Sufficient light for SPS ?

[Marco.Polo]

Hey guys, so i'm not sure if i'm going with T5'S or with Metal halide + T5.

I know that with metal halide the growth is better, but i'm also looking to save money with electricity bill.

For 60cm or 55cm height, will 6 T5 High quality bulb will be enough? (Such as giessemann or ATI)?

Waiting for your appreciated answer! :mixed:

how is wide tank?

20" -->6 bulb
24" --> 8 bulbs
30"---> 10 bulbs

and more..

No more than 20", the question is, the height is not important?
I mean does 6 or 8 does not effect of the light to the depth?

Imho 39w are good until 24 depth.. 54 can used until 30 and 80 over
