Lighting - Aqua Glo

[ddavis1979]

I got a 20 gallon long tank the other day and I am working on cleaning it up and getting it ready for fish.

The tank is 30" long and came with a hood and light fixture. The light holds a 24" fluorescent bulb, and it came with a "GLO Aqua-Glo" Light bulb.

Its a 20 Watt T8 bulb that puts out 18,000K color temp.

In my 55 I use T5 bulbs, one 6700K and one colormax (dont know K temp).

What is the general opinion of folks here about the Aqua-glo bulb, and what would you recommend?

A 18,000K bulb is a bulb best suited for a marine set-up. That would give a lot (and I mean a lot) of algae in your FW tank

I would switch to something like you are currently using on your 55 gallon. A bulb in the 6500 to 6700K range

Thanks for the info.

Yeah when i picked the tank up, (it was used), the amount of green hair algae was astounding.

LOL, I know, I tried a 18,000K bulb once as well. The amount of algae that I got was just amazing and it took me weeks to get rid of it all
