Sorry Rachel, I am so new to this that sometimes you guys speak another language.
What is a spray bar? filter foam? where is the outlet?

I think I know where the outlet is... but I really am very new.
Actually, I bought an air pump for a 20 gallon tank (mine was only for 5) and I got a new hood with florescent bulb so the temperature isn't being pumped up. I took fishrpets advice and put a bubble stone in a hollow ornament (that I was worried about being hollow anyway) under the filter. All my problems with the the temp being too high, the current being too rough, and my fish being lethargic were solved. You guys really are helpful. I appreciate all the free tutoring and advice. I REALLY need to make a donation to Koko.
