I have the API Filstar XP3 for my 75 gal
. Its rated up to 175 gal
, so it's more than adequate. Incredibly easy to prime, I really like that I can personalize the filtration media. Only negative is that it doesn't come with enough media. You'd need to add another carbon pack, pads (both coarse filtering and fine) and ceramic rings, bioballs or whatever you choose. Never once in the past 5 or 6 months I've had it has it leaked, and it's incredibly quiet.
