DIY additional Fluorescent T5's lighting

[Reefkeeper_DR]

Hello I'm looking to add too or replace my zoomed T5 48" with a 6 or 4 bulb fixture I research fixtures Via, Lowe's and found some great fixtures but before anything I would first like to shear my experience with someone who has,

Should I go with 6 bulbs or 4 ?
Should I replace current fixture and use for parts?

I would appreciate your advice

I don't think lowes carries any t5 components.

I don't think lowes carries any t5 components.

Home Depot does though...

My lows have t5 tombstones and ballast no specifically but one that can support but just don't sell t5 bulbs

I think I want to threw two T8 with two T5 and a middle Led royal blue tsrip that comes in a fluorescent cassing

What you guys think?
