Yeah, am just waiting for someone to report they are going back to incandescent, with some of those blue covered bulbs. Bet the corals will really look nice. And bonus, can throw away all your heaters...

My corals are doing better now that I have enough fish poop to feed them
I'm not concerned about killing beneficial bacteria in the water column, and the flow rate is only 30% of my sump flow. It keeps my chiller internals clean and does keep my water clear
Maybe down the road I'll try turning it off for awhile and see what happens, but I wouldn't want to find my chiller became plugged with critters

I've heard about this beer dosing trend but, funny thing, everytime I think to try it the box is empty

Well, if it is any help to know, my chiller has been running steady for almost 14 years now, and no signs of plugging or losing effectiveness. And no UV.

That's good to know. Thanks
I'll PM you as the rest isn't thread relevent
