Hello,
I have a 100 gallon DT with a 34-gallon sump. Probably 100 gallons total. I run a skimmer, and carbon in a reactor. I have previously run GFO mixed with the carbon but eventually moved to auto-dosing NoPOx. For a while everything was good. 0.1 phosphate, 1 nitrate. Over the last few weeks, I have been having serious issues with Phosphate.
Nitrates now are 7, and phosphates have been 0.5 to 0.61 over the last three weeks. I've been dosing more NoPOx, and as of this morning was dosing 25ml per day.
I feed twice a day. Frozen in the morning, and some frozen at night with a couple of pellets for my Foxface who likes that the best. I haven't dosed any coral foods in probably a week.
It seems like NoPOx isn't doing anything for me. So this morning after testing 0.61 (Hanna ulr), I lowered my dosing to 18ml per day (from 25), and swapped my carbon, and mixed in GFO. 0.75 cups of GFO, and 0.75 cups of carbon, mixed up, and slowly running in my sump. Last week I cleaned out all of the detritus in my sump, and I change filter socks every 3 days. I perform a 10% water change weekly with pre-mixed Tropic Marin salt. Last week, I got a reading of 0.01 phosphates in that bin, and 0.01 phosphates in my RODI bin. TDS reads 0 coming out of the DI resin.
Does anyone have any experience with an issue like this? I haven't noticed coral health issues or fish deaths. Really stuck on what to do next. Someone who used to work at my LFS told me that I could use Phosphat-E to get the phosphates down, and then run GFO. But I'm not sure what kind of impact (if any) this NoPOx is having on my Nitrates.
Thanks in advance everyone.
