LimeStone/ Paver Patios


New member
[FONT=&quot]What mix would you use to remove mold and algae from limestone patio, that will not kill grass or plants. My first thought is to pick up some snot from russ, mixed the 10% bleach and run through downstream injector but I am super nervous about killing any grass. I will be pulling out of a 50 gallon chem tank. Any suggestions will be greatly appreciated[/FONT]
