Just trying to get a handle on my well water post RODI. I've done several Triton ICP tests and the results for Si are pretty consistant in both my tanks and the freshly mixed salt water. Usually around 125 ug/l. I've had some issues in my older 75G tank with what I'm pretty sure are diatoms and trying to determine if my Si is excessive. I use well water with a booster pump through RO membrane, then BRS Pro-Di (separate Anion, cation, and mixed bed), then another regular mixed DI bed. Triton shows setpoint between 0-200 ug/l. Thanks in advance, if you have triton results I'd be curious to know folks Si readings on city water.
