I am new to posting, but have been doing lots of reading. I started my own pool care a week ago. I have an 18,000 gallon in ground chlorine pool. After canceling my pool service, I bought a Taylor K2005 test kit and went to work. After draining 3' of water out of my pool due to high conditioner and CH levels, I finally got everything in balance. However, I have algae growing in several areas and seem to have sand on the bottom which I'm thinking may be algae as well. I broke down my DE filter last weekend and cleaned and inspected all the panels. No rips or tears, so there should be no DE coming back into the pool. And I haven't seen any coming through the jets. So now that my water is clear (way more so than when my pool guy was doing it), I need to get this algae gone. I'm going to test now and will post my levels shortly.
Any feedback is greatly appreciated!
Just tested my levels and they are as follows:
FC - 2ppm
TC - 2ppm
CC - 0ppm
I can't seem to maintain chlorine levels. I tested chlorine on Thursday evening and CC was 0, just like now. I added a 3" tablet to the skimmer basket and one to the floater. As well as adding 120 oz of bleach per the pool calculator. We left town that night, so no one has been in the pool. We returned home yesterday and this morning was the first time I've tested it. So, after a few days, my chlorine is back down again.
