Your tank is looking very good.
I got my nitrates down by half by cutting feeding in half e.g. meaty one day dry the next I have 24 fish and some are big so have to make sure they get enough, they get the same as if I was feeding once a day but have changed it into four feeds. nori in morning for tang, angles, trigger and anyone else that wants it, I add fresh crushed garlic to it and fold it up. Lunch is pallet or frozen dinner is spirulina flake supper is cyclop-eeze.
I have found the fish let you know if they aren't getting enough. It's a pain having to feed like this but I am home all day so can do it.
The trigger stopped nipping my butterfly fish as soon as I went to four feeds.
I also add vodka 5mls twice day for 1000net ltrs
Do water changes monthly now which is over due because of rain and the nitrates are 15 which I am happy with.
More important to me is Phosphates I run a Deltec reactor for this.
