MH hours


Recommended Posts

I'm running my MHs 9-6 (actinics 8-8). Do you think it'd be OK to just run them 10-5? My chiller's working overtime, I'm having a titch of an algae issue (not bad but annoying), and I'm not sure if my SPS require that many hrs. I'm running three 250W 10Ks, and I have the SPS in the top 12" of the tank (acro, mille, seriato, monti).


What're you guys with some SPS doing, as far as hours-per-day?
