This is probably an obvious question but...

Are your fish have breathing troubles. Unless it looks like they are labouring for breath they are getting plenty of oxygen. Other wise a small pump with an air stone will help but it also lead to faster evaporation.
 
sometimes it looks like sharky is breathin a lil rough. I dont have an HOT filter for it, just canister. Thinkin of gettin a bigger air pump tho. I am definitly aware of the evap situation. I had my pump give out last night and water backed up down the air tube, flooded the pump out and fried that sucka, so its time for a new one. Guess u could call it an automatic water change, seeing as how i woke up to a 51 gallon tank.. ehhe... At least the sucker is clear for a change. Bout to put in the micron filter and polish the water up :)

What about Marine plants.. I havent seen n e in the LFS's. I have a few peices of LR in a 10 gallon that have small plants on em, i was thinkin since there isnt n e fish in it, just a few crabs, pullin that and puttin it in the 55. Good/Bad idea? Just let it cycle for a few weeks, then slowly add the rock back
