Moved in to a new place 2 weeks ago and with all the stuff to do around the house the pool did not get my attention at first, so a little bit of mustard algae popped up. Grew up around pools, so know the basics and when there is trouble brewing. We had a basic test kit and there was very little chlorine in the pool. Reading up here (thanks all!) I ordered the TF-100 immediately. But, before it came I tossed the chlorine pucks out and put some bleach in to hopefully stop the algae (along with a ton of brush downs). Chlorine, running the filter, and brushing took care of the algae and I quickly got to the point where I wasn't losing any chlorine overnight. It has been great for a few days now.
Got the test kit and did a full test last night:
Based on that I added the pool math number for bleach last night. This morning I tested chlorine again and it was spot-on. Correct me if I am wrong, but the only thing I need to address is the calcium, right?
Love doing things myself, cutting out a pool man makes me happy. Thanks to the contributors here all my questions have been addressed in old threads, a tremendous resource!
