About a month ago, I was having slightly high phosphate readings (0.1). So I started using GFO
and biopellets. I tested today, and my phosphate was 0. I test with salifert and it definitely wasn't up to 0.03 ppm
. Should I cut back on GFO
or blame a faulty test.
Extra info - 90g tank. 100-150 lbs of live rock, eshopps skimmer (I run it fairly dry because I can't keep up with it), dual reactor running GFO
and biopellets, and a refugium with cheato. I have a bit of algae on the glass, but I believe just as much as most people get. What I've recently scraped, has not come back.
