I'm planning a tank upgrade in the next few months.
I want to put in a retro 6 bulb kit with 2 ballast HO T5
do i need 2 430's or 2 660's?
The tank will only be 30" long and 17 deep by 17 high. I plan to build these into a canopy with splash shield.
Would the 430's run 3 bulbs---I'm confused by the different ballasts.
What is the advantage of a 660 over a 430 since I'm not running any more than 24" bulbs.
