult, when it is just the opposite.

    Looking at the betta falls tank today got me thinking. It could be fun to have a little contest to see who can set up the coolest pico tank on a budget. I've seen similar things done in other forums and it's always cool to see what people come up with. Here's what I'm thinking: -Water volume less than 5g -Budget of under 100$ for equipment. -Everybody has a month to gather equipment. Then three or so months to let the tanks grow in. -At the end, we put it up to vote and the crowd favorite wins. Anybody interested? Could be fun.

    Lexi is correct I was referring to the asterinas not the shrimp. Sorry my English and grammar and punctuation really suffer when I try to rapid fire post ...

    I think Kim is saying that the Asterinas were eating her coral, not the shrimp.

    Australia has the coolest corals from what I've heard. I'm planning a trip to the gbr early 2019 myself.

    This was what I did when I had a Harlequin pair. Not gonna lie, I felt bad for that poor little starfish cutting off their leg every week but I loved my Harlequins. They absolutely decimated my asterina stars and I agree with IntotheMystic that they can cause damage to coral. I usually make a habit of picking out any that I see at night. It does really help control the population but doesn't completely get rid of them. They ended up disappearing and I can only assume that they became dinner to one of the wrasses I had at the time.

    Sadly, those exhibits were taken down a few months ago due to the extensive remodel in the Visitor's Center. Lots of dust, noise and debris = bad for critters and acrylics alike! However, the long-term result was many fewer Asterinas and I never saw them eating coral tissue again. This approach removed them from 1 exhibit almost entirely (found 1 about every two months) and put the reproductive hurts on them in two other exhibits. They mostly reproduce by binary fission, which is why so many of them appear to be misshapen. The key is to keep up with the manual removal before the lights come on. I was harvesting them first thing in the morning five days a week. They like eating the algae and biofilm on the acrylic, where it is easiest to get to and they have the best grip. It will take a while but manual removal can work.

    Yea the plan was to remove and rehome them but I have never heard of them munching on coral. That's too bad about the brittle's too. Well, I guess that idea is out. I've attempted manual removal before but I felt like I was sticking my finger in the bursting dam. Hrm. I definitely was doing it mid-day though so perhaps your method will have better luck. I'll try that for a while and see how it works. I imagine that continually removing them allows a small void in the food chain to open up and allow something else to proliferate and out-compete. Is that the goal? Thank you for taking the time to respond. Your experience carries a lot of weight here and I appreciate you sharing. One last question, what was the long-term result in that exhibit? Are you still collecting or are you winning the war?

    Ya that’s what I’m thinking if I did a water change would probably be 15 gallons (it’s a 180), ive disconnected the CO2 (this will also give me a chance to get it filled). I don’t think my sps are that stressed a couple of my lps though I have noticed aren’t opening as wide as usual so I’m hoping it coming down naturally will make them happy.

    i would just take the reactor offline and let it drop naturally. One spike is enough stress, but a spike followed by a large drop b/c of a water change.. maybe a small water change? regular IO is about 8.5 dkh for what it is worth. Sent from my SM-G930V using Tapatalk

    In essence you are just shutting it down and that will work fine you will still continue to add all and ca until ur reactor chamber is cleared and ran it’s course

    I would not trust API kits. I would confirm like others have said with either other local reefers or LfS!! If you effluent has clogged up and slowed down I could see your alk numbers rising as the concentration changes with longer dwell time. Has anything else changed on the calcium reactor set up?

    I went with the Kef reference series. Love Kef. No tank as of now but there will be another. Wait for the daughter to get older so we can build the next one. Looking at old pics of mine and miss it.
