Wow interesting thread. Thanks a lot for the info because I might try it myself. I am also running two T8 electronic ballasts from a local light store with a ballast factor of 1.12. But each ballast can light only 3 t8 lamps.
I have a total of 6 T8 lamps in my 75 Gallon planted tank. So do you think it is possible and reasonable to cut it down to 4 bulbs and overdrive an extra 2 bulbs?
I have looked into some of these ballast from Home Depot and inland reef actually uses the Advance Ballast REL-2P60 for power compacts which can be found at 2-3 different home depots at around $20. I gave up on the this alternative because I decided to go for VHO given some board member recommendations.
I called inlandreef and they confirm they use this Advance Ballast.
