All In One Bio Pellets advice and PO4 dosing

[ksicard]

Hey all,
I have a 150 SPS tank with a frag tank plumbed inline to the same sump. I have quite a few fish and as a result my nitrates climbed up over time to about 20-25ppm. I had my bio pellet reactor in storage so I pulled it out and set it up 2 weeks ago. The bio pellets just kicked in and I'm having an issue were PO4 is 0 (hannah checker) and the nitrates are about 16ppm. I think my mistake was that I didn't take my GFO reactor offline soon enough causing the imbalance. I'm kinda worried with such low phosphate levels that my sps might start to suffer. 1 of my frags in the frag tank started to STN. I trimmed off the STN part but I'm kinda worried that the problem might spread if I can't get my po4 back up to 0.02-0.05. What i've done to rectify the issue is taken the GFO reactor offline and I have been feeding pretty heavy to try and spur some PO4.

I've read about people dosing PO4 and NO3 and I wanted to ask what product can I buy to be able to dose PO4? I would like to correct the imbalance by dosing PO4 to get my levels back up to detectable.

I would try dosing frozen fish food. Good luck

I quit carbon dosing for the similar reasons. One thing that seems to help with SPS is keeping your alk down below 8.5. I'm not sure if you're chasing numbers or had too much algae as a result of the elevated nitrate. TBH I wouldn't get too worked up if it was just the number. IME you risk losing more frags if you don't dial the reactor way way back. I had luck with doing a 10-20% water change as well. Good luck
