Venams Posted May 23, 2015 Report Share Posted May 23, 2015 I've recently changed the water in my hot tub, balanced the water to following parameters: PH=7.9 TA= 80 Borate = 50ppm Temp = 97 Normally I have sparkling water with no cloudiness at all with TA about 50 and PH near 7.5 My PH has risen a bit along with the TA but it still seems within range. Problem is the water is not super clear like it has been and there is a slight cloudiness to it. No smell at all. I used dichlor the first week and have been on the Clorox bleach since then keeping sanitizer level at about 3-5ppm I rinsed the filter (very clean and sign of dirt especially since tub has only been used twice since fresh fill) and tried using SpaGuard Water Clarifier. NO CHANGE: Rinsed the filter again and used Sparkle-X by Nature's Way: NO CHANGE. Rinsed filter after this as well. I'm stumped. Anyone have any suggestions for a way to clear the slight cloudiness up? Quote Link to comment Share on other sites More sharing options...
chem geek Posted May 25, 2015 Report Share Posted May 25, 2015 What is your Calcium Hardness (CH)? If it's on the high side, then the higher TA and pH along with hotter water temperature could lead to calcium carbonate scaling or precipitation. If you lower the pH and it clears up then that is probably what it is and you should just get your TA lowered again (via acid addition with aeration) so your pH won't rise as much.
