2 fluval marine 3.0 on a flex 32.5

Floedog · Feb 21, 2022

I have 2 Fluval marine 3.0 lights on a fluval flex 32.5. I wanted to know the best settings to maximize the healthy of my corals. Tyia!!

No idea on the Fluval marine 3 light settings, but I can bump.
p.s. I guess you have the fluval flex tank?

I only have one, and I am trying to figure out if I need the 2nd or not.

I had 2 on my tank but I really could never find a sweet spot. It seems if you go to much white lights you get a lot more algae. I kept mind more bluer. Eventually I just went with 2 prime 16hd’s.

Ai primes aren't an option (I'd do it in a second)... My wife's cat is the aquariums second biggest fan after myself... open top, he'd need a snorkle... haha

I just made a wood canopy to house my double light setup. The standard Fluval top isn't very well thought out. I have temp issues with mine and the feeding door sucks.
If you'd like to see my canopy, (it isn't fancy but it should work just fine), I'll post pics when I get home.

They also make DIY kits for mesh tops. Some people don't like mesh, but it prevents fish from getting out....or cats in...and does not block light, or hold heat in...more evaporation though.

I made an acrylic+mesh top for mine. Not fancy as the stock lid but now I can use proper lights and I reach a decent pH.
The fluval flex lights are good if you want to keep softcorals only.

Did you end up upgrading the light or still using the 2 marine 3.0? Contemplating on buying another stock marine 3.0 to add or use an alternative light. Eventually I would like to grow some nice corals.

I did put 2, but I ended up upgrading to a larger tank.
