Problems with corals

[blabay]

Tank is a little over a year old. I've had nothing but "ugly stage" since day one.
First diatoms. No problem
Next cyano. Used chemiclean.
Next hair algae. Did nothing but add Microbacter 7. Not sure if that did it but hair algae gone.
Now I have this brown algae taking over my rocks and now sand. Expect its dino but havent verified.

But my real concern is that many of my corals are in decline. Seemed to coincide with my use of chemiclean. Shortly after, my zoas stopped spreading and shrunk up, my acan stays closed all the time, one of my gonis is bailing out polyps now too. Been happening for weeks.
I have a duncan, blasto, and two hammers that are doing great.

Tank is a 54G corner tank. I skim and use carbon in the sump. Temp is 77F and SG is 1.025
Lighting is a Viparspectra 160w - 65% blue for 10 hours and 1% white for 3 hours in the evening.

What is your substrate?
Did you use live rock?
Are you using a dosed Bactria product like Microbacter7?
What is your fish population?
What is your CUC?
Pictures are helpful

Substrate is about an inch of aragonite. 35lbs pukani dry rock. Been dosing MB7 almost daily. 4 fish: royal gramma, solar wrasse, citron goby, and pink firefish. CuC includes about 15 snails, 4 blue leg hermits, tuxedo urchin, and fire shrimp.

Fire shrimp is fairly useless for CUC. I’d get more snails, trochus are awesome. Chemistry looks good based on numbers provided. How’s your flow?

 

[Mr. Mojo Rising]

What is the light and flow in your tank? They look like they are slowly withering away, and your nitrate and phosphate are fine, that leaves light and flow. Even the colour of the algae in the tank tells me something is off with the lights, or maybe lack of flow.

I have 2 nero 3 wavemakers at 40%-25% random flow. Quiet one return pump probably at 200gph but haven't measured flow. Havent measured par and this is a huge concern. I have no idea what it is. I have 2 hammers on the bottom, middle front that are looking great. Also a torch up high that looks good but not fully extending.

Do you have a full tank picture? I’m trying to get a more visual image of what your entire tank looks like with the lights, wave maker etc…

What kind of light do you have and what intensity? to me this points more and more to lighting issue, corals get 90% of their energy from the light, chasing parameters only has so much affect.

I don’t know much about LED’s or your particular lights, but just looking at your zoas they appear to be stretching for light. I have the same bob marley zoas in my tank and have never even seen their stalks. They stay completely open close to the rock. Also, did you do any water changes after using chemiclean?
