High Silicon Level

[Smcevoy]

So I’ve had an icp test done and my silicon levels are through the roof at 625. I’ve read Randy’s comments on others about it not being an issue but really curious on my levels and how to remove it. I have a 7 stage RODI system putting out zero tds

Do not panic at all - especially if you not have problems with diatoms - below you can see my Si levels during the years - peak at around 18 000 µg/L without any serve problems with living things. In my case - Sera Siporax in anaerobic conditions was the rot of the problem. It is know that other filter media of the same type can create this. It is probably not your RoDi that is the cause - it is likely processes in your aquarium. GFO will lower the Si too but you are low in PO4 - do not use that. Just observe and wait for the next ICP test.

I'm not even sure it is silicate for these high levels and not something else. such as fine particles of SiO2, or maybe even diatoms themselves getting into the ICP.

Fine particles of SiO2 - maybe because I got the widows covered of a thin layer that I think was SiO2. However - IMO - diatoms is unlikely in this case - no problem with diatoms in the water or even on the sand.
