A product which, IMO, everyone should be using: Sponge Power

Oh those darling little angels!

A cure for hydroids?

I use Sponge Power and I like it so far. I've seen growth in a yellow sponge in the last two weeks. It went from nothing to about the size of a quarter. I will probably keep dosing.

FWIW,

My pair of African Flamebacks eat hydroids like it is going out of style
