I'm going through the procedure Vinny reccomended for refilling a tub that has been unused/drained for months. I filled it, put a cup of dichlor in, let it run for 2 hours and let it sit for 12 hours.
I'm getting ready to drain it again, and got a bottle of Swirl Away. It said to take the filter cartridges out... and I did. It said add 250 ml and run pump for 1 hour with no air. I added the swirl away and started up the pumps with the air controls turned off and got just a huge amount of foam. If I let this run for 1 hour, I will have foam trying to take over the backyard. What did I do wrong?
