OK. Thanks. Why do you ask if it is below 100? Using my CYA test, it looks to be greater than 90; but some of the markings on the sample tube have rubbed off, so it's my best guess. I am draining the pool now and will use your 2/3rds guidance.

My CYA level (>90) appears to be interfering with my algae control. I understand that to reduce my CYA level, I have to pump down my pool and add fresh water. Can someone provide guidance on how much old water to remove and replace? My pool is 16 x 32 and has about 21,000 gallons. Thanks Bob

Thanks. I was concerned that it might be contributing to my algae problem. Looks like I haven't been able to stick to the SLAM process. It seems like I've had my chlorine levels between 15 and 20 ppm all summer, and I still have an algae problem. Bob

We've had a lot of rain over the last few days and it's been hard to keep up with the chemistry. It looks like I may have it under control, but I am concerned about what someone said about my use of regular Chlorox bleach with the Clormax additive. I just bought liquid shock from my local...

OK on the tabs. I will stop using them. I have the TFP test kit so I can monitor the FC and CC levels. Thanks. Bob - - - Updated - - - Now I see why my CYA levels have been increasing. I will stop with the 3" tabs and look for another source of liquid chlorine. In the past, I was able to...

I just checked and the Chlorox bleach I am using has the "Cloromax" technology. Could this be the reason I can't get rid of the algae? In the meantime, I will look for another source of chlorine. Thanks. Bob

I checked the 3" tabs and they are also made by Chlorox. I have a chlorine in-line feeder which I thought I needed to keep filled with the 3" tabs. No? Please advise. - - - Updated - - - I will check the Chlorox bleach I'm using. It's convenient because I can pick it up at Costco for...

Thanks. - - - Updated - - - I've been brushing it each time I add chlorine to shock levels. - - - Updated - - - I am using liquid Chlorox (6.05%) bleach. I am using 3" tabs from Costco. I don't know why my CYA seems to creep upwards.

I've been having trouble this summer keeping the algae under control. It's been very hot and humid here on Long Island this summer and wonder if others are having trouble as well. I have been monitoring my CYA levels, which seem to keep creeping upwards. I have lowered the pool levels to the...

My sand filter is a new Hayward S244. I used the recommended sand (#20 silica) which I purchased from my local pool supplier, who said this is the sand used by all the local pool contractors. I backwashed the sand for 5 minutes before filtering and ran it to rinse afterwards. The only thing I...

Well I've been battling this teal green and cloudy pool all summer. I have been maintaining a FC level of at least 12 as per a CYA of 25 since the middle of July, and I still haven't cleared it up. The latest observation was when I turned up the speed from low to full throttle of my Hayward...

I added some DE (1 cup total) and saw the pressure go up about 2 PSI. I'll keep my eye on it through the day to see if things improve. Any comments on my earlier post? Bob

OK, gotcha, Richard. The color has pretty much stayed the same milky blue, but the clarity has not improved in over a week. At 8:00 pm last night (7/23) here's what I measured: pH: 7.4 CYA: 35 Alk: 90 FC: 10 CC: 0.5 TC: 10.5 I then added 1 gal 8.25% chlorox. At 10:30 pm (7/23): FC 16.0 CC: .5...

I'm confused...how is 1.0 ppm CC high? One person says my chlorine levels are too high and I am wasting my money on Chlorox. Now you suggest by your comment that I need to add more chlorine to get the CC down. What am I missing on the chlorine? Regarding the clarity, there's nothing more I can...

Is anyone out there? I posted this, this morning and no replies. Please help.
