Do sea shells pose a threat to fresh water. I heard it helps raise Ph. Is that true
jsoong said:Depends on your water composition. Shells will dissolve into soft water & raise both pH & KH. But in hard water, where the KH is already high, it won't do much.
Otherwise, as long as the shells are clean (& has no bad bugs - might want to boil first), should be OK.
