james1542 I love my 16.5" sunpod. It's a 70 watt hqi, mounted on legs right over the tank, and it doesn't heat my tank up over 73 F. My tank is only 14 gallons. I've melted a few plants when I first switched too it, but now everything thrives.

and the bulbs are under 30 bucks, probably get a new one every 2 years. For the wattage, it's hard to beat those lumens

depends on how high your fxture is , what kind of fixture(reflector), are you adding lots of co2, what type of bulb, type of plants, effort you want to put into prunning

i have 3 150w halide lights, all are about 36 inch above supstrate, wide tanks, wide reflection, high co2, 8000k bulbs, ei dosing
plant growth is fast, algae not much of an issue

DogFish For me it's the energy $$$, bulb replacement $$$ and the heat.

I'm able to get the growth I need with 2- 18w PAR38 LEDs at a lower cost with a 50,000 hr life expectancy.

oldpunk78 I'm in a hot climate with a 16g tank and a mh fixture. The light is way above the tank though. I love the look. Nothing bends light waves like an hqi fixture.

willknowitall yup not good for small tanks
you need at least 18 inch from front to back. 24 inch or wider is ideal or your just thoughing to much light on the glass

also if you live in a hot climate they give off too much heat

CatB i think most people don't have a tank large enough. if you put a MH over say, a 20 gallon tank, the plants will only suffer unless you hang it waaaayyyy up. i've seen plenty of others with 80+ gallon tanks using them, though.

Why not more metal halide?

Just curious as to why more people don't use these. I use a 175watt over my 80 gallon and it makes the tank look amazing, natural looking shimmer along the substrate, plants are growing like weeds, and it's super easy to move out of the way when I want to aquascape.

Is there something better I'm missing out on?
