Yeah just watch it close test at least weekly if your dosing it. Once phosphate get low enough it will start to rise.

How are you removing phosphates algae scrubber, cheato, carbon dosing, GFO?

think about this so when you start a new tank it takes half a year or more for rocks and sand to stop absorbing phosphates so all appears fine then one day boom phosphates rise dramatically and then you get hair algae on rocks and it keeps coming back as phosphate leaches back out of the rocks as you remove phosphates from water (by pulling it out or other control measures)

need to use one of the mentioned methods above consistently to keep algae growing slow enough for CUC to control but not so low or controlled corals don’t have enough to grow
Ya, I don't really want to dose so I will keep an eye on how much things are dropping.

I have caulerpa in the refugium that is currently being out competed by the gha. I will probably give chaeto a try.

That's a good point on the removal of phosphates. I am hoping I can eventually control it with chaeto in the refugium, but we will see. If not I might try the algae scrubber.

I noticed last night, after lights off that I have tons of small snails all over the glass, but not a single snail on the rocks. Is that odd or is it just me?

A lot of my snails hang out on the glass

chaeto works for a lot of people most dose something like cheatogrow or similar cause it pulls lots of iron or something out of the water

I've heard that before. My last ICP test said iron was 0 so maybe that is why I haven't seen as much growth with the caulerpa.

I was taking a look at some old pictures of the tank and I noticed something.
June 26th - tank and corals were looking good. I did have a bunch of chrysophytes all over the rocks, but things were going well.
June 28 - Elkhorn and forest fire aren't looking great and some cyano is showing up
July 8 - Corals are losing tissue, chrysophytes are completely gone, cyano has exploded on the rocks and glass

Seems like good things happen slowly and bad things happen quickly.

Isn’t that with everything in life

I tested my water again on Sunday night. My main 3 consumption has dropped again.

Temp: 78
Salinity: 1.026
Alk: 9.6
Cal: 485
Mag: 1500
Nitrate: 6.1
Phosphate: 0.07

Still trying to remove as much gha as possible. I'm still dosing live phyto daily, but moved to weekly MB7 dosing. I'm working on getting my Apex to connect to fusion again and I will be looking into ordering some more cuc, pods and chaeto in the next week or so.

Some current tank shots. It's still not looking great, unfortunately.

I ordered a few snails and some pods yesterday. I also got my apex connected back to fusion so I was able to bump up my refugium light time. Hopefully that will help start making a dent in things.

Here's the tank after not scrubbing the rocks or stirring the cyano side of the sand for 2 days.

I'm going to do a 15g water change tomorrow and try and suck out as much of all the nasty stuff as I can. This will be my first water change in about a month. Hopefully there won't be anymore coral losses following it.

The pods and snails I ordered should come on Tuesday. I ordered a pod seed pack rated for 100g tank, so I hope they can help out a bit in cleaning things up.

Since I was finally able to get the apex connected to fusion again, I can see what the pH is doing. pH seems to go between 8.4 - 8.2.

Read most of the thread but not all of it. I have been running sps dominant / mixed reef tanks for some years and by looking at your current tank condition I am mostly concerned about:

1. The lack of coraline
2. The amount of algae

While you could dose h202 or get a bunch of fish / cleanup and limit your light I would most likely just start over as It does not look like your tank matured completely in a way to grow sps.

I have moderate swings in phosphate and alk due to my tank only being 15 months old but 80% of my rock is covered in coraline, no algae and I feed moderately. Water quality may be a concern as well, hopefully you are testing 0 ppm using a RODI.

The Coraline is growing on the side glass and a bit on the overflow/back glass, but nothing on the rocks. It's strange, I think I commented that a few pages ago somewhere. I noticed a similar thing happened in my 25g that has been running for 3 years. Corals died off and the Coraline just completely stopped growing on the rocks. I have noticed small patches appearing on the rocks here and there.

The algae came up after the coral losses started. Before that, corals were growing and some of the frags had encrusted onto the rocks. Then the RTN/STN issues started happening and the cyano and algae came in too. Being away for a few weeklong trips over the summer didn't help things either.

How do I get a tank to mature completely/correctly? I cycled the tank, slowly added a fish and some cuc, then added some test corals. Those corals did well so I continued to add them. What would I have missed? I would prefer not to restart since I have nowhere to house the fish and corals I do have.

Water quality seems to be fine. I check the ro/di once a month and I change filters when it reads over 0.
