180Bob

I'm sure he went way beyond that and built her a DIY Enductor.

Hi Friend: A couple of questions. What kind of container did your friend use? What was he container used for before getting the RO water? It doesn't take much residuals from a previous salt mix to kick up the TDS reading when you fill it up next time.

I have about 1 to 1 1/2 inches of argonite milk that has settled to the bottom of my tank as a sand bed so I don't see any reason to add any more.

g I also like the Oceanmotions. I have a Dart going to a 4-way as the closed loop on our 180.

I'm interested. I was also wondering why not send the evite out to all members? That way all members can choose which meetings to attend.

On our closed loop, I went with two 1 1/2" bulkheads. I then feed them into a 2' tee and then into our Dart. In your case I would switch to 2" as close to the feed through as practical.

Just remember that hybrids aren't the only high mileage engine option. In fact small diesels in some cases get better mileage and have low CO2 emissions. http://www.greencarcongress.com/2006/01/psa_peugeot_cit.html http://www.greencarcongress.com/2004/12/comparing_accor.html

Anyone looking for a very large skimmer? http://sandiego.craigslist.org/for/309776047.html

We are running dual 400W XM 10K's without supplementation. So far we are pretty happy with them.

I watched the whole video several weeks ago. I found it to be as anti-global warming biased as others have been in support of human caused global warming. I personally have no doubt that man has changed the environment. It started when he/she took his first breath and exhaled carbon dioxide. The real question is how much we are changing the environment, and what we should do about it. Should we do nothing, or should we all give up our cars and walk. My view is that the truth is somewhere between the viewpoints.

Look on the bright side. At least you know your cardinalfish is healthy and no longer hungry.

Jansen: Sorry I didn't see this until we got back home. If you still need some RO/DI let me know and you can come by and pick some up. Bob

She is just in a different time zone that the rest of us

All: We were wondering if anyone was interested in doing a pot-luck picnic after the Hatfield and Aquarium tours? We could meet at one of the local parks and just have a simple get together. One possibility would be the Yaquina Bay State Recreation Area, which is just across the bay from Hatfield and the aquarium (http://www.oregonstateparks.org/park_208.php. We would plan on bringing a small charcoal grill, coleman stove, and a big pot. We were thinking about stopping here http://www.oregonoyster.com picking up some oysters and steamers Is anyone else interested??>

GO DUCKS!!! Right into the Right into the Roaster

Actually W = ((Pw-Pa)(0.089 + 0.0782*V)/Y)*3600 Where W = Rate of evaporation at the surface of the water level (kg/h m2) Pw = Vapor pressure at saturation taken at the temperature of surface of water, in kPa Pa = Vapor pressure at the dew point according to the temperature of the ambient air of the room, in kPa V = Air velocity above at the surface of water, in m/s Y = Latent heat necessary according to the change of state of the water vapor at the temperature of surface of water, in kJ/kg And since the vapour pressure of water is approximately an exponential function of temperature the water loss is an exponential function of temperature. Also since the rate of evaporation is approximately proportional to the air velocity above the surface of the water. It should be much more effective to blow outside air directly at the water surface. If you don't use outside (by outside I mean outside of the hood or enclosed sump) then the partial pressure of the water in the air stream will approach the equilibrium vapor pressure at the tank temperature. In this case Pw will approach the value of Pa and W will approach zero.

I'll third that. His customer service is great. My only complaint is that his shop is one hour too far north.

All: Thanks for the comments. The pump that I'm actually planning on using is a Mag 2. It's the pump that seems to be recommended for the MR CR-6 Dual. I'm hoping that my reactor will be comparable to that one or the PM CR622D. I also did a quick calculation. The primary chamber of the reactor as it is presently designed has a volume of about 525 cubic inches or 2 1/4 gallons. Thus the MAG 2 should turn over the water 110 times per hour. This seems like it should keep it mixed pretty well. In any case I will design it so that I will be able to change out the pump easily in the future. I'll try to post pictures at the build moves forward. Here is how it stands at the moment.

We have a Sequence Dart plumbed through an Oceanmotions 4way going to eight points on the top of the 180. So far I like it quite a lot. bob

I used sketchup, which is free from google http://sketchup.google.com/download.html I found this article on AdvancedAquariast http://www.advancedaquarist.com/2007/3/aafeature2 This site also has some reefing examples that I found useful. http://www.suttonreef.co.uk/Sketchup.html Overall it seems like a useful program, especially considering the price.

I've been thinking about putting together a calcium reactor. My thoughts are to make it a dual chamber system that is basically a 1 foot square box with a divider down the middle. \[ATTACH]1056[/ATTACH] This way I don't have to worry about cutting circular flanges and I could make maximum usage of the footprint. What do people think?

Thanks Dchemist!

I agree with you. That is why I will be out on a coastal beach this Saturday cleaning up plastic bags, cups, deodorants etc. that others have seen fit to toss out.
