Airpump and airstones?

I have a Rena 300 air pump and I use it for one 4 inch air stone, and it powers my underground filter in my 35 gallon tank. I used to have a problem with it rattling against the stand, but I just folded a towel up and set the air pump on top of it inside the stand. As of now, it is still very reliable and quiet (3 years use).
 
i found that goldfish are really good cyclers. they produce alot of amonia compared to other fish and are usually pretty hardy. they say your not supposed to put them in with tropicals, but i always have. they dont seem to care too much about the water temp. also, if you throw a few feeders in there you would only be losing about 30 cents if one happened to die.:cool:
 
oh, also my goldfish and my cories LOVE to play in the bubbles, its so cute. i also have a gold mystery snail that loves to stick to the wall just above the bubbles. he sits ther for 1-2 hour sometimes. maybe its like a jaquzzi!:p
