finally did some tests on the frozen foods
Well, I finally did some tests on the frozen foods, and boy! they were through the roof.
My PO4 test only measures up to 5ppm (the darkest color), and so all of them tested at 5ppm!!!! That's insane. My tap water is 0.25ppm... can this be right?
Anyways, the phosphates are definitely coming from the frozen foods even if the PO4 kit I have is a bit off.
I do NOT use any carbon in my bio-filter.
I raised the nitrates to 15ppm to offset the high phosphates. I'm struggling to see if I can get a good balance at higher settings even though the phosphates are at 5ppm. My algae problem is still there but getting controllable. Not sure what more to do.
Washing the frozen foods every time I feed is such a pain. Not worth the effort IMO. I'm going to see if I can get a good balance at higher levels of phosphates and see if it works.
Thanks for all the input so far! abc
