Insane po4 consumption

[Randy Holmes-Farley]

It is a frag/grow out tank so mostly frag racks, tiles, and some detritus that settles on the bottom.

OK. Coral skeletons will take up some, but mostly it is likely consumption.

Yep it may be consumption, just seems unreasonable for this amount of time. As I turn up the doser alk consumption goes up.

Also tested against added po4 into tank water and came out reasonably close to what was expected. Serial dilutions may have been off by a bit but reading was 0.5ppm and expected reading was 0.4ppm.

Thank you for the help Randy!

Most people do not realize that foods provide a very large amount of N and P. If a frag tank is getting less food than a reef, then demand for N and P may be quite high. :)
