i have a 1/10 acre pond that is spring fed --25 -30 gallon a minute that runs thru the pond --since losing my 3 willows for shade I nave had an algae problem ( new willows are growing ) i have a fountain i run 4-6 hrs a day . the ponds deepest point is 6ft . Should I use a bottom aerator if so what size pump and what kind of diffuser large or small bubbles . Seem life large bubbles would raise some of the muck that will then find it way out the drain --Any suggestions would be great

That shallow of a pond it isn't necessary.
