RO,DI question!!

[Zbass]

I have a 4 stage RODI with a water saver attachment. just got my ICP back and my silicates are high. does this mean my di resin needs to be changed or I need to add a extra stage of resin?

What is the level of silicates? Is your resin cartridge depleted? does it look yellow?

maybe. still a lot of black left in there? silicates 442. everything else was clean

Yep, i would change that with a fresh one. What are your phosphates in your tank currently, very high or no?

nope. everything is low actually which I was suprised. BUT I just got a algae bloom in my 15 gallon so wondered if that's why

To counter the silicate issue if your PO4 is reading low but you have a lot of algae, you can run rowaphos in a reactor. But ya, at least you know the source! def replace the resin cartridge, may have to do that often. I have a 7 stage with 3 di's and the test come back zero everytime, but my city water is pretty clean, that's not the case for everyone unfortunately.

probably smart to replace sediment filter with it?
