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

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.

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?
