hi all.
I start my second project about 2 months ago.
This is 90 gal tank , it is a DIY project.
i need only to paint the hood and put plywood on stand.
Inside hood i have installation for 2 bulbs T8 , but i don't know what kind of bulbs to buy , i really want to see the beautiful color of mbuna .
this is my tank now :

Use 6700k bulb with a 10,000k. The blue makes the blues pop and the daylight brings out other colors. You'll also get some algae growth which the mbuna's will enjoy.
