Your tank to me just looks like you have high nutrients. The algae on your glass and rock just looks like the dusty algae I get when my nutrients are high. When my tank glass and rock gets dirty after just a day or two, it’s typically a nitrate/phosphate problem. High PO4 puts the brakes on growth in my tank and colors suffer too.
Chemi clean won’t fix that.
Given how many fish you have in your tank, you probably don’t need to use Acropower as it’s just adding to the problem. It looks like you have a purple, naso, gem, and yellow tang? Despite the tank being too short for any one of those, it’s just a ton of fish for that volume of water. I know you said your nutrients are in check, but your problem just look like a nutrient problem to me.
Yes, SPS is slow but after a year, you should have some pieces that have many branches that are multiple inches. On the other hand, you’ll have a few that have barely grown.
