I am running coco DTW using maxibloom, protekt, and a little bit of PK boost along with a tiny bit of cal mag. I don’t kill my res, but I have considered it. How often should I be draining an refilling the res?

I run a similar system, top feed drain to waste, I wash out my 55G barrel reservoir after it gets used up, approx every 7-10 days, if I have to refill without washing i clean the screen in my pump line an extra time or 2. I use a pressure washer to blast everything clean between fills, mix nutes with a pump running. Check PH every 2 days & adjust if needed.

Def should be sterilizing at least once or twice a month to be safe
