DIY Rock (oystercrete) curing??

[Skimmerking]

test for Phosphates and then run some Phosban through a reactor

if you did it in such a small ratio of cement.
i would break a rock in half and place it back in water and again test for ph.
of course after testing it for Phosphates.
good luck,hope all goes good.

Ya I will test for phosphates, and I have tried breaking a rock and it did not change the ph so... I will give it one more week and then see how things go. It is going into its own tank and I am going to seed it...so I am not worried about it ruining a established system, thanks for the advice

when I did a bunch ages ago, I found that after the PH stabilized out in fresh water it would spike again in salt.
I would add some salt to the water (if you want to be cheap, just use rock salt) and watch the PH again. Mine spike up to 11 after adding in the salt, and took about 2-3 weeks to come down again.

Come to think of it, years ago i had the same problem as Wolf_bluejay.

I did have them in salt about two weeks ago for about a week and no spike so I went back to freshwater curing. I am pretty sure they are cured because I have 2 batches curing in two seperate tanks and they have both been holding at 8 for weeks now....I am going to soak for one more week and start the tank up I think...see how it goes?

Sounds like you are ready to go. Seeding it in its own tank is going to be redundant but definatly a good idea!
