I'm not meaning to hijack this thread but I have similar question regarding lighting. I have an established 55 gal and currently run 2 x 65 CF 11 hours per day. CO2 is pressurized and I'm dosing EI. Would there be any benefit or detriment to having a 4 hour noonday burst using 4 x 65 while staying with the 2 x 65 for the rest of the lighting period?
