I am currently running 4-96w (12k) CF's and 3-150w(10k) MH bulbs on my 180 gallon planted tank. The CF's are on about 14 hours and the MH's about 4 hours during the middle of the day. One of my MH's burnt out, so I am wondering if I should replace it with another 150w 10k or switch all three to 150w 6700 or 8000k? Which would be better for the plants?
Thanks.
Thanks.
