I am looking to purchase the AH supply 55 watt bright kit. Which bulb would you recommend for a non-specialized freshwater tank pease? (20H tank, 55W bulb)

Would I then require a CO2 setup or is this not necessary, I would like to avoid t if possible. I have not ordered yet so I could get the 36W if that is more suitable.

If you were wanting not to inject C02, I would tend toward the lower wattages. I am running a 65W PC Coralife, but am using pressurized CO2. you might be able to get away with using Excel with the 55W, but your life would certainly be a lot easier with 36W I think.

Oh yeah, I would go with the 6700K...it would be whiter.

6700K. Go with a 36w setup if you don't want to do CO2.

Like 2wheelsx2 said, you might be able to get away with just Excel on 55w and 20 gallons.

6700K, 36W purchased.

Pity I did it on a week where there seems to be two postal bank holidays (MLK Jr and Ford rememberance)
