Lighting help

Hello everyone.
I have a 210 Oceanic with center divide glass.
I have had an assortment of lights in the year+ I have had the tank. Lights from prior owner, cheap eBay 72" - T5s that didn't last 6 months, then back and forth with Marineland and Fluval Reef 2.0s.

So I broke down and picked up two Kessil A360WE.
So I have a 3 foot Fluval 2.0 and the two Kessils.

How should I go about spacing the lights. I am planning a part???
The tank is 6 foot long, 2 feet wide and 30(29") deep!

Most of the corals I have now are low light corals and mainly on the right side of the tank.
The Kessils are supposed to cover 24"x24"x24" per light.
So would it be best to use the two Kessils to cover half and the Fluval2.0 to cover the other side until I can save up to buy 1 or 2 more Kessils.

Also do I lower my mushrooms Hammer and Frogspawn until the get adjusted to the more intense lights?

Instead of moving the coral can you alter your light intensity. Your tank is fairly deep but I wouldn't doubt you'd still bleach your coral sitting on the bottom at full intensity.

I think you are heading the right way with your thoughts,and I agree to put both Kessils on the same half of your aquarium and see how that affects your coral.It is a good idea to lower your coral initially as well,or,raise the units higher initially from the coral,if you can,until a suitable level is hit upon.That way you just raise or lower your lights as required instead of the coral.

Thanks. I have an OLDER(2000) Metal Halide with 400 watt bulbs.
I can FEEL the money leaving my wallet when it is running.
I will probably decommision that unit once I am all set.
And after I get the additional Kessil, maybe use the Fluval 2.0 as a backup or added light
