Let that spraybar splash the water's surface real good. Can never have too much of that, IMO.
My toddler got a hold of the timer that runs the CO2 solenoid and it was running full time without my knowledge a while back. Water was foggy, plants were bubbling like crazy, yet no deaths or fish freak outs. It was the spraybar that held down the fort!
And yes, he got popped on the behind for that little caper. Told the tyke a hundred times to "stay outta there!"
