Frog system at its best price! If you have the internal system, like I do, you may have some extra parts. The cartridges are identical, but you save at least $10 compared to purchasing a four-pack of cartridges.
In 2009, we used this system in our traditional hot tub and it was fantastic. 2012, so we figured we'd give it a shot with our inflatable, and it worked out beautifully! It's perfect now that we've gotten the settings right the second time; we don't need any additional bromine and have never used shock.
This newer formula has a significantly reduced chemical odor compared to the previous one.
It is beneficial to have a fair price.
We've set it to the smallest disbursement possible. To keep the levels low, we have to take it out every few days. I'm sure it's just the size of our hot tub that's causing the problem.
