I’ve had a bunch of rock from KP and from a competitor in my tank for a few weeks now. There’s no comparison. The competitor’s stuff has some nice things on it, but is definitely going through “the uglies” in its cycle. Diatoms like mad and now hair algae have taken over that half of my tank. The stuff from KP has the non-nuisance algae that was already on it getting a bit thicker, but none of it seems to be the sort that wants to take over, and that seems to be preventing the hair from settling on it.
Also, the amount of life is amazing. I’ve seen so much stuff on the rocks already, and I know there’s more hiding in them since every time I look at the tank it seems I see something new.
Would definitely recommend anyone who wants some really awesome rock get from here.
