what I want to know is what is the treatment after the rock has soaked in acid ot get it ready for the tank

Just some fresh and/or salt water rinses is all it takes to remove any excess acid.

Or add a teaspoon or two of draino drain cleaning crystals to your bucket to neutralize the acid in your water and rinse. It takes a lot of 7.0 pH water to neutrlize a lot of acid (very low pH near pH zero) in water. Does not take much pH 14 water to netralize acid in water. Water is cheap though, but it will take a lot more plain water as you are trying to rinse away versus neutralize. A combination of both is much easier.

Thanks guys for the help...

So is there any test that I could do to verify that all the acid has been neutralize?

Rightnow the rock has been soaking (cycling) for about a month and has gone thru a complete cycle. I was hoping to start puttng the rock back into the tanks this weekend.

So far I'm very happy with the results from the acid soak, the rock appears to be very clean (pest free) I guess only time will tell

Thanks again for all the input

pH measurement is all it takes.

Im going to bleach my rock in the morning.would it be better to boil it or bleach it?my aiptasia/bubble algea outbrake is calling for one of these treatments
how long do i boil the rock?im going to use a turkey deep frier,so ill be out side.plus people say it smells like boiling crab leg.....I LOVE COOKING CRAB,THE BEST.who does'nt like crab legs.
Anyway,how long do i let them dry out and when do i put then back in the DT?Do i need to do a cycle?
Now if i bleach it how long do i let it soak?how long is the dry time?cycle?when can it go back in the tank?
Thanx guys/gals,ive done alot of reading to get rid of my issues and at this point i want to start over as far as the LR is concerned.
No big deal,now i can stop being lazy and clean some things up and frag all my softy for future sales..

Bleaching will remove the dead organisms, boiling will not. Boiling will not have any concerns about residual bleach. So there is a trade off, but I'd pick bleach, myself.

Timing will depend on how much organic crud is on it, but overnight in 10% bleach may be adequate.

If all the organics are off, it will be like dead base rock in terms of cycling.

Drying is slow, but can be accelerated by rinsing and/or dechlorination treatment.

How do you plan to "cook" it? You may be able to replace that step with an acid bath.

I don't really have a detailed recipe/plan for this, but a number of folks have used it.

If you are convinced you want to kill everything on it, I'd first soak it in 10% bleach/90% tap water (or RO/DI) overnight. The rock will probably look clean, but if it has apparent organic crud on it, I'd brush it off and then I'd repeat with fresh bleach.

Then rinse well in tap or RO/DI and we'll get to acid rinsing if you want to try that.

No acid in the bleach (that's dangerous). The acid is a separate step to remove any phosphate deposits on the live rock by dissolving away the outer layer of the rock.

hi all, wanted to give an update at least a week after I soaked my LOR in bleach.

- I soaked about 150lbs in 30 gallons of water and 3 gallons of clorox bleach (10:1 ratio).

- It seemed like after a few days it lost its power. this was confirmed by the experts in the above posts. So I decided to run it through the process one more time.

- So last night (over a week after first starting) I took all the LR out and emptied the tub. I was surprised to find the water was very murky/dirty and a ton of residue at the bottom. I think this was sand-like material. But the water was defintiely dirty.

- As I examined the rock some of it looked very white, some had pinkish dots on it. and then others still brownish. This surprised me too. I expected to see all white rock. It seemed like the LR on the bottom of the tub didn't get as clean as the LR at the top.

Anyway, last night I emptied it all out, filled it up with fresh RODI and 3 more gallons of bleach. I'm expecting to see a difference when I check it tonight.

Oh, and if I can find some muriatic acid, I think I'll run it thought that one time as well.

doug - you sometimes can. i used to but cant find it anymore. i just went to my local swimming pool suppply store and found it there. it used to be called muriatic acid but i think its correctly called hydrochloric acid. they had it stored in the back b/c its pretty dangerous to handle.

i'm going to dose it in the next day or so. figure a 1:10 ratio with water? let it go for 24 hours?

do you still need to decholinate the rock,or will the acid do that too?
