Hahaha, I see it now but woulda never guessed it

Are your water params fixed now last month your calc was like 310 did you ever test your phosphate? Your mag was also super low.

My all is a stable 7. Cal still stuck around 310, I never been able to get it higher than that since I started my tank. Dunno why. Mag around 1200. I'm going to JL today to buy a phosphate test kit. I'm running one of those phosphate remover bags passive in sump in the same chamber as my carbon bag. Maybe the carbon is making it neutral? Should I run the phosphate bag in my filter sock instead? I was gonna order another led fixture today as well because I only have 1 16" fixture for my 4' tank this whole time. Also the tricoloured nana colony I got from you is starting to brown out the same time most of my other sps are as well. So I'm not sure of my lights are losing quality over time or not.

I would not buy any equipment fix your calcium problem.

Ok this is rly weird. So I just bought a sail feet phosphate test and my results was 0 and nitrate also at 0. So how come I'm getting so much long green hair algae blooming everywhere?

You'll get growth as the algae is consuming stuff and keeping your kits from detecting it

I'm currently fighting a nasty GHA outbreak after 2 years of no problems
It's just a part of reefing

I've cut my fish food back a bit and added more hermits and snails
I plan on plucking crap out this weekend along with some LR turkeybasting, and beyond that I'm not going to worry about it
I love my tank but have better things to do with my time

Got a pic of this algae?

From the pics corals look healthy and new growth is always gong to be brighter , it's keeping that bright is what's tough.

Agreed Raising your calcium would be beneficial

And fwiw some algae require very little nutrients and do quite well even when our low grade kits can't read them.

Here's a pic I just took of an area I haven't been able to reach and manually pluck yet. I've been manually trying to take out as much algae as I can. I currently have my API phosphate remover media bag In My filter sock and I also purchased rowaphos but if my reading is 0ppm of phosphate should I still add rowaphos or no? My tank has never looked so hideous with long hair algae and most sps browning out. Sometimes I don't even want to look at it.

I had the same issue when I started. SK8R wrote up a great post on RC explaining the relationship between alk, Ca, and Mg. From reading that post I only concentrated on getting my Mg stable first. Once it was around 1400, all my other parameters were easy to get in line.

None of that will help with your GHA, but thought I'd mention it if you wanted to read the thread and maybe help fix that little problem :)
