I have a 90 gal dt with a 8 bulb t5ho fixture 5” above the water .
About 6 months ago one of the ballast went causing only 4 bulbs to work .
it’s worked but I think it’s been only bare min
I’m adding a new ballast this evening .
My question is , adding the 4 bulbs to get the fixture back up to full lighting , will that effect the corals ?
