I'm helping a friend with his tank. He has a 90g with 4 vho retrofitted with an icecap 660. The tank is softies and LPS. He need to replace the bulbs, what should be used? Thanks.
I would do 2 UVL Super Actinics 1 UVL 75/25 and 1 UVL Actinic White (12k) OR 3 UVL Super Actinics and 1 Actinic White (12k) Those should make the colors pop as well as provide good growth. I always a 3:1 Actinic to white with my T-5s. I get good growth and great color.
If your buddy wants to save a few bucks. I have 4 new 48inch VHO bulbs I wont be using if he wants. They are 2 blue and 2 white. I bought them at $10 each so he can have the same deal. They were a adeal at $10 a piece so I bought 2 sets but have since sold the setup and kept the extra bulbs.
