I've bleached 2 40g pails of LR and let them sit out in the sun and rain for a couple of weeks now.
Today was acid dip day. I have about 50 pieces of live rock to do.
I bought some nitrile gloves, muriatic acid from Canadian Tire and had some baking soda on hand in case I splashed something on myself.
I put 10 liters of water and 1 liter of acid in an old salt pail and had a rubbermaid container full of tap water for rinsing.
It was actually a pretty tame procedure. The smaller rocks foamed a bit but didn't overflow the bucket. I left the rocks in the acid dip for 3 minutes each. I tried to put in about the same mass of rocks each time. I did about 10 batches per bucket of acid dip then I dumped it out and started with a new batch.
After 10 batches, the foaming was minimal so the PH had risen quite a bit and the solution was close to neutral.
For the larger rocks, 11 liters didn't cover them, so I did them at the end. I just added additional 10 liters of water plus 1 liter of acid. That covered the rocks, but also overflowed the bucket.
Definitely an outside project!
Tomorrow I hope to start drilling and stacking the live rock with some acrylic rods.
Gotta get this show on the road.
