So easy yo use and my spa is crystal clear

soon i will be trying to get credit of some kind for a cover so ill be seeing how that goes

I like this product because it is fragrance free no chemical smell. It also makes the water crystal clean. Would recommend to anyone that does not like that chemical smell.

Very good products

Price was fair, shipped for free and a expident manner. Never having contacted this Merchant with being able to fulfill my order.

This product is excellent and will continue to use it in the future

I have been using the Spa Frog Mineral cartridge in my hot tub for 10 years. It has been a consistently good product and has kept my hot tub in chemical balance. I highly recommend the product.

these cartridges are easy to use but have gotten extremely expensive. I would love to find something else to use that isn’t so high priced.

I have been using the floating Frog Mineral & Bromine Cartridges for years. They are easy to use and help build confidence in a clean and healthy hot tub. Spa Depot is a dependable web store for all my hot tub needs!

Works great for Caldera spa

As described. Fast shipped. Nice business to deal with.

Sometimes I have driven over to a nearby store to get my hot tub supplies when I need them that day. The last few times I have gone there, they either didn't have what I needed and said they couldn't get it or I had to buy a box full of multiple items I didn't need that day. When I order from Spa Depot they usually have what I need and it arrives quickly when shipped to my home. There cartridges are so easy to use with my in-line cartridge holder! It helps keep my hot tub crystal clear!

Keeps my spa nice and clear...

Keeps my chemicals at the right level with very little effort from me.

They do the job in our older hot tub….

Use with Frog cartridge holder. Works great!

Works well with our hot tub, only thing is making the plastic around it easier to remove.

They say it lasts a month, it only lasts 2 weeks...the frog system is costing over $50..just the frog system...

It makes the water silky smooth. We have the floating container to keep both products floating around together. Does a great job.

I have been ordering spa chemicals and filters for the past six years. I have never had a problem with an incorrect item being shipped or the shipping process itself. I think their prices are competitive and would highly recommend buying from this company.

We use both the mineral and the yellow Frog cartridges together in a Frog holder in our spa. ..continuously. So much easier and better than balancing chemicals everyday!

things are a little expensive

Best price anywhere. Fast delivery too!

Great service

Have used these products for 5 years for our hot tub. For me, it is excellent.

These mineral cartridges are used in my hot tub. These are the same brand that was installed in the tub when it was delivered. I expect that they will perform exactly like the original cartridge, but at a lower cost to me.

This product arrived in a short timeframe and in excellent condition.

Easy, reasonably priced, shipped quickly

Hot tub chemicals

Service was fast. Easy to order. Only thing I would have liked to see was a few more products on the special buy one for a dollar.
