What size tank is it? How many gallons?
For med you need between 2 - 3 watts per gallon. Now I am not that knowledgeable regarding LED vs fluorescent or T5HO Flourescent but I was seriously considering the Sat+ in fact 2 of them but my tank is only 13 gallons in the display area so two of those fixtures would give me med light I would imagine. My tank is only 13" deep and after a couple inches of substrate is is more like 10.5". So I would think that it would work for me. Further if you are going to go that route I would go Sat+ and have 2 of them on there as they can both work in unison off same remote.
Now I think I am going to go with the AquaticLife 4 bulb T5HO unit with 96 watts of 4x24 T5HO bulbs and built in timer and moonlights. I figure I have many options with that light should I ever want to go SW, FOSW, Reef, Planted FW (like I am now) etc. I am going to initially set it up with 2 6700K 1 Pink and perhaps leave 1 10K in there. It has a built in timer with 3 separate grouping for individual on/off times. If I find that 2X24 watt lights are all I need then I can run one group or, run one group for a half ( the 10-12 hour) shift and then the 2nd for the remaining shift (5 or 6 hours) and then let the lunar lights come on for the night. Or just set one group to not come on or only come on for a minute or two and basically just use 1/2 the power or if I find I need all the 96 watts they are there. Beauty of this is good strong lite, built in digital times, only 1 power cord not several, allot of T5HO lights out there. Well built unit. A comparable LED fixture like the Maxspect would cost nearly double. Also these run pretty economically. Calculator said about 3.50 month.
That is just my two cents worth but I think it is a pretty strong arguement for the T5HO's. Par with this set up is not going to be an issue. Plenty there for anything on this tank. Tank is 24x12x13" 16 gallon tank from Innovative Marine.
If I get the Sat+ and later decide I think I want to try my hand at a reef tank I will be out looking for another light. More money.
Also the AquaticLife 4 tube T5HO unit is the same price as 2 Sat+ units. At Least the 24" ones are. Also you then have to2 units sitting on the tank. This unit will more or less cover the entire display surface of my tank from end to end and front to back.
Correct me please if I am wrong.
