SPS

Wouldn’t chlorine show up on ATI test?
I also run 3 cups of carbon in reactor changed monthly.
Here are those tests from 4 months back .
I since corrected my salt, mag, po4

I would run a cup or less of carbon passively, do 10% weekly water changes, feed fish well and make sure nitrates and phosphates are measurable. Nothing else. I think it will turn.

Calcium at 385, should be at 405.564…..well that is a joke, your parameters are all in range, personally I like nutrient lower but regardless.

If you’re open to ideas, here is mine….turn on your skimmer 100% of the time and filter your water and do WC. Add fish and feed your corals directly daily with pumps off so they have time to absorb the food; I barely feed fish they get leftover coral food. Fed the corals and don’t worry about gearing in your inorganic nutrients which only feeds zooxanthellae and not the corals directly.

Calcium is pretty low. Flow is importance and light as well but one Of uber biggest factors is who you get them from. Get aquaculture instead of mariculture.

Thanks for feed back. I will clarify a few things.
Friends think my Alk consumption of 120ml /day is weird due to not many corals in my tank . Is the Coraline consuming that much?

Could be, that is a lot though.

-Skimmer off 14 hours because I had trouble keeping Nitrates above zero. Had to dos NeoNitro and double my feedings to get a no3 value of 4.8.

And you have no coral to feed. So why the skimmer off? To raise no3 to feed.... IDK.
Skimmers have more Benefits when used 24/7.

-Cut my UV back cause read an article that said I might be killing off beneficial bacteria needed for corals .
-Just retested my par 225/245 and I’m not at peak yet .

I would just shut it off and see how it goes at this point. Your killing the bacteria rimming it even part time. They can't know when and when not your running it. They are still passing through.

How long are you running the lights per day?

Mag was accidentally high over 1600 for a while and thought that was a reason.
It wasn’t. It’s now 1400 which isn’t low according to what I read.
Back to Alk, to me it seems odd I need 120ml per day to maintain what a normal salt mix should test. I haven’t done a water change in over 2 months. Reason being because my water was testing to clean.

Have you checked to see if your sandbed is hard?

I agree with everybody above that you don't have enough light to grow acros/SPS well.

Couple of questions that haven't been asked:

1) What is the fish stocking list? Fish poop is an excellent source of coral food and is easily converted to something they can use. I like to overstock/feed and heavily export anything extra. From the pictures I would add A LOT more livestock to the tank.
2) Where are you purchasing colonies from? Lots of people asked about Maricultured vs Aquacultured. Mari* corals are notoriously difficult and typically do not do well outside of the ocean. Purchasing colonies is also very difficult in that the overall 'organism' is used to a set of water parameters and you can get pretty quick die off of sections that are either in too little light or flow, or the opposite of too much. Well known varieties/strains of aquacultured 'frags' are the way to go for long term SPS success. They can adapt to your environment and won't kick the can if something is just slightly off that they don't like.

No it would not. If you haven’t changed your Carbon Blocks in your RO please do so asap and then put them on a schedule. I do my first one every 2 months and second every 6 months.
