Maybe this will be helpful to some people who are getting started themselves.

My tank will be about three months old here in a week (I’m not counting a crash due to Petco carbon since I had to rebuild with all new rocks and sand).

It’s a 20G IM Nuvo AIO. I have a UV (rarely turned on, mostly for bacterial blooms), carbon, and a Bubble Magus skimmer I run sometimes. I have a refugium with chaeto macro algae and a little rubble in it.

I noticed a little while ago that the refugium had two different types of cyano bacteria in it, red and green. I have had no cyano ever appear in the display. I attribute this to low flow in the refugium.

My ugly stage consisted mostly of diatoms which went away within a couple weeks. A few types of algae have shown up but nothing has become problematic yet. I attribute this to the fact that I dose some PNS ProBio into the tank almost every day. I also have tons of happy copepods and a good piece of live rock which I think helped.

I dose a little under 2 ml of All For Reef every day. I dose ChaetoGro twice a week. I broadcast feed YellowSno twice a week. I dose ammonium twice a day to keep nitrate and phosphate above zero (overfeeding wasn’t working).

My corals are thriving. Softies, LPS, and SPS. My newish torch is splitting. I unknowingly got some candy cane coral that looked dead and was a frag base for some Anthelia, but it’s growing, glowing, and puffy.

I do water changes every three to four weeks.

I suggest people look into copepods, ProBio, YellowSno, and All For Reef. I believe using those has really helped me minimize issues so far and make my corals seem to thrive.

I have the same tank and get some interesting growth in the rear chambers. I'm thinking of making some type of cover to keep the light out. I have a mini Q skimmers but pulled it. I run no mechanical filtration except some floss in holders when I'm scraping glass or blowing rocks off.
I too use AFR and dose ammonium bicarb to keep nitrates detectable. I don't add the other stuff but I started with all old live rock and was able to add livestock the next day so it's not really like a new tank, or at least not like a new tank started with dry rock. Live rock is a game changer IMO
