Thanks, our place is quite unique, we live on a hill and the pond is above the house
My plan is to try and get the rock showing through clear water. I suspect I will need to diy some kind of pond vac though to be able to clean the rock once in a while, a type that will pick collect silt and particles and not leaves etc.
I added 20kg gypsum this morning. Its been about 10 hours now and the water clarity has improoved from 8cm to about 13cm. Im not sure if it will continue to clean it more or not. If not I'll probably add another 20kg on Monday.
