Do you think that 250 watts on my 13.5 gallon cannot be successful? Assuming that the fixture will be hung near 12 inches from the water surface, and with fans blowing over the surface of the tank.
Sorry I didn't answer directly the first time.... :rolleyes::D
I think you'll need it to be higher than that for the heat factor.
As a result you will probably be lighting the room
even more than you'll be lighting the tank.
Note that neither the UV nor the blue light that exit the fixture are good for your eyeballs.
"A little light spill" can be tolerated by most folks, but with the light at that height you'll be living in a
bright, 20,000K room – not just spilling "a little out from the tank".
We'll see how it works out though...maybe you'll actually be able to do a lower height due to other more-favorable ambient conditions like low temperature and humidity levels in the room air to promote evaporation with the fans.
I want something simple that just works. I find that if I have something to tinker with, I will never be happy with how it is. The MH setup is appealing to me in that you set it up, and can't mess it up too much [aside from heat or acclimation issues].
I think this fixture kinda fails on that count, IMO...
Everything about it needs to be replaced....bulbs first, but probably ballasts too.
You don't have a go-to, favorite halide bulb yet, or a favorite combo of T5 bulbs.
Between those two items, I think that represents a lot of potential tweaking and indecision, etc, as well.
And yes you will have to figure out the heat issues on top of that. ;)
Unless you've already ditched the LED's I wouldn't consider them a lost-cause.
Depending on the vendor's return policy on the halide system, try it out.
Just be prepared for the issues mentioned and if they are insurmountable, then you already have a good fallback in your other lights.
Worst case scenario is that you can sell the unwanted system (either one) used....not so bad as long as you end up with lights that you and your corals like. You even end up with some experience with both sets of lights! :)
