Just purchased a home with a pool at the end of last fall. I've been keeping it looking great all season thanks to a lot of the resources available on this site. I'm still relatively new to this, but have a basic understanding of water chemistry, DE Filters, etc. It took me a little while to get the pool cleared up but I SLAM'd when I opened it, but I haven't really had any other issues all season. A little bit of algae growth here and there, but the pool has been crystal clear. I brought a sample to the pool store just after I opened the pool to get the chemistry dialed in. I've been using test strips since then, but realize I need to invest in a real test kit.

My biggest question has been regarding Chlorine and Chlorine usage. I feel like I've been going through a ton of it. I'm putting 2 bags of Super Shock in every 5-7 days to maintain my chlorine level. CYA seems to be fairly level, but I have had to add a little bit here and there. All other chemistry seems to be in line, and I haven't had to add much of anything. I'm just surprised that some weeks my chlorine levels drop to almost zero within 5-6 days. We've had some heavy storms lately, but it was very dry in May and the beginning of June. The pool doesn't get a ton of sunlight, and I haven't been heating it at all. Is this normal? I see many people saying that their chlorine levels will stay consistent over a week or more. As long as I keep adding the Super Shock the pool stays perfect, but if I try to go 7-10 days it starts to get hazy and I'll get some algae growth on the walls.
I purchased a bunch of 3" tablets early in the season at the recommendation of the previous owner. I filled the feeder back in May and they have barely dissolved at all, even with the feeder set on 9. I'm starting to wonder if this is even working as it doesn't seem to be putting much if any chlorine into the pool. I figured I would have to fill it a few times over the season, but at this point they are looking like they will last all season. Is it possible that it isn't working at all, or maybe the inlet hose is plugged?
I'm about to purchase another 24 bags of Super Shock or a bulk bucket, and can't help but feel like I am going through too much Chlorine. Any thoughts or suggestions?
