Aussie Chris Posted February 27, 2022 Report Share Posted February 27, 2022 Just wanted to send a note of thanks for Waterbear's contributions to the forum. We've had a 7000 lt swim spa for a few years now and I've always struggled with water quality. Based on his posts this is what I have done... Cleaned filters and pipes Emptied the spa Refilled spa Bought a Lamotte ColorQ 2x PRO 7 testing kit Balanced Calcium Hardness Balanced pH and Alkalinity Added 260 grams Sodium Bromide (bought in the USA and shipped down under - not available here) Shocked with 500 ml Liquid Chlorine (12.5%) This morning, after adding the Sodium Bromide yesterday afternoon, the test results are as follows: Bromine = 6 ppm pH = 7.7 Alkalinity = 94 ppm Calcium Hardness = 190 Not perfect, but not too bad for an accountant playing with his new chemistry set. The Bromine and pH look a little high, but I'll test daily and see how it shifts. Moving forward my plan is: - Experiment with the bromine tablet dosage in a floater - Shock weekly with a cup (250 ml) of Liquid Chlorine Unless of course, Waterbear tells me otherwise... Thanks again, Chris 2 1 Quote Link to comment Share on other sites More sharing options...
