Temporary 2 bulbs for 75G?

I am going to replace my lighting bc two of my ballasts are broken so only two bulbs are working... It is a 48" T5 fixture for a 75G tank with soft corals and fish. In the meantime which would be the best two bulbs to have - 2 10,000k daylight bulbs or 1 of those and 1 actinic or other combo?
thanks!

I'd do 1 of each.

That's going to look really white, do you have a blue+ (or similar) bulb to add some visible blue?

my actinic is blue so right now i have that and the 10000 daylight - one of each. i'm not sure how long i can go with just those two bulbs? and when i get a new fixture (not even sure which to get) should it again have 4 bulbs?

It depends what coral you have. I would just get LEDs.

If you search "Dimmable 165W LED" on ebay, theyre effective and will grow anything.

They're also cheap, which helps.

Sorry to ask, I know it's not my thread but - Is there a big difference between the 120W and the 165W?

No, the 165w is max power, but the LEDs are run at 2w so the actual output is the 110w
