Been using spa frog mineral sticks for years! You can really tell the difference when one runs out and you replace- water feels so much nicer!
This is an extra filter for your filters. It's awesome for families. It slides inside the larger filter and gets replaced about every 3 months. This makes a big impact on keeping our tub balanced. Especially when we have extra neighbors kids & friends over. We cut down big time on all the other cleaning and balancing products. It's kinda pricey up front but saves us in a lot of products in the end.
great product for the price
I would definitely buy this item again!
I've used these in my spa for 20 years. They do a great job keeping my hot tub clean.
