Silica

[sbreefer]

I currently use a 7 stage RODI filter to make all of my water and keep it in a 160 gallon tank to use whenever. my TDS meter has read 000 for months and I am still getting high Silica in my tank. Any one have thoughts? what is the best way to remove it from WC water going into the tank? According to Aquamedic, my recent params are:
Aquarium - 4 of 4 *
03-05-2016 Ammonia (NH3-4) Good 0 0.000 - 0.050 mg/L
03-05-2016 Nitrite (NO2) Good 0.009 0.000 - 0.100 mg/L
03-05-2016 Phosphate (PO4) Good 0.05 0.000 - 0.250 mg/L
03-05-2016 Nitrate (NO3) Good 1.9 0.000 - 25.000 mg/L

Do you have a silicate absorption di?

I use bulk reef stuff. this will not pull out silica?

anyone?

Try "the filter guys" website. Jim sells silica(anion) resin by itself to be used in your ro/di in a separate chamber.. And it's actually very reasonable..

Doesn't list it on their website so I have no information on it. I'm using a Spectrapure system.

There are special cartridges for silicate removal. What is the silicate level in the tank, and how are you measuring it?
