Thanks
Tested my water parameters yesterday
Ca : 390. Will top up Ca flakes to 400
Mg : 1380. Will top up Mg powder to 1400
KH : 8.3
NO3 : 5ppm
PO4 : 0.24ppm. Time to change rowaphos
K : 410ppm
Salinity : 35PPT / 1.026SG
Think the last Rowaphos change was on 11th May. That's 4 months ago. Rowaphos is good because also binds aluminum which is a common contaminant in our reef tanks (not sure where the aluminum is coming from though)
I'd typically put in 250g of rowaphos (half bottle) into a phosban reactor.
From the Hanna checker, 77ppb phosphorous is approximately 0.24ppm phosphate.
I lifted the skimmer lid up a few weeks back to get more exposure to fresh air. Still skimming well. This is an hour after heaving feeding of fish meat & reef roids.
Nitrates running ~ 5ppm. Good enough
