For some context, I recently did a hanna phosphate check and it read at .46 the first test and .56 the second. Now of course this is very concerning, but I don't think it's accurate. My tank is 120 gallons, no fish so far and 7 1/2 months old. I'm running GFO and keeping phosphate sensitive coral such as favia and lobophyllia, and while recently I have gotten into the habit of feeding the coral every 2-3 days, I only use ~4 cubes of this really fine coral food
So anyways, it's not much. I clean the filter sock every 2 days and everything else seems to be good. Until I tested the phosphate. A reading like that makes no sense considering the little I'm feeding and the amount of GFO I'm running
Yep, that bag is full of GFO (to avoid the exact problem of high phosphates, added 100 more ml yesterday) I'm also thinking It could be the testing vial, I clean it with RO, microfiber cloth and a paper towel but it still looks like this
Again, the polyp extension on the corals is amazing so I doubt this reading is correct but I do need your opinion, I'm taking a sample in to my LFS to use their hanna/vial but until then I'd like to hear you guys opinion. Thanks!
(Said polyp extension after tonight's feeding,)
