Dry rock is OK if it is reef rock

I only have to piece of base rock in this case and they came from my other tank which was setup for 3 years before moving into this tank.

I'd check your ro/di water, same thing happened to me where the filters were not doing their job and the Tds was really high.

Nope I've already checked the Ro/di changed the filters about a month ago, readings are find. 0. And the phosphates coming out of the water are 0.

wouldn't be that then, tap water usually contains
silicates, maybe your DI isn't working
