Help my frogspawn coral

shark230 · Nov 18, 2020

I have a 58 gallon tank. My frogspawn coral is shriveling up and dying. Is it the flow? My brain coral is bleaching from the bottom. Have had the brain coral 20 plus years. Changed my lighting 7 months ago to AI 32 HD LED light. Last week moved brain coral higher closer to the light. I have 3 hydro pumps : 850 on side of frogspawn blowing to surface. 600 and 425 on opposite side. My calcium is 425. Kh7. Nitrate 0. Should I adjust flow? Lighting? I have a royal gramma in tank with a 5”yellow tang that is not aggressive.
Suggestions?

I would definitely move it to lower flow/lighting if it’s irritated. Have you noticed any critters messing with it? Maybe a fish hates the location of it?

I've never seen a light schedule like this.

This all depends on how high you hang or mount your lights.

Red and green promote algea growth so most schedules have those at 0 or very low.

Whites can cook your coral and unless you have a par meter to gauge what it really is you should side with caution. A lot of schedules have the whites around 25%

Blues and violets can be turned up to your pleasure and many schedules have variations.

The AI app should have a place to download so preset schedules which would be helpful.

Also whats your phos?

Sorry with duplicate photos. Height of light. Adjusted light parameters. Hopefully better?
Phosphorus not tested since add phosban to tank with every water change every 2 weeks

Give them time to adjust but you should see some color come back.

With 0 nitrate and 0 phos you are in a dangerous place...try to get them up.

Do not drastically increase these levels though.
