I have run a search on this and came up with many posts. My question is which ballast do you feel is the best, and why also the same on the bulbs. I am looking at adding 3 or 4-400W MH lights to my 200 gallon tank. It is 84x24x24. I also have standard 40W bulbs that were given to me that I will use for fill light :
2 Motorola Rapid Start Ballasts Model M3-RN-T12-1LL-12
1-Coralife 10,000K
1-Coralife 50/50 50% 6000K Daylight, 50% Actinic 03 Blue
1-Coralife 20,000K
1-Coralife 100% Actinic 03 Blue
Also do you have any suggestions for building a hood with this configuration since the Coralife bulbs are 48".
