I didn't do a water change yesterday, but just did one now. I bought an adapter to hook the hose up to the sink so I had to test it out. Other than the one time the hose came apart from the attachment and water spurted everywhere, it worked great. I can now do a water change in about 15 minutes - no more buckets, woohoo!
I added dechlorinator for the whole tank and all the fish seem to be doing great - granted its only been about 30 minutes. One thing I did notice, the little filter wasn't throwing out any real water flow - took off the last extension and all the holes were clogged but a few. Got that straightened out now too. I bet that will help.
When I say "hanging near the top" I mean...kind of swimming slowly in place, mouths gasping for air. I'll try to take some photos this weekend - gotta break out my good camera.
Also, nope, not a teacher. If that question is because of the nickname, my name is Ed, my friends in high school came up with the special part. It stuck, I think its kind of funny. I'm actually a sales rep for science diet pet food, but thats another story.
Again thanks for all your help, you guys are great. I'm really enjoying this message board.
