The astronomically high silicon levels is from when I was dosing water glass (silicates) into the display to try to induce diatom bloom. I didn't test for it when dosing. Definitely overdosed.
In my previous ICP a month ago, it was 13 ppm. Now, it's down to 9 ppm. So I'm just going to let it fall naturally over next 2-3 months. Just sucks that Hanna phosphates tester not accurate when silicates are higher than 2ppm.
I really need to do a water change to get everything back to normal.
