I have a generic 1.5 hp pool pump that has been installed for about 6.5 years. I run it about 6 hours a day for my 20,000 gallon pool and I try to keep the pressure at my cartridge filter no higher than about 12-13 pounds . Today, while putting chlorine in my pool, I thought I was hearing...

I helped my neighbor through a SLAM a couple of years ago. I tried to talk her into using TFP but she declined and went back to pucks. She asked for my help again recently because, of course, she was fighting an algae outbreak...one she couldn't beat. Now, unfortunately, her CYA is up to 110 (at...

One of the inputs to Pool Math is salt level. I do not have a salt water generator so I don't measure salt level. What is an average salt level for a non-SWG pool? I searched the site for an answer but couldn't fine one. I'm sure this question has been asked and answered before but I couldn't...

My pool is heated by the sun. Any opinions on whether more or fewer hours of pump run time will heat it up faster? Does turning over the warm water on the top and bringing up colder water below speed up the heating?

We survived Irma in good shape but the pool screen took some hits from the neighbor's broken tree tops and branches. Lots of debris in the pool and no power for the pump. We had boosted the chlorine but we took on a lot of water. I wanted to know if I can just manually stir in chlorine with the...

A friend (new member) has a TA of 170. I advised her to use the Pool Math calculator to determine how much baking soda to add to reduce it to 70. She said Pool Math didn't give her any amount of baking soda to add. Huh? So I went to the Pool Math calculator to see for myself. TA loaded...

I was doing my daily visual inspection of my pool and pool equipment. I reached down and touched my pump and it was hot. So hot that I could not leave my hand on it for more than a few seconds. All my plumbing was sweating like crazy because today was in the mid-70's but the humidity was 80+%...

FC 6.5 PH 7.5 TA 70 CH 250 Temp 76 CYA Apparently 0, according to TFP test kit Well, I guess we changed out more water during the hurricane rains than I thought. Recently, I have been adding more chlorine daily (2-2.5 ppm) to remain at my desired FC level of 6.5. That level was selected...

FOUND THE LEAK (I think) - see next post. I am getting air bubbles in the pump trap. I noticed a 2-3 weeks ago I was getting a few bubbles coming out of the pool jet closest to the pump at start-up (after the big burst of bubbles that is normal at start-up). When I noticed the bubbles were...

I just completed my first SLAM so now I'm the local expert! My next door neighbor was complaining of algae but luckily had not yet been to the pool store. I took my TF-100 over to see what was going on. I definitely saw algae and these are the numbers for their 20,000, concrete, in-ground pool...

Pool numbers at pre-SLAM, Thursday afternoon (5-12-2016) FC: 7.0 CC: 0.5 or less pH: 7.4 TA: 90 CH: 280 Temp: 76 degrees Thursday afternoon I decided to clean my filter cartridge because I noticed the pressure was up. It was completely green! Luckily, it easily washed off. I was surprised...

When we purchased the house, the seller said the pool had recently been refinished. The house was a foreclosure and was vacant for at least a year prior to being rehabbed. Our only experience has been with a vinyl liner pool (2001-2004) so I don't know what to expect with a concrete pool. We've...

Hello, We purchased our home about a year ago with an existing inground pool. The pool light did not work during one of the pre-purchase walkthroughs so we asked for it to be fixed. It was operating during our final walkthrough before closing and for awhile after we purchased the house. Our...

Someone suggested using hair nets in the skimmer basket in place of pool socks and I thought it was worth a try because I could buy 100 hair nets for about $6.00 on Amazon. That's really cheap compared to the cost of pool sock$. Yesterday my order of hairnets arrived and since we already have a...

Yesterday I added both CL and acid to my pool. This is what I posted yesterday on another thread regarding my readings prior to adding anything: FC 5.5 PH 8.0 TA 110 CYA ~60 These are my readings this morning: FC 10.0 CC 0 pH 7.5 CH 375 (Note - This is slightly elevated from where we...

Hello, My readings and actions today: FC 5.5 chlorine added to hit 7.0. Level was 7.0 on Wednesday. PH 8.0 acid added to hit 7.4 TA 110 CYA ~60 as far I can tell Cleaned my Hayward C1200e filter. Pressure went from 18 lbs before cleaning to 8 lbs right after...

Hello, We purchased a home in May 2015 with a concrete pool which I estimate to be about 20,000 gallons. I live in the Orlando area so the pool gets lots of sun during the summer. We installed a screened enclosure that was completed in September. We had finer mesh screen installed on the top...
