Hi there,

I am just cleaning some gravel that I just got and there is lots of snail shells in there. Will they change pH or not? if so, they will be placed in my soon to be African tank, but if not they will stay with the angels.

Also, what would kina shells do?

Cheers,

George

I would think the snail shells would but not sure about the kina. I Googled it but am none the wiser :-?

OK thanks anyway

Good question! :lol:

They won't change the pH (not measureably, anyway), but they will act as a buffer against the pH dropping.

scallop shells and similar raise PH as they dissolve.

Yea i have some for my African tank What about paua shells do you know?? 8)

Im not sure sorry I just remember being told scallop shells are the best!
