if i dont want to go reef.. ahhaahh just use regular light if only fish.. so yeah.. i think beginner should test with fish only tank for awhile...
hey i am thinking of painting my back wall white.. i think it would help reflect light.... and i assume it should be better for corals... and save electricity.. dont have to light up so much light..
what do you think??
