Andrew Clark –
The filter foams fit perfectly into my Oase BioSmart filter. I’ve used the red and blue ones together and noticed a clear improvement in water clarity after a week. Easy to install and the fine filter helps catch small debris.
Tracey Watson –
I changed one red and one blue foam last month. The pond water looks cleaner now. I didn’t have to replace all at once, which is good for maintaining the bacteria.
Jacob Watson –
The green foam caught fine particles that were previously slipping through. Combined with the blue, it works well in the filtration stages. No leaks or issues during use.
