Coral pro silicate levels

[Aquariumaddictuk]

Afternoon all.

I'm struggling with diatoms on sand & to a lesser extent, the glass.

Corals are all doing great & levels are nice & stable.
Tank is 4 months old.
It's over the other "ugly stage" issues.
RODI is showing 0 TDS.

Parameters are as follows:
Kh 11
pH 8.3
Cal 475
Mag 1400
Nitrate 20
Phos .3

Has anyone experienced issue with silicate in coral pro salt?

Since I have started using coral pro, I have had major diatom breakouts as well. I'm not sure if it is because of coral pro salt, or just a coincidence, as my tank is only about 4 months old.
