i have 3 really old aquarium air pumps. can someone help me identify them?
I have the boxes and installation instructions, but i have no idea what size of tanks they can be used on! need a little bit of help from some fish people out there.
the first is a white box with a black and silver angelfish picture on
Im pretty sure the 1st (whisper 600) one is for tanks up to 75g
the 2nd one im not sure but im thinking its smaller
3rd.. 20-60g
Really it doesnt matter, it is just an air pump. its not going to hurt the fish
