What do you think about curing homemade rock in tank?

[Anonymous]

Howdy folks. I have been making rock for the past few days and stuff, but the other night I made a piece specifically for a spot which will be under my rockwork in my own tank. It's about 12-15 pounds or so. Think there will be any noticeable pH problems if I cure it in my tank (combined capacity approx 850 gallons).

Thanks

If you just "made" your own rock, why would it need to cure?? What is on it that would "die off"??

It's home made rock, thus made of portland cement and oyster shell. I cure the rest of it in a 300 gallon in freshwater which I change out ever other day.

By cure I do not mean any die off on the rock, I mean curing it to make sure the cement doesn't cause the pH to get too high. Just like when one makes cement frag plugs they cure them in the back of their toilet or something before they add it to their tank.

I wouldn't put it in your tank until it is fully cured, it is not worth the risk of shooting your PH too high.

Someone I spoke with said they cured theirs by tossing it into a freshwater creek for about a month, then go get it and rock n roll. I thought that was an excellent idea.

850 gallons is a lot of water... you're probably ok. I would cure it for a week in FW just to be on the safe side.

I like the idea where u cure it in your toilet tank better (on back of the commode)> Much less chance of outside contaminates. plenty of water changes and automatically done after every flush.

don't know exactly what the ceement produces,or how large a system would be needed to not be affected, but if you want to play it safe-why not keep it soaking in fresh water, and periodically test the ph to see when curing is done?

would it cure faster in air?

Here's some pics. Not exactly toilet tank material.
