I am having some trouble with my 10 gal. Someone suggested C-100. It is a Water purifier. It looks like gravel in a small net pouch.
Has anyone used this? It says to put them in your filter if possible. I have an over the side Whisper 5-15. Do I just put it in the small space behind the filter cartridge??
TIA
