   We are getting a considerable amount of Bryozoans on the screens of our irrigation heads. This problem occurred in the 90's when the course was new, and the previous supt dripped chlorine into the wet well. Of course 20 years later the records are no where to be found.
   
   Anyone know the ppm needed to kill them, and ppm bent and poa can handle safely?

   For what it's worth, we use .05 PPM chlorine to strangle Zebra Mussel larvae. I believe the upper limit for bent grass tolerance of chlorine is 5 PPM. But don't hold me to it.

   I think it is more in the order of 140 ppm´s and then you need to let it dissipate into the air or pump it out to innocuous area. I organized a Bryozoan treatment for a very complicated water system in the Middle East.
   
   How much water does your wet well hold? Where are they coming from?

   My wet well holds about 1100 gallons.
   
   Our water source is a combination of effluent and creek water.
   
   I have been here 11 years without much of a problem. A new waste water plant was built about the same time. When the course was new it was a yearly problem. The original supt could not remember the ppm. He does remember using less than 5 gallons a night. At that time the system might have been pumping around 400,000 a day.
