Banana Grail Turning Green

[Mike from Penna]

I was hoping someone could please help me understand why my Banana grail is turning green and losing its bright yellow color. It looks healthy otherwise.

I'm guessing its the lighting. I hear conflicting information from people telling me bananas need LOW PAR and others saying HIGHER PAR. I have a SUPER bright banana coming this week and want to ensure proper placement in the tank so its stays bright and yellow.

My parameters have remained fairly stable and I target:
Alkalinity: 8.25
Calcium: 400
Magnesium: 1400
PH: lower than I would like but the range is from 7.75 to 7.95.

My last ICP test the end of July showed 100%. Although I plan to send another sample out this week as I've added more fish & corals since that test.

I add the following daily:
Tropic Marin trace elements K+ & A-
Phyto
6 drops (150 gallon tank) Korallen Zucht Coral Booster

The tank is about 4 years old and I have about 50 torch corals. The other torch coral colors seem about right.

Thanks, Mike

Torches typically change from lighting like you mentioned… I know in my tank if I wanna pull yellows or bright golds I put them in higher par typically around 500.

Different coral but same mechanism I believe…I got a bright yellow Acro last year that broke in half while gluing. I placed one piece in the very top of my reef and the other slightly lower, less light, not thinking much about it just trying to place to look good. Several months later the lower is very green compared to the higher…so maybe high par less green?
