Hey there. I had this problem before my last drain as well, was hoping to get some help here. Refilled about a week or two ago. I have ozone, but it might need replacing, I'm testing soon. I'm using test strips - I know they aren't great, but they're all I've got for now. I've been using Leisure Time. I totally drained the tub, did a line flush, everything, then refilled. I have some Leisure Time Brominating Granular (Sodium dichloro-s-triazinetrione, anhydrous: 84.15%, Sodium Brominde: 14.7%, Other Ingredients: 1.15%) as well as Reserve (32% Sodium Bromide) - when I shock it with Renew (Potassium Peroxymonosulfate: 32.18%,), nothing seems to happen - I can't maintain a Br level to save my life. I just added some Granulated a few days ago and some shock, and verified that I had a level (about 3ppm), but it was gone by the next day. Water is clear and looks fine. I can smell a bit of Bromine right now, but the level comes out to zero. Tub was used once and seemed to maintain its levels beforehand. I over did it a bit and used a smidge of chlorine neutralizer weeks ago as well as the sun to bring it down from 10ppm to 5ppm. I don't have a floater as I was going to just supplement the levels once a week - I do have bromide tablets I can put in a floater if need be. Not sure what I'm doing wrong, any insight appreciated. Thanks!
