AI hydra 26 HD on 180g

[LI reefer]

i'm upgrading from a 80g to a 180g (72x24x24) does any one have any experience with the 26 hd? would it be enough light for this tank. im trying to keep the cost down as much as i can but still get good quality.

You would need at least 4, and more would be better for coverage. The 52s you might get away with 3, but either way you will have some shadowing etc. They are great lights, but coverage is key for LEDs... for reference, I am about to order a second 26hd for my 24x24 tank
