All I use is aqua clear filters. They work very well. The only break down in the last 3 yaers was a broken impeller from careless cleaning. I would recomend them to anyone and would not hesitate to buy another. And they are cheap.
A.C'S all the way baby ... but some will disagree and say that the emp has better bio filtration but I don't see how it's possible ... what make's AQUA CLEAR so great is media ,media , media... they come with small size BIO MAX media ...cut to fit filter pad's work well in it as well as bonded pad's to... it's a win win package brotha ....
