your salinity seems a bit low, what is your alk?, diatoms thrive on silicates, did you use any base rock that might be leaching silicates?

I just got a new Hanna Alk tester, I will test today and let you know after I test. Sorry I don't know the term base rock. If base rock is dry rock to start, then yes I did and yes it is probably producing silicates.

Base rock is rock used at the bottom of the tank that the live rock sits on, it's not usually live rock and might contain silica.
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

Ro/Di water tests are good.
