I use Cutrine plus to control filamentous algae as needed when conditions are not suitable for tilapia, or if tilapia are unavailable. It appears that if tilapia are readily available I could limit algae treatments to a single application in the spring and fall and be algae free. I have a very small 2'x5'patch of cattails growing out of a moist bare area between the limestone border and lawn. I don't mind a few and allow them to grow. I do cut off the flower spikes before the go to seed. They don't grow throught the geotextile fabric and limestone and can't compete in the lawn. This year, with excessively low water levels, some grasses have started to grow between the rocks that were below water level and have some silt between them. They are easily pulled or spot treated with a herbicide.
