or do they require a ballast??
or do they require a ballast??
I'm going DIY on mine only problem is I do not know how many MH bulbs and
what wattage they need to be I will also have CF lights that will come on first
before the MH.
Using a aquarium calc its about 360 gal tank 8 foot long and only 2 foot deep
and im going to have a reef live rock fish the whole 9yards.
Any suggestions as far as MH total wattage how many bulbs and what wattage per?
That's a magnetic core & coil ballast. That will work fine if your not afraid to wire it yourself. You may want to look for 250w tho. 400w for a 24" deep tank is not really necessary.
