Marlin, how long has your rocks been siliconed to the back of your tank?

Thanks, this is giving me so many options!

I built my wall in the summer, so i had the tank sitting out on the covered porch and had the wall sitting in there. initial cure i did flat in my tub for a day so it had the strength to sit on an angle in the tank.

3 ft tall!!? thats an enormous tank. i believe mine is 24" tall 17" wide, and that section is just manageable. using cement gets heavy fast, so make sure you size your pieces correctly so you can lift them and secure them in the tank.

with regards to changing water, i bought some litmus paper and switched the water whenever it got over 10 early on. after a few days/ weeks, when it only ever got to 9, i dosed with white vinegar to bring it down and reduce the number of changes i was doing. You know you're done curing once you can leave it in the water for 4-7 days without significant pH changes. once i got there, i switched to salt water and monitored that for pH for 3 days, no changes, and then i added some LR to begin the seeding process. if you can, leave a Powerhead in the tank during the whole process.
