High-light photoperiod

[roydooms]

Ok. I finally decided that I will add 2 more 65W-6700K bulbs. Total of 6 on a 125g tank. Making it a "high-light. I have a CO2 system and I dose ferts. How long of a photoperiod is the MINIMUM for this set up? Thanks.

I'd start with 6-7 and go from there. I definitely wouldn't go over 7.5 to begin with.

I really was thinking of turning the lights on for 6 hours but I wasn't sure if it's enough. Now I am. Thanks.
