Lighting question??

[markhom]

I have a 20 gal. nano and need a new bulb for my MH what kind would you recomend, and what wattage should I get.

Stick with whatever wattage it came with, YOU CANNOT drive differing bulbs on MH. 150 is 150, 175 is 175. You run the risk of damaging the bulb or having a blowout (= really sucks big time!).

As for bulb choice, is the MH the only light you have? If so, consider the 14K Phoenix.

If not, put in a 10,000K Ushio and run good actinics to supplement.
