Hi everyone. Just opened my pool a week ago and the water was clear and I have all my chemicals balanced and in line except for my free chlorine. I continue to show low and can't seem to raise it. I will provide some true numbers tomorrow afternoon to hopefully help us figure out which direction to go. My main concern is the chlorine I'm using. I have always used 3 inch chlorine tabs in a floating dispenser with no real issues in my pool. I always liked the idea of having chlorine slowly dispensing into the pool so it doesn't drop off. I'm currently using Leslie's 3 inch jumbo tabs which are slow dissolving, but they seem like they are taking way longer than usual to dissolve. I have my floater open all the way with 3 tabs inside and it looks like they've hardly gone down in a week. By reading this site, I never knew CYA was directly impacted by granulated chlorine and tablets. My CYA looks good, but I'll give true numbers tomorrow. I'm thinking about possibly switching to liquid chlorine so I won't raise my CYA to high levels. I have never used liquid chlorine and I can get the 12% stuff from many pool stores in the area so that isn't a concern. Will the liquid chlorine bleach my vinyl liner because I definitely don't want that? I always run my pump daily for about 8 hours (usually from 10 am-6 pm) and then pull my solar cover on for the night to keep the warmth in the water. I know its recommended to add liquid chlorine in the evening but I really don't like running my pump overnight, especially since I ran it all morning and afternoon. Is it fine to add the liquid chlorine in the morning or late morning instead of evening and will it have any negative effects on my solar cover? I'm a newbie to the idea of liquid chlorine so any advice you can give me on the best way to use it would be appreciated. Am I running my pool pump the proper way too? Should I run it in the evening and not the middle of the day? Thanks and I'll post some water test numbers here tomorrow. I'm looking forward to getting this situation figured out.
