I was thinking hose the crap out of it to get the dirt out, boil it, then let it sit in the sun to bleach it.
Don't they use that to clean concrete?What about muriatic acid? How long have they been sitting out?
They do. It's also used in this hobby to clean rock. I use muriatic acid several times a year to regenerate my kati/ani unit. A little of the rock does dissolve when doing a muriatic acid bath, but it's a small price to pay when the rock has been sitting outside, absorbing ground water.Don't they use that to clean concrete?
And wouldn't that dissolve the calcium in the rock?
That's what I put in my tank. You got a good deal.I went to go turn in some chi child's at the local fish store for credit. They gave me $60 worth. I looked around the store and they had a sale on Carib sea Fiji pink live sand for $15 a bag. I bought four bags. There went all my store credit,... But hey, I essentially got it for free. )
