Chaeto's all gone.

pm's replied to.

Trimmed the Chaeto in my fuge about 3 months ago. Literally cut it in half, and it is overgrown again. I'll be trimming it out again this Saturday if anyone wants any. I won't be available until after 12:00, but whoever wants it can come and get it then. I'm still at work, so I'll check any PMs or posts when I get home. Chaeto will be first come first serve basis.

2nd clump is pending

One clump is gone, still have another bag of the stuff. It's about 1/4 of a gallon ziploc bag.

Trimming back the Chaeto today. If anyone wants it come pick it up Otherwise, just tossing it.

The lights on it were sold, but it still has the "What I believe to be a Eshopps PSK-75 venturi style protein skimmer powered by a Rio 600 pump."

LoL...the move will be no big deal. 250lbs of glass + a flight of stairs sucks!!!

hey douwant2ply, I teach high school physics and chemistry. Looks to be a heat transfer question. The formula you would want to use is m1*cp1*dT1 = m2*cp2*dT2 m1 = mass of the iron ball cp1 = specific heat capacity of the iron dT1 = change in temperature of the iron (initial temp - final temp) m2 = mass of water cp2 = specific heat capacity of water (4.186 J/g*C) dT2 = change in temp of water (final temp - initial temp) *note that the change in temp has to be positive for both the iron and water* because the iron and water will reach temperature equilibrium, they will have the same final temperature. I'll use T for that variable. Your equation then, should look like: (100 * 0.473)(125-T) = (200 * 4.186)(T-25) multiply it out and you should get 5912.5 - 47.3T = 837.2T - 20930 add like terms and get 26842.5 = 884.5T solve for T: T = 30.34 degrees Celsius

Hey Michael, My roommate and I actually just moved from a 75g to a 90g last weekend. I have a 48g rubbermaid tub that was used to hold our fish and some live rock during the move. You are welcome to use it. It's just holding some miscellaneous aquarium stuff at the moment. I live over in the Arboretum area. Just throw me a PM on here if you're interested.

I have a black and white and a true perc that seem to be hosting together in my frogspawn. Hopefully they start to spawn together too

Emerald Crabs are a great and reef-safe way to keep it in check. We had a bunch on our rocks when we finished cycling, put in 2 crabs and they had it cleared up in about a week. If you go with Emeralds though...look for ones on the smaller side. Fairly certain "Big Bertha" ate one of our chromis once the bubble algae was gone

Ya, water has a fairly unique property in that it takes quite a bit of energy to raise or lower its temperature, hence cold lake water in April, warm lake water in November.

Yes I do! My students are working on the exact same types of problems at the moment.

We are pretty much done with smashing stuff, until the egg drop competition in spring. Now we are lighting things on fire!!

I think a mandarin depends more on the amount of liverock you have, rather than the size of your tank. I've seen mandarins kept in a 75g do just fine. The guy keeping it had 125lbs of live rock in there, and the mandarin was in the tank for 1 year, happy, plump, healthy, and didn't eat frozen.

Nassarius may eat a few copepods here and there, but nothing that would affect the overall population of the tank. In my experience, they are more on the omnivore side rather than carnivore and stick to eating leftover food / detritus in my tank. Bumblebees on the other hand...I try to avoid, as I've read they are very carnivorous and if they can't find the fauna to eat in the sand bed, they go hunting on your rocks for pods.

All plants produce oxygen gas, but it, more often than not, dissolves into the water. It isn't released in large enough quantities at a time to actually "bubble" out of the plant.

Most likely it's a diatom bloom. Nothing major to worry about as most tanks will have them. This is especially true if you are just starting out and your tank is still cycling. How old is the tank?
