My recent BAD outbreak was caused by nitrates in the 70-80 range. BTW my cheapie test kit had been reading 20. I got a Lamotte kit and was quite surprised. I did some massive WC's to get it back down in the 20 range. In only a few days it's really started to clear up. I previously had to scrape the glass daily. Now it still needs it, but only about once a week. I'd recommend calibrating / checking your test kits to make sure your levels are really what you think they are. |
