I've never had a tank big enough to require aeration but now i'm getting a 25 gal I would like to know whats involved. I'm guessing you have to buy a air pump of some kind and connect it via tubing to a bubble wall or something like that. Do you have to buy this stuff seperately or do you get them in a kit together? and how many watts would my air pump have to be for a 25 gal tank. I'm new with these things so any information would be helpful.

For a 25 gal, you basically buy an air pump (with one outlet should be enough) and enough airline tubing and whatever u want to connect it at the end with (airstone, bubblestrip, bubble disc, ornament, etc etc). Usually they come separately, as you know we fish-people like to chop'n'change & modify & whatnot.

great, thanks. Any suggestions as to what would be best? i was thinking a bubblestrip along the back.

I have a bubble wall that is bendable so I can make it any shape I want ,and I love it ,gives me more options when I'm redecorating my tank
