    Iron stains

    I have iron stains in my pool. At the beginning of the summer I did an absorbic acid treatment which got rid of the majority of the stains. The pool looked great. I added ProTeam Metal Magic throughout the summer and kept pH in check (mostly.) However, throughout the summer I could see the...

    Hayward Northstar pump - Help Putting back together

    We cannot get the motor (dry) section back together with the pump (wet) section. We took it apart to make sure the impeller was turning properly. All we did was take the diffuser off and then turn the impeller both ways. Since it did not have any debris there and it was turning we tried to...

    Pump not on!

    Yesterday my pool was working when I tested it. However, for the past month or so I have been feeling that the circulation has seemed a bit low. I even cleaned the cartridges bc I thought they may have been dirty therefore slowing the circulation. (Perhaps just bc I was wondering what I would...

    Confused about test results - red stains - could there by algae?

    Tuesday July 1 test results pH - 7.5 FC/TC = 4.0 CH = 250 TA = 70 CYA = 40-50 (I have been adding slowly) So we leave for vacation and I set the SWG for a super chlorinate on Wed July 2nd to run for 24 hrs. While we were away Hurricane Arthur left rain (1in) and dumped debris (leaves and...

    Replacing pressure gauge

    I noticed that my pressure gauge has moisture in it. It still works but I was thinking of replacing it with a glycerin filled one from this site. 1. It says freeze protected to -4F. I live in PA and it can get lower than that but not often or for extended periods of time. Should I not use...

    Increasing pH and CHL after AA treatment

    Tomorrow I am going to rebalance after an AA treatment. First, I have to do a complete set of tests. Then I understand that I have to increase pH to 7.2 and get TA into range using A&H washing soda. How often to I test pH? Hypothetically if I add 30 oz of wash how long do I wait before...

    Absorbic Acid Treatment - more AA or more sequestrant or more patience?

    I have some light stains on the sides from the water line at closing and black stains on the bottom. Today I did an AA treatment. I used 5 lbs of AA and 2Q of ProTeam Metal Magic. I do not have a circulate cycle or a backwash system so I'm just keeping the filter on 24/7. I sprinkled the...

    absorbic acid treatment and pH level

    I have a SWG pool and am going to do an absorbic acid treatment this week (have been waiting for Chlorine to go down). Per the treatment I understand that the pH should be 7.2 or lower, however, the SWG guidelines suggest 7.5-7.8 for maintenance. After ensuring metals are sequestered with the...

    General Slam FC question

    If you slam your SWG pool and are targeting a FC level of 4 but shock level of 24 with CYA=60, how does your FC get back down from 24 to 4? Does it stay high for a while and you turn off your SWG? Curious, as to how your pool returns to normal level.

    High phosphates and high chlorine

    FC = 7.5 (is this level unsafe?) CC= 0 All other levels acceptable. 1. I had my water tested at a pool store bc I wanted to know the metals and phosphates were 1000. Of course, they were trying to sell my PhosFree but I didn't bite. Should I add an algaecide? 2.Pool stores said nitrates were...

    How to lower chlorine?

    In the near future I am going to do an AA treatment. My chlorine is currently 5.0 with all other chemicals in balance. How do I lower chlorine prior to treatment? Should I turn off the SWG for a week or so? Is there a link anywhere detailing how much sequestrant to add after the treatment...

    Pool pipes - what are they?

    Attached are 2 photos of my pool and equipment. Can someone please tell me which pipes are which? They used to be labeled but the labels are mostly worn off. There are 2 Hayward north star pumps, the one on the left is for the pool filters and the right one is for the waterfall. I have 2...

    Stains on walls

    Stains are on the walls of pool where the water line was while it was closed. I rubbed a vitamin c tab on it and it disappeared. I saw the pool school article on how to do an absorbic acid treatment but I was wondering it an entire absorbic acid treatment is needed since the stains are new...

    Manual pool vacuum recommendations

    I have a Polaris 9300 robot that is in the shop. (FYI: apparently, you are not supposed to use the robot to get the fine particles off the bottom - it is for maintaining your pool only. Seems ridiculous to me to spend all that money...) As a backup I may purchase a manual vacuum that goes...

    New to testing pool

    I just received my TFP kit. I used it for the first time today. My pool has been open for 5 days. Today is the first day I tested it. It's a 21000 gal gunite salt water pool. I live in PA. I'm trying to follow the "Water Balance for SWGs" post but have a few questions related to salt and...

    dead frog

    A dead frog got underneath my skimmer basket and went down the pipe. It was about 2 inches long and 1 wide. Will this cause any problems? Where will he go? I have a 26K SWG cartridge pool/spa. Thanks.

    Do I need a new SWG?

    I'm new to TFP and this is the 2nd summer in this house with a pool. The pool is 22,000 gal saline pool with Goldline Hayward equipment. Pool is 7 years old. I do not know if the SWG has ever been replaced. The past few weeks I have been getting a low salt error. I've added salt and...
