Just purchased on Viper Spectra 165w to upgrade lighting.
Tank size 55 gallon 48×13×21 currently running Finnex Sting RAY 2 48 IN BAR
Corals in tank
Two acan
Goni
Duncan
Red monti
Green chalice
Miami hurricane
Gsp

Since I am Upgrading from a poor light to this i did only one I may add a second later on but looking at how high I should mount and starting settings since it is a big light jump.

Any and all input what be great

The great thing about the lighting is you can really dial it down to acclimate the corals and Anemone.
On a 55 gallon I would probably start at 18 inches and adjust for spread.
My fixture is 6 yrs old and still going strong. The Viparspectra doesn't have all the bells and whistles but it grows corals no problem. I have the hanging kit.

Do you only have one light above yours?

 

[Tahoe61]

Yes. The biggest tank I used it on was an IM 40 gallon.

After looking at your tank thread I would suggest two fixtures.

I do plan on doing two fixtures, but since we were coming from such a poor light, I figured I would purchase one acclimate and then add in the second one, especially since I also have to work on a very tight budget

 

[Tahoe61]

Understand.

Great light for the price. Just acclimate slow and hang it a little lower until you get another fixture.
On my IM 14 it's only 8 inchs above the water line and turned way down.

Old light

New light current settings 100% blue 50 white seems like it is less light than the chaep bar it is 15 inches from water.
