Odd question on old dry rock I have....

So I have some old dry rock from one of my older tanks.

I let the rock sit in a barrel outside for a year or longer. Now the barrel let some rain water get into the rock.

I am wondering if there is a way to salvage the rock? Would the below work or how would I go about it?

1. Bleach the rock to make sure nothing nasty on it is alive
2. Vinegar bath the rock to neutralize the bleach
3. I think there is some kind of acid bath to remove phosphates?
4. Cure the rock in a separate bin with a heater + power head and some saltwater?

Will this work or is the rock better off tossed?

Thanks

No need to toss it. Vinegar bath, a good scrubbing, then cure them in a bin with a heater/powerhead. Add some live rock from your tank if you can spare it, add a source of ammonia, then wait it out

I was under the impression I would need something to neutralize the phosphates in the rock since it will probably leech them after sitting in rain water for so long?

honestly i would not bother with it.. Toss it and buy new dry rock and a few lbs of live rock to seed it. It not worth what it can do with a year worth of crap it has been sitting in :eek:

my first salt water tank was in 1989 ( fresh water, 1960, my father own Tropical fish store) for some reason , always i use live Rocks (Fiji,Tonga etc.) now i run 99 % RRR, i like 100 % better, i control PO4, Nitrate way much easy. I guess live Rocks have time life, when got saturated of PO4, detritus, dead organic stuff, just leak back.

just rainwater or are you talking about leaves and bugs and stuff like that. If it was just a closed barrel that sprung a leak simply set up the rock like they do in any fish store and toss a polyfilter pad or 2 in there. put the first one in then wait and see what color it turns then go from there. I had 100+ lbs of some nice rock that had been exposed to COPPER for a month and a month of poly pads and water changes did it justice, results from the lab 0 copper.

just water
if you've got rocks that you like then go ahead and try what I did, put fresh saltwater in a bucket or container with a heater and something to push the water around then toss in a Polyfilter in there and see what color it changes. You'll notice after a week or 2 that regardless of the color of the pad there might be sand or dust like material at the bottom. Thats when you do 100% water change ad empty and wipe down the bin (we're talking 15-20 gallons depending on how you stack the rocks,maybe less) and go at it again and toss in a second pad. See if that changes color. after a total of a month you should be in business.
COST-$12 for 2 pads and half a cup of salt for however much water you go thru.

bleach it for overnight.
wash it thoughoutly
let them sit in the fresh water for a day
let it dry for a few days
let it sit (summerse) in the water for another day
dry it again
should be ready to use
I have done it every time in each of my last 4 setup.
Whenever I buy live rocks or dead rocks. I always bleach them before I put them to use. works every time and no issues

I am going to let them dry out in the sun, then stick them in a bin with a heater and saltwater to cycle.

I am glad I remembered the barrel as there is probably 100 pounds of rock in there.

rain water contains phosphates and bleach doesn't remove phosphate, acid bath will. from what i'v read.
