Diving in and Need Help on # of LED fixtures
Been reading the forum for some time, but just joined today to hopefully get some help. I am having a custom acrylic tank built, and ready to start my first planted tank. Here is the set up I will have waiting for the aquarium

112 gallon tank
60" x 24" x 18"

Fluval FX5 filter
Semi Automatic Dr. Foster & Smith CO2
API First Layer Pure in the substrate
Marineland 48"-60" Plant specific LED fixture

Now, my major question is whether the one Marineland fixture will be enough to grow plants, or if I will have to bite the bullet and purchase another one.

Thanks so much!!

The Marineland fixture will not be appropriate, as the light itself will only cover about 48" of your tank - right in the center. It won't provide much for the six inches of tank space on either side.

Have you considered other LED lighting options like those from Finnex? They're a forum sponsor and are worth checking out.

What kind of plants will you house? Will you be dosing ferts? Using CO2?

I actually already have the Marineland light. I was thinking about getting two (if completely necessary) and offsetting them so they covered each side of the tank. I wanted to see how one would produce before spending the additional money.

Yes, I will be using a CO2 drip and ferts.

Let me restate that. I have the Marineland light. I bought it on eBay, I suppose I could re-sell it if need be if Finnex had a led fixture that would work, but looking through their site, it seems they do not have anything that would go 60" across.

The finnex fixtures have pretty good coverage/spillover. I have two 48" ones for my 60" tank coming this weekend. I'll let you know how it does.
