before i make the trip to home depot or lowes, can anyone tell me if they have slate rock (doesn't matter if its aqaurium safe cause i can seal it with sealant/epoxy so dont lecture me about it plz.
you know the flat kind of rock used for ponds and stuff?
I got back from the world of wet pets (great store, ok customer service)
got a few rocks, just to start, gonna get silicone later and maore rocks and gravel
i came home to find than my peice of shale was very flaky on the sides when brushed with a tooth brush (duh duh dur). this isn;t good for my tank, but can i still put it in or will that cause problems. also, i want to break up the big rock pieces to smallish, ping pong ball width round pieces. Can i use a rock tumbler, if not, can i use sand paper, or a drummel or something... or am i screwed?
