how Much light to keep a Bta in a 20g long

[Louis Z]

I have a 20gal long and want to have a BTA can i get away with 4 X24watt T5HO. or another option i am considering is using 2x24watt T5HO in combination with a 12000k LED from Build My LED. Any opinions or experience?

I'm not an expert but a 20 long isn't deep. I bet it would be fine.

I kept a BTA for a few years (moved) when I had a 20L. Great tank size btw...I had 4x24 t5ho before upgrading to MH. You should be fine with either option.
