Plants(some algae), yes, but not corals. Just because it's called "coral plus" does not mean it's strong enough to handle corals. What size tank is this? A 4' tank would need a minimum of 4 x 54T5HO over it to keep corals, and I'm talking about softies and LPS
, not SPS
. That's 4 times what you have.
If your budget is the issue, get a hydroponics fixture. They are much cheaper and all you need to supply are the lamps. Plus, they generally have larger reflectors and in turn push more lumens than aquatic fixtures where space saving is important.
