Hi all,

I’m two weeks into my fallow period for ich and have a tank full of lps. I’ve started dosing aquavitro fuel and target feeding twice a week which made phosphates go up to 0.1ppm per Hanna checker. I threw in some phosguard and the next day it was down to 0.02 and stayed there so I set the reactor to only run 8hrs a day. On Monday, phosphates shot up to 0.36 so I started running the reactor all day to bring it down but it bottomed out phosphates yesterday. I dosed phos back up to 0.02 and turned off the reactor but tested my dKh and it went down to 8.2 from 9. I dosed about 10mL of aqua vitro eight.four which usually brings it up to 9.0, but only brought it up to 8.3. Today, phos bottomed out again, and dKh is down to 8.1. The only recent changes I’ve made is the addition of a co2 scrubber. Any suggestions?

salt: 32.6 (apex)
ph: 8.16 (apex)
No3: 10 (Hanna)
Po4: 0 (Hanna)
Ca: 450 (salifert)
Mg: 1455 (salifert)
