I love this product! Every morning I have a chemical readout with suggestions in case a measurement is too high or low. I alternate cassettes, using C2 for 3 months then C5 for one month. Seems to work well and helps me be aware of what is going on with the pool. I just started about 6 months ago and so far I feel I get enough information. I was able to fire the inconsistent pool guy and now the pool has never looked better! I got this!
