I feed the sps corals maybe once a weekbut I hand feed the LPS every couple of days and all of the food is reef rides once a week maybe if not longer and all the Lps and fish food is pre-rinsed
I'd stop feeding the corals entirely. They don't need it, and SPS don't eat what you're feeding. imo most of the nitrate problems people have are due to thinking their corals need food.
Your main issue is probably coral feeding combined with not enough filtration. You're dosing nopox but there isn't enough of a bacteria base to eat it because you only have 60lbs of live rock. I'm not a fan of the ceramic bio blocks since they can leach metals, but matrix or siporax are good choices if you don't want to add more live rock. Like everyone suggested though you're going to have to start with lots of water changes.
Wait why are you reducing your nitrates...... I would make sure to dose bacteria after doing water changes. You are removing the biological filtration and the lack of is resulting in high nitrates. Have patience, there is no quick cure. Oh and I run my nitrate off the chart all the time so don't be alarmed. Just get down to 50-60 and ride it out
So phosphate is undetectable and nitrate is 80. I just shut off the algae scrubber ( I just put it in like 2 days ago so it hasn't even done anything yet) and shut off the nopox dosing. That's the only thing I could think to try to raise the phosphate
Yes regular sugar after 2 weeks my nitrates lower 80 to 15 around check the videos in YouTube I don't use vodka to slow or withe vinagre but for me work sugar good lock
I had the same problem with nitrates. I did big water change one a week. Still didnt work . Added biopellets and it fix my problem. Back to once a month water changes ???
I almost never feed my corals. I thought I saw somewhere to feed them like twice a week. Actually I usually only feed them before water changes since the ones I have live off of light too. I have a small 10gallon system though
