Alk not dropping, SPS not growing

[Bbio]

Slow growth can explain the stability in your parameters, especially if your feed input is low.

Since these parameters seem fine and your corals are otherwise healthy, I'd personally look into the lighting first. Is it possible to increase some of the other colors (i.e. not blue)? SPS often appreciates a good spectrum of light from what I've seen and heard. I know people who swear by T5's and halides for that reason when it comes to acros.

That's just what I'd try first, even if it sounds a little "outside the box".

I started with my lights on 60%bv 15%WGR until I got a PAR meter. I found out I was getting ~100 on the sand bed and ~150 at the top of the rock. I slowly raised it over a month or two to 100%BV 25%WGR which is where it sits now. I’m getting ~150 on the sand bed and ~250 at the top of the rock work.

I struggle to keep N/P up. I excessively overfeed dry and frozen foods, only change filter socks when they clog and overflow into the skimmer section, have my skimmer turned way down to where I only empty the cup about once or twice a month, have a really small photoperiod for my fuge and dose N/P

Sounds like my SPS tank. I have ammonium on a doser to keep nitrate 5-10 I have dosed phosphate as well but that's finally staying above 0 now.

In your opinion should I keep dosing? In the last 10 months N/P have bottomed out twice but I have not dosed in about a month and they seem to be stable at N: 3-5 and P: 0.02-0.05

If your LPS are looking healthy I would just keep an eye on it. I'm pretty much good with anything but zero and don't fret it much.
I am seeing a good response dosing ammonium in my sps tank so I'm going to continue as long as nitrate stays 5-10.
I'm surprised my LPS aren't minding the higher flow and lighting. The blasto has babies hanging off.
Par is a bit over 200 on the LPS rack increasing to well over 500 on the acro high in the back.
PS this was a tank move and still a work in progress.
