After drying for 2 days, I re-assemble them into the tank, with LOT of silicon glue to attach to the back of the tank.
Now, fill up the tank with water and change it daily. The cement has very high PH, and you need to change water till the PH is normal.
OK, that was about 2 weeks ago, and the PH is still sky high!!! Others who have worked with cement in tanks say that we need to wait for up to 1 or 2 months!!!!
For me, the wait will be worth it!!
