I took my water in for a reading as i had no chlorine ahowing on my test strip. My pool was open last year and I had no trouble keeping my numbers and balance and up until the last week I've had no trouble this year. When I took my water and they told me to put in 11 and a half pounds of balance Pak 100 and 11 one-pound packages of ahock and 2 pounds of low and slow... I took their word for it and I hope I haven't screwed up my pool totally. I put all of this in last night over about a three-hour period and even though I pre dissolved it all in water first there just seems to be a lot of stuff suspended in the water and I can't even see the bottom anymore. I've never experienced this type of thing so I don't know if this is normal or not but I'm going to watch it for a couple of days and if it becomes necessary I will likely just drain it and start over using y'all's recommendations. Either way I will be switching to your way of doing things as I learn and read more...good news is that we got our deck built finally!
