Switching Bulbs/Algae
I've been using the same 14k MH lights for about 10 months. Today I switched from 14k to 10k bulbs. Should I expect any kind of algae bloom?

no less light would make it harder for algae to produce it self

Is it really "less" light, or just a different spectrum? 10k is more white than 14k, which is white/blue. Both are still 400w.
