Cement from MacroRock - E-Marco-400

[Bao]

Hello everyone,


I used about 10 Lbs of this cement to glue together some rocks for my 75 gallons tank. I plan on removing half of the established rocks in my tank and replace them with all of those rocks newly glued together by the cements. Anyway I am afraid that if I put them in there, there will be a PH spike?
Have anyone use those cements before?
How long do you have to wait for them to cured?
Did you have to cook (put them in fresh RODI water) them in fresh RODI water so it would neutralize any bad chemicals released by the cements?

Any comments or suggestions are appreciated.

Thanks.

No spikes at all... I used it in my tank.. I cemented my rocks and 3 hours later filled it with water and corals... It's potable safe..;)
