arnspa Posted October 24, 2013 Report Share Posted October 24, 2013 Our visitor did not wash the filters in our Masterspa H2X for many months. When I came to change them they were coated with a sort of green gel like stuff, see photo. This later dried to dry powder. Anyone know what causes this?

arnspa Posted October 31, 2013 Author Report Share Posted October 31, 2013 One week and no reply? Have our pros never seen this before? I might add the water was clear (1300 gals), the pH was very low. Quote Link to comment Share on other sites More sharing options...
waterbear Posted November 2, 2013 Report Share Posted November 2, 2013 the Ph was very low.Suspect that the green was from dissolved copper from the heat exchanger as a result of low pH for an extended time. the gel was probably just a buildup of gunk from not cleaning the filter and the disolved copper stained it green Quote Link to comment Share on other sites More sharing options...
