Metal Halide and no Chiller?

You could always run T5s. Much less heat, and not a expensive as Solaris. When I ran them I had to dial back the fan that blew across the top of my tank or my heater would come on in the middle of the day.

Sick of the MH heat thing really... but they do supply most of the heat for my house in winter. I might yet go back to T5s, Hmmm... but I'd loose the ripple effect *sigh*

What was the T5 wattage vs the MH wattage that you are running now?

Have run with Solaris PFO LED lights for almost a year... no chiller required, temperature fluctuation of 1 degree at most.

Which solaris unit are you running? and how do you find the colour and brightness compares to your MH setup?

That would insinuate that I put batteries in my thermometer and check the temp when I did look it would go from about 72 to 88-89 in the heat of summer with no problems it is in the basement with dual 250 and T5 actinics, but this is Alberta can temp can go fron -10 to + 20 in a day
