Hi all,
New tub six weeks in. Tested daily (for my own education) with Taylor drop kit. Using nature2, has Ozone and UV, Spa marvel and maintain a daily chlorine level of 1-3ppm (1/2 tbsp per bather per hour). MPS weekly or twice weekly when heavily used. Free Chlorine and Total Chlorine are in lockstep. Ph is rock solid at 7.4. Alkalinity is 120. Prefilter is swapped out and washed weekly. Filter is sprayed weekly, swapped out and soaked monthly. All good so far.
Water is clear. Water stays clear without jets on low. Full jets and full air produces a slight foam that dissipates quickly but produces what appears to be slight oil slicks. MPS shock doesn’t change this. SuperChlorination didn’t either. Total dissolved solids are only at ~750ppm.
So any idea about how much foam is normal and if some oil is uneradicable? Thought?
