As I looked at my sand bed tonight I had a thought. Perhaps the water I got from Kroger was a main cause of my phosphates more than doubling a few days ago. The cyano on the sand bed is dying off and the last pockets of nuisance algae are dying off as well. It’s not dying overnight but as it dies it’ll release its nitrates and phosphates to the water column. It’s also dying out in the sump which is impressive (at least to me lol) considering the two grow lights on it. They’re much stronger than my T5s.
I got some distilled water today to use for dosing phosphate-e and topping off. I’m going to try dosing minute amounts of it on a constant basis. Of course I have to test daily and dial in the right amount, revising it as I get more coral and if I make other changes that could effect phosphate production and consumption.
It’s looking like near blizzard to blizzard conditions are expected here Thursday into early Friday morning although that still could change. I’ll be able to get more distilled water this week but if the system is as bad as it looks like I’ll have to get about 5 gallons because we’ll be snowed in. I have everything else I need though. We have an assisted living facility close by that’s on backup power and our apartment complex is likely on that system too since we have yet to lose power for more than 5 or 10 minutes even in bad ice storms.
