So reef is really only a few months old and never really tested any other tank like I am this one.
I know the Hanna Phosphate ULR tested has +/- .02 tolerance. But my testing last Sat showed .07 P04, this morning was .03. I don't run GFO or any phosphate reducing media. Don't carbon dose.
I'm not exactly sure how I should be looking at that number or what to take away from that? I really am trying to keep it steady. No cause for concern I would assume?
