I figured 'Splash-Less' meant an improved bottle, but the bleach is like a syrup, and causes major foaming in the spa. The label otherwise looks just like the other Chloroxs, says "regular" and "concentrated". When I finally looked, the ingredients say Sodium Hypochlorite and Sodium Hydroxide...

I've learned how to lower TA by adding acid, then aerating to bring the pH back up. I understand that with normal use the pH will rise naturally so I've needed to add a little muriatic acid almost daily keeping pH close to 7.5 (or slightly below at times). I recently finished using Dichlor...

I'm wondering how regular users of hot tubs, kept outdoors in winter up North, manage their heat/cool down cycle most efficiently. Our tub is new, a basic model but spray insulated to current industry standards (or to Nordic's standards) with a nice fitting cover. My wife and I soak most days...

I just refilled my 250 gal hot tub, our water is quite high in TA (tests about 220ppm) but neutral. I understand the logic behind lowering the pH to 7.2 to lower TA but 'aeration' is not an option to help raise the pH back up. (It's too cold here to run the tub with the cover off.) Should I...

I'm switching over from Pristine Blue (copper) and after-use shock with Dichlor to the TFP system with BBB for my 250 gal hot tub. The tub is currently quite clear and clean, getting almost daily use. I've been reviewing 'Pool School' recommendations. Playing with the 'pool calculator' by...

Hi. I just bought a 250gal hot tub and filled it with my hard but very good well water. Using 'Instatest strips' the alkalinity is in the 180+ range. As directed I've been adding pH decreaser (sodium bisulfate, " Proteam Spa pH Decreaser") by the tablespoon dissolved in water for two days...
