Danner Pondmaster Coarse Foam Pad Replacement Filters #12195 (3 Packages)

I have a 40 gallon indoor koi pond (converted from the bottom part of an ornamental fountain). I put two of these in the bottom along with some gravel and rocks. The biological balance seems to be perfect as my water is crystal clear and my fish are feisty. I have a "Python" hose syphon/fill system. I vaccum once a week. The foam filters can be washed out a couple of times. If you are a bit squimish buy some refills they last depending on how man fish you have. I very pleased.the

Great value. Easy to clean and change. Perfect fit.

Clean tank, happy turtle 🐢
