    You would need to test the PH of the water first.....I would think..... will the epoxy not prolong the curing of the cement? If it were me I would rather wait to be sure first...

    Firstly what type of cement did you use? This can vary greatly on how the PH can change. I normally use poolcrete and color hardener for the reason that they don't influence the water quality that much. I would say soak the rock for a week in freshwater and then place it in the tank and set the skimmer on wet. It worked for my tank.

    Yes you should, if they don't have poolcrete you can ask for any cement they use to make cement pools, a pools ph is just that important as a tank's so any cement used in a pool will work for the rock.

    Ive used that white cement before and attached sps to it a week after it has hardened. The sps encrusted quickly so I guess you can assume there was that much leeching from it.

    if you covering it epoxy then theoretically the cement will never be in contact with the water, so you shouldnt see the pH swings etc.

    and thus could use it after a few days instead of the normal cement curing time

    My Input.....

    A lot of members on here Forum said that I need to cure my DIY Rock for a long time.
    I have 7500lt of water running thru my system for the last couple of weeks (months). 3 weeks after I put the DIY rock in, I added some freshwater fish to see if the water would be ok (freshwater for the curing process). Bare in mind I emptied the tank twice during the three weeks.

    The freshwater fish basically "burned" to death within the 1st day of being introduced. I am still running freshwater (zillionth time that I emptied all the water and re-filled) and am still too scared to change to saltwater as 2 "cheapish" freshwater fish I introduced last week also died. Still leaching too much....


    Btw, this is my 2 cents
