    I switch to Frog System 6 months ago for my hot tub, The results are amazing! My chemicals are always balanced and the water is always crystal clear, No heavy bromine odor and it is so easy to do. No more fuss with measuring chemicals and constantly testing,

    I have an inline system on a hot tub. I can never get the levels correct using.the system alone. I always resort to.using.other products

    LOVE THIS PRODUCT!!! My husband and I were new hot tub owners and having issues with keeping the PH right in our unit. Friends of ours gave us the start up kit of SPA FROG and we are never looking back. Easy and works perfectly. Recommend this product to everyone!!!!!

    This is what makes having a spa worth it. I love things that are easy and simple and help take care of themselves. What a breakthrough! Putting in chemicals by hand every few days isn’t worth having a spa after a while.

      The bubbles are not coming from the Spa FROG Floating System. If you have a lot of bubbles or foaming it’s coming from body oils in the water that react to the natural alkalinity and aeration in the spa causing foaming.

      The best way to take care of foaming is to prevent it by reducing body oils in spa, avoiding headrest cleaners contact with water, and maintaining a low calcium level of around 150ppm.

      Hope that helps,

    I am having trouble with my water quality-I am using the spa frog system, but the ph tends to run low as does the chlorine and free chlorine levels. Does anyone have any ideas for me on what to do?

    1. Sarah Miller

      Thanks for your comments.

      Your bromine levels should be between 1-2ppm. If below, turn your cartridge up 1 setting. Your PH levels should be between 7.2-7.8. If they’re low your Alkalinity is likely low. Since Alkalinity is a measure of your waters ability to control PH begin by increasing your Alkalinity to between 80-180ppm. Your PH will rise as you increase Alkalinity and may fall into the correct range.

    I love the product. Switched to it from a chlorine base system. So much easier. Question – We also have a swim spa with a capacity of 1500 gal. We are currently on a chlorine system. Can you recommend a bromine system for that capacity. My hot tub is doing so great I am hoping for my swim spa to do the same.

    first time hot tub owner just went through the cleaning process and now added your cleaning system and shocked it and then put the floating system in how long do I have to wait before me and my wife can use it for the first time? Thanks for your help
