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

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.

No complaints

Much love for API continuing to sell these sponge pads by PPI. It can be extremely hard to find sponges of reliably different PPI for implementing in multi-stage filtration. This is easily cut to size for other filters.

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 :-(

I actually used this foam for a different application. My old Big Green carpet shampoo machine needed a new foam insert in the vacuum intake manifold. The manufacturer no longer makes parts for my machine so I purchased this foam, cut out a circular piece, and cha-ching - I was in business again. This foam was identical to the original in terms of density.

When I first bought my filtration system I didn't read on the package that this product needed to be changed every 3 months. I'm too embarrassed to say how long before I finally realized that I was WELL OVERDUE!!! lol Anywho very good product and by all means PLEASE READ THE INSTRUCTIONS UNLIKE THIS KNUCKLEHEAD that didn't :)

I like the filter..They are easy to change and you make it easier to find.. I couldn't find it in the store's and now I don't have to worry about where to find them.

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.[...]
