Leeboy Posted October 5, 2014 Report Share Posted October 5, 2014 I just returned home from working out of town last 5 days. Flipped open the hot tub cover and noticed my filter broke off at the base where it screws in. Pulled it out and unscrewed the base , and looking down some weird brown dots caught my eye on the edge of a seat. Before I left, I turns it down to 90 and shocked with spa gaurd bromine powder( mostly dichlor) filled the floater and closed the lid. Floater still some tablets in it. I don't have a taylor kit yet. So without adding any chemical yet , I used a bromine test strip and it looks fine to me. About 3 weeks ago, I did a aaah-some clean and bleach super clean. And I was maybe in two times since . Any Idea what the brown dots are? As soon as you touch them , they go away . Quote Link to comment Share on other sites More sharing options...
Dr. Spa Posted October 5, 2014 Report Share Posted October 5, 2014 Well water , or city water in the spa? Quote Link to comment Share on other sites More sharing options...
Leeboy Posted October 5, 2014 Author Report Share Posted October 5, 2014 I'm on city water. Could it be some left over of the brown gunk from the aaa-some ? Should I shock with straight dichlor ? Quote Link to comment Share on other sites More sharing options...
chem geek Posted October 8, 2014 Report Share Posted October 8, 2014 See if putting ascorbic acid (vitamin C) on it gets rid of the spot. If it does, then it may be iron in which case perhaps your fill water has iron in it. Quote Link to comment Share on other sites More sharing options...
Leeboy Posted October 8, 2014 Author Report Share Posted October 8, 2014 As soon as I touch it ever so lightly with a cloth , it's gone . I could probably wave the water really hard and they would blow away . I'll wipe em off and see if they come back . Ther only in that one area .

chem geek Posted October 8, 2014 Report Share Posted October 8, 2014 If they are removed that easily, then they should filter out. I don't know what they are. Quote Link to comment Share on other sites More sharing options...
Leeboy Posted October 9, 2014 Author Report Share Posted October 9, 2014 Wiped them off and almost have a smudge to them like "grease" Quote Link to comment Share on other sites More sharing options...
chem geek Posted October 9, 2014 Report Share Posted October 9, 2014 Well maybe they are like you say remnants of greases/oils dislodged by the Ahh-Some but not completely physically removed by the drain/refill. Quote Link to comment Share on other sites More sharing options...
