Fluval sea 32gal tank with the Fluval smart led that came with the tank. I have the main return and 1 hydro 425gph.What kind of lighting?
What size tank? What are you using for water movement?
You also mention it has been like this for a couple months. How long have you had it and I am guessing it looked more normal prior to this?

I’ll try to move it back up on the rock work slowly and see what happens I really need to get a par meter or rent one. I’m still learning about par and figuring it out. Thanks so I’m guessing it’s trying to get more light. ThanksSO I was looking at the Fluval sea marine 3.0 36" fixture following specs:
Features:
According to this PAR at 12" is just under 100.
- This 36 inch light has legs that can expand to 48 inches
- This light is controlled with a the Bluetooth in your Android or iOS (Apple) device (phone or tablet)
- 46 watts
- 25,000K color temp
- At 3": PAR=381, LUX=16,720. At 12": PAR=94, LUX=4160. 1950 lumens.
Your Tank is 15" deep? Light is 42W not 46 like the 36" version, so your probably on the low side for light as I think the 32" tank setup you have is slightly lower power than the 36" model. Rough guess is you might be hitting 75 PAR on the sand bed?
Maybe not enough light? I would be shooting for 150 at least.
