I spent a couple of months soaking pukani in tap water from the garden hose, draining it every week or two. Then, due to a cold snap and the knowledge that I'd neglect it, I drained the barrel and let it sit dry for a couple of months. Last week, I filled it back up with RODI water and tossed a small powerhead in there. I want to see if I can get all the yucky and leachy stuff out before I put it to use. So how often should I test for phosphates? I'm not curing it in saltwater, just RODI for now. Once a week? Every other week? Water changes only if phosphates are high? TIA!
