who uses red sea test kits (po4)

[Proteus]

so i had a po4 issue and since picked up a red sea test kit as there wasnt any hannas at lfs. i first tested and sure enough i had excess po4. i changed added rowa and tested few days later to get .08 thought that was strange so changed rowa thinking it may be exhausted (i never added much)
since then test kit has been constant at .08. weather it from tank or reactor outlet.
i also replaced the membrane and corresponding filters as my ro was also .08.

i did some reading on r2r and rc to find that this is a common find with po4 kit with red sea acknowledging this is happening but still insisting that its not the regent. they even sent out replacment regent to find same problem

so $180 in the drain because of a $40 kit


i am going to get a hanna asap
