Hi dears ,
I have received an ATI test showing my RODI, where all results all elements are zero and, but the results have shown that the silicate is 1559 !! I changed my resin 3-4 months ago, so how has an experienced on this matter, thank

The first question is whether it is any concern. IMO, dosing silicate can be desirable (I regularly dosed it at levels far above what that water would supply for top off) and unless you have a problematic level of diatoms, I'd ignore the RO water silicate level.

What level do you see in your tank water?
 

Freshwater filter only or is it? Have you ever used an HOB filter on a saltwater tank?
