So I've made the wall, below, using coral skeletons, coral gravel, rocksalt & white cement.
It has set, but needs to cure in fresh water to let the rocksalt & lime from the cement leach out.
I'm using a TDS & a pH meter & comparing the readings against a control of dead coral also in tap water.
The plan is to soak the wall in seawater after the TDS reading has ceased rising, but I'm wondering if I should also soak the wall in a vinegar solution first?
Any opinions would be welcomed.
