rtn with rowaphos?

[Proteus]

Since your using api I'm going to guess and say you don't accurately in now what po4 is

And while they suggest a dkh at 7 its a fine line imo. 6.5 is stn. I too am probiotic but keep alk 8ish

Did you rince the rowa. Its finer partical. I run mine back into filter sock to prevent it from reacing dt
