We just moved into a house and have a inground fiberglass pool that is roughly 20,000 gallons. I just opened it and shocked it and it's looking good. I just came across this website/app and ordered the pro test kit. I have been running through all the information on here but couldn't find anything about in-line or floating chlorinator. My pool does not have an inline set up and when I opened it it had a floating chlorinator in it. Was that just for the winter or do I need it during the summer? Or do I just test regularly and add to the pool as needed. Thanks in advance for any advice. I am looking forward to diving in deeper and learning more.
