So I'm trying to setup my 115 gallon tank and I'd like to have MH lighting at a somewhat reasonable price. I was at lowes and this isn't the exact picture, but it is similar to the image below, with out the sensor.
I was wondering if anyone had any experience setting up a MH like this. My thoughts were that you could pick up one of these 400w fixtures for $20 and replace the bulb with a standard aquarium MH bulb (ex. Hamilton 20k HQI).
Is this possible? Anybody doing this currently?
