I would recommemd not usimg cement do to leeching. You could dowl the pieces together using plastic rod. I still feel like epoxy is your best option. Ive heard of some using great stuff foam omce cured but thats purely hearsay... what issues did you have with the epoxy?

Hydraulic cement. It is safe to use on cisterns that store potable water.

i see witch one would u recommend i heard good things of hydraulic cement if so can i use home depot and put it back in the tank after 24 hours ?

The brand I have is DAP. It sets in 2-5 minutes even underwater. I haven't had it in my reef tank for long, but I have used it in freshwater for years and in much bigger quantities. Be aware that it can temporarily raise your PH. I've never had an issue with DAP brand, but it's something you would want to keep an eye on.

Oh, it's also dark grey so pretty obvious unless you hide it.

Home Depot and Lowes should carry hydraulic cement. Just ask and make sure that the product uses Type III cement.

I used sanded grout to build this background.

I would not suggest just dropping it back in the tank right away. I let it set submerged under tap water for about 4 weeks before it stopped or at least became a manageable level of ph increase.

i used this and within 6 months it started crumbling apart, loosing parts of my rock work.

marco rocks makes a specific marine cement, that would be what i would use if i had to do it over again.
