API FILSTAR XP FILTRATION FOAM 20 PPI Aquarium Canister Filter Filtration Pads 2-Count (723A)

We have a 55 Gal tank with a Rena XP2 filter unit. From bottom to top we use 2-20s then 2 30s, in the next basket it's the activated charcoal then the bio chem stars with two Micro filtration pads to finish it off. Works extremely well. Change the filters ever 2-3 months and have never had any problems even though we tend to overfeed :-(

Parts as advertised. Arrived quickly.

What I needed

I'm going to copy this review for several of their products, since they all work together and I'm equally pleased with all of them. I use these filters with a filstar xp3 filter to keep an approximately 100 gallon pond clean. There are 5 turtles, lots of fish (since the turtles would rather not work for their food), a rather large plecostomus and the occasional frog in the pond. With some assistance from the plecostomus, I've never had an issue keeping the water clear; even in the summer when I have to add water to it at least every other day. I use the ammonia remove pouch, carbon pouch, bio chem-zorb pouch, bio chem-stars and the 20 and 30 ppi filters. Anything that can handle that many turtles definitely deserves 5 stars.

I would find that a higher number of pore per inch would clog too fast and not provide adequate filtration. This sponge does the job perfectly and does not need to be changed. Will grow beneficial bacteria in the filter causing crystal clear aquarium water. Check out my channel for results. [...]
