First off, I did a search on TFP and see that foamy water can be related to low CH or contaminants in the water. Neither of these apply to our pool though. My observation of foamy water is that when someone kicks or when I am mixing in the chems with my pool brush and skimming the top of the pool water, the water gets foam/bubbles on top and then they disappear after 10 seconds or so. We also had foamy water last year and I thought it might have been from the lower CH since we have a vinyl pool, but I raised the CH level last week to 200. Can metals in the water cause foaming. This is the one thing I have never tested for and we do have well water.
We only added algaecide back in November and when we opened the pool two weeks ago, the poolguy let the antifreeze go into the pool and said it will dissipate after a few days.
I am baffled.
My readings this am were
pH....7.8 (added 17oz MA to lower)
CYA...40 (we do not have our SWG operating yet. Plan to add the salt this w/e and will add more stabilizer to adjust between 60-80)
