FROGReplacement Mineral Reservoir for use with Pool FROG Model 6100 Cycler - Prefilled Mineral Cartridge for Quick & Easy Pool Sanitization

No algae, hardness or discoloration. I used traceg chlorine but not necessary... keep ph balance and pool crystal all season

does the job, great price, fast shipping!

I have a 9500 gal. pool this conditions the water for 3-4 months makes it feel like softened water.

Love my frog system

Use this product every year in our 24' above ground pool. Totally satisfied with it's results.

Works great. I've had the Frog system on my pool for around 10 years, never having any problems. Requires very little chlorine using this.

I've been using the frog system for 15 yrs and have always had crisp clean pool water. The price for the cartridge seems to be holding steady over the past few years. The only concern this time is that the cartridge only seems half full of the active minerals. Maybe it's my imagination so we'll see if it lasts the season.

I can't express enough how wonderful this thing is. When my wife and I installed our above ground pool we decided to go with the pool frog chlorine and mineral system after reading the reviews. I have to say it's the best decision I've made with our pool. There's no down time trying to fix the chemicals, no cloudiness, no algae ..just a perfectly crystal clear pool year after year. Instead of spending all my time trying to balance the pool, I get to spend my time enjoying the pool and lounging around in it. I'll go change the chlorine pak every 3 weeks and that's about it aside from vacuuming the pool. I do shock it once a month too. It's as simple as that. Never worry about it getting cloudy or out of wack. I hear my colleagues complain about their pool all the time but not me. It's all due to the pool frog system. Highly recommend it!!
