Prorocentrum Dinos - Beat in less than 2-weeks

Sounds good, I'm slowly reducing my hours now, already had the same bulbs you do too, and the XHO. Going to try doing what you did although my infestation is a little worse right now. Thank you for the help.

I don’t think you need to go slow to reduce the hours. But do go slow when you increase them.
