Evans 55 slice of the ocean

[Nebthet]

Hey.. I have five lights hung over my tak, but only three of them are on at ay one tome. I could go with a fourth if I wanted to to have max tank coverage.
If you go with a 36 inch tank, I would say 5-7 par30/38 bulbs
or for the 48 inch tank, 6-8 bulbs.

You could also try the Vertex leds. One of those with a two bulb t5 actinic would work.
