hmmm...
I have seen 280 metal h. on 29 gal, tanks. that is about 10 wpg. is it just me, or is that too much light? I'm asking because i want to upgrade my lights, but don't want to hurt some thing in my tank. also how huch heat do m.h. put out (175 watts)? will i have to get a chiller or is 4" above the water and 2 fans enough to keep my tank from frying? please reply

I think the wattage is fine, depending on what you want to keep in it. I don't know if there is such a thing as too much light. You may want to short cycle your MH when you first get them to let things acclimate. Fans will certainly help keep stuff cooler at the price of evaporating more water. Fans helped tremendously with my tank. There are a lot of factors with heat in a tank. Glass or acrylic, submersible pumps, AC in the house etc. A chiller helps make it more of a set and forget setup. Without it you will need to keep a constant eye on your temp in the summer or maybe even winter for you in Dallas. Chillers for that small of tank are a lot cheaper compared to larger tanks. |

I have 2 170gph pumps, and a 290 gph pump. It is a glass tank. And yes..the evaporation is hell. About 3 gallons a week!!!!  |

3 gallons a week is pretty low compared to most tanks. My 120 probably loses 3 gallons every 2 days or less. But, evaporation cools the tank relatively cheaply.

Seems normal to me. Are you running fans on it yet?

4" off the water is way to close. Most people run them around 8"

Do you have fans? They make a big difference.
