Water chemistry help

[SpencerT82]

I just sent out an icp test and revived my results. Says I have way too much silicates which I believe is true because my diatoms are going crazy. It’s not a new new tank it’s about 1 year old but do you think it’s because I added a ton of ceramic bio media into the sump for refugium? Or is there another cause? And how do I remove it? It also says I have too much iron how do I remove that? And says I have to much vanadium how do I remove that?

Tap water can be a major source of silicate, or RO/di with tds of the effluent above 0 ppm.

What are the iron and vanadium values? They may be fine. Icp companies have a hair trigger to recommend changes.

Any metal parts in the water?

The vanadium is 12.00 µg/l and the iron is 6.00 µg/l. No metal parts in tank except my flipper magnetic algae scrapper. Also for your other comment i use a 4 stage brs rodi filter with 0 tds only never put anything else in.

The iron is no concern. Red Sea actually recommends far higher, although I think that is only so their kit can detect it.

The vanadium is also not likely an issue.
