First of all, thanks for a great site!! I came across this site last summer after i experienced a fish kill in my pond due to the extreme heat/drought. I built an aeration system from the info i gleaned from this forum. So far it is working well. I ran it all winter but i am still experiencing an issue with murky water. I also seem to be experiencing early algae growth this year. In previous years i have used cutrine to try to keep the algae in check but not sure if i should use again this year. The labeling indicates not to treat more than 1/3 of the surface area at a time. Does anyone know if this will be a problem since i am running the aeration system 24/7? Didn't know if the increased water circulation will cause any problems. If anyone has any tips or suggestions for the water clarity/algae i would appreciate it.
