Hello Everyone,
Backstory: A friend of mine had this tank for about 2 years and couldn't take care of it anymore so she gave it to me. It came with a clownfish, coral banded shrimp, a couple snails, conch, and the damsel. When I got the tank it was in rough shape so the day I got it I did a 50% water change and changed out the sandbed. I let the tank do its thing for 2 months and then added some corals and a diamond goby. A month later I added a green clown goby who is about the size of a pinky nail right now. And then this month I've added a 6 line wrasse. The day I got the tank it was absolutely covered in cyano and algae and I've been struggling with it since - it is like 99% better but I still see my nitrate is high.

Routine: Weekly water changes of 5g; no dosing or anything else going into the tank. I go in there every other day and use a turkey baster to remove any algae growth I see on the rocks or corals.
Feeding: Frozen Mysis cubes, I cut them into 4 and feed 1/4 cube in the AM and 1/4 cube in the PM - the fish seem really aggressive for the food so I'm not sure if I'm feeding too little, before I reduced feeding about a month ago I was using the pellette food but was overdoing it.
Nitrates were stable at like 10ppm until yesterdays test. I did notice some dead spots on the sand where fish poop was accumulating so I put in a Jebo powerhead at the bottom of the tank to try and add more flow down there. I kind of suspect that might be where my nutrient buildup is happening? Maybe I should add like a baby brittle starfish or something?
Most of my corals seem to be doing well, with the exception of one of the monties - it kept getting harassed by the snails so I moved it onto a recovery rack and it just continued to bleach, I don't think it will pull through. The psammocora seems to be browning out a bit, I suspect due to the high nitrates. My zoa's just won't open - they partially open and I was told I might need to turn my light up so I put it into acclimation mode and am slowly raising it over the course of 45 days to match the lighting schedule of the guy I got them from. The pocillopora is taking off, looking really good and I'm seeing new growth and it just is a happy camper, same with the forest fire monti.
I'm not sure how to address the nitrates; I'm not sure if I'm overfeeding or if it's the dead spot between the rockwork where poop is accumulating. I don't have the space in my filtration champers to setup a refugium or anything, and I'm scared if I start carbon dosing I'll mess something else up.
For the most part, everything seems to be happy - but like I said, a couple corals look unhappy one is probably going to die and I'm doing my weekly water test seeing everything remain stable except for nitrates.
Any help is appreciated!
