Diatoms or Dino and random silicate level

[Randy Holmes-Farley Verified Community Expert]

Whille your still floating around randy, I've been testing water change rodi and after mixed for silicate and seems good. Out of curiousity I tested my ato water and it was above 2ppm the highest number on my test. But it's the same rodi that tests undetectable silicate. I use a plastic food grade container for my ato, could it leach silicate somehow?

I'm just swapping it to a different container anyway to see if that helps

That seems somewhat unlikely to come from the container, but to keep it in perspective, I dosed each week the same amount of silicate that your water would deliver with a good size water change, so it's not a totally unacceptable amount, even if real. But it is enough to drive dinos (if real).
