Poly-Bio-Marine Filter PAD 4 X 8 (2 Pack)

This original polyfilter pad is not like the newer generic knock off as that is more like a filter pad .This removed junk which is in the water , invisible junk and far superior then the knock off .I do place it 2 days prior in container of water just not going to risk a change in PH but just being cautious I have used these for years love them and again do not confuse it with the new generic knock off .

If you have any problems with your fish tank. This product is very easy to use and understand.

Removed all traces of copper from my tank within a week.

I love this stuff!
