FROG^® Filter Mate^®

Julie C. Nichols - August 29, 2020

I have a large Inground fiberglass 1174 gallon 12 person spa. I had owned pools before but never a spa and finding any maintenance guidance for a spa that large is practically non existent. My chemical usage (to me) was very high. I have an external filter and 3 pumps similar to a pool setup. I use a bromine floater that I had to keep filling frequently as well as adding PH increaser, calcium and non chlorine MPS shock 2-3 times A WEEK. I was searching for something to help lower and more evenly balance the chemical swings when I learned about the Frog products. While Frog spa products are tested up to only 600 gallon spas, they were very helpful in working with me to fine tune the best fit for my spa. I decided to use the frog filter mate and expect to change it more frequently than the recommended 4 months due to the size of my spa. It’s now been almost 2 months and from the moment I installed the filtermate in my canister filter, my chemical usage has significantly decreased (way more than Frog advertises)! The bromine tabs in the floater last 3-4 times longer, I have not had to add the MPS shock more than once every couple of weeks. The PH increaser is now once every couple of weeks and I have only added calcium once. I live in Texas and with 90-100 degree heat in August, it was a true test for the mineral sanitizer stick. To my knowledge there is not a test that can tell when it stops working and needs to be replaced but knowing what my prior chemical usage was compared to now, I’m sure I will know. I am sold on the filtermate and will use this system for any pool/spa I have in the future.

I just got the Frog ease for my hot tub. When I put it in. it floats on its side. Is that ok?

Are you saying you must SHOCK your spa to activate the FROG ? Is that simply bringing the chlorine level to 3 ppm. or higher ?

Hello Sarah, We have been using the Frog system now for about 2 years. Not really sure of its effectiveness but our dealer said it’s really GOOD. I use chlorine, is it possible to remove the Frog for a period of about 8-12 hours while I performing routine cleaning, then reinsert? Does it lose its effectiveness out of the water for that period?
