HQI and water temperature


Do HQI bulbs increase water temp by a considerable amount? I am looking at using either two 70 watts hqi, or one 150 watt hqi over my tank. If so would fans be enough to keep the temp down?

I live in sunny ca, and have no AC. In the summer it gets warm in the house. On my old reef tank I had two 175 mogul halides on my tank. I used a chiller to keep things cool, but the room would get really hot. I dont want to use a chiller again, because of the heat emission.

Depends on tank size, proximity of the fixtures to the water's surface, etc.

How big is your tank?

Fans would be able to handle most of the temperature rise at the expense of water evaporation.

2x70W MH should work out pretty well.

Shoot a PM to bharada about your setup. I believe he runs 2x70W over a 40g breeder. Lives up in the Bay Area too. He'd know best.

Do most of you guys who run HQI have open top tanks? Is water evaporation a problem if you use glass tops?

Many/most do, yes.

No, evaporation isn't a problem with glass tops, but heat and light penetration (condensation of water on the glass tops) start to become problems.
