i got two MH
reflectors with mogul bases coming i need to buy a ballast.
i was looking online and i saw 250 watt dual PFO magnetic ballast for $143 then i saw 250 watt dual HQI PFO magnetic ballast for $239. whats the difference??
also would i be able to sustain a full reef with 2x 250 watt 6500k MH
with 2x55 watt CF
? i have 120 gal
one more stupid question if it was you would you go with 400watt or 250 watt. i know i can get away with only 250watt , but i was thinking the more the better
