    Heater efficiency question.

    I have a Hayward pool heater, H400FD in my 10,500 gallon indoor pool. This is a very large heater and I installed it new in June of 2020. It has a safety feature that won't let the heater fire up unless the flow rate is above a certain level, around 2200 rpm (this is a good thing). I run the...

    Liquid chlorine price in Alaska

    I posted a price a few months ago for LC here in Alaska of $15.95 per gallon at Alaska Pure Water Products in Anchorage. At that time, it was the only source. I previously bought LC at Ace Hardware here in Homer for $7.99 but they stopped supplying us over a year ago due to the pandemic. I am...

    TA too high.

    I dumped all my pool water over the weekend, cleaned things up and refilled. I put in new chemicals and now my numbers are: FC 1.36 PH 7.26 TA 85-90 CH 200 ORP 740 Salt 50 CYA 0 I made a mistake about the TA of the tap water so I added too much baking soda and now I feel like the TA is too...

    Iron in carriage filters

    I have a Hayward Swim Clear filter and a Hayward 400k BTU heater. The heater has a safety feature where it won’t heat the water unless sufficient flow is in the system. For me, that’s 2250 rpm. Today the heater wouldn’t come on. This happened before and I called Hayward and they said my filter...

    Total Dissolved solids question.

    OK. So I drained the entire pool (10,500 gallons) on April 1, 2021 and refilled it. After balancing the pool chemicals to the usual levels, I checked the TDS with a hand-held unit I bought from Hanna Instruments. As of April 7, it was 402. I check it every few weeks or so and it has increased...

    Liquid Chlorine price.

    I finally found a source for Liquid chlorine here in Alaska. It's in 1 gallon jugs, 12.5%, 4 jugs per carton. I purchased 8 cartons yesterday and it will be delivered Friday. It's at Alaska Pure Water Products in Anchorage. It's sort of a pool store that will also deliver drinking water to...

    Running out of Liquid Chlorine.

    My pool uses about 1-½ to 2 gallons of 10% liquid chlorine per week. I currently use the HTH brand (10%) that I have always bought from Ace Hardware here in Homer, AK. I have 12 gallons left and I know that I will not be able to get more any time soon. I am afraid that I will have to switch...

    Iron question.

    OK. So I dumped all my water on Thursday, April 1. Cleaned things up on Friday and filled it back up by 2:30 Saturday. The water was a bit yellow, which it was when I first filled it last June. By Monday morning it was pretty clear but by yesterday it was TFP clear. See photo. Now my PVC pipes...

    Pool temperature and FC?

    I have an indoor, commercial, aquatic physical therapy pool in Homer, AK. I keep it at 95-96 degrees when clients are present. I have a question about whether or not I should increase the FC level because of increased temperature. This is an un-stabilized chlorine pool without CYA. The Phin...

    Question about anti-scale products.

    My 10,300-gallon pool has a nice blue "field tile" below the waterline but has a darker blue tile for the top 6." So the waterline is 4" from the top. I get some (not a lot) of white residue on the tiles above the waterline and I believe it is from the calcium in the water. I have been looking...

    ALK question.

    Here are 2 photos of my Taylor ALK test. The first is after 6 drops of R-0009 and the second is after 7 drops. The first photo doesn’t show it well, but there is a slight pink area at the lower half of the tube although the upper part is definitely still green. I have been reading this as 70 all...

    First time cleaning filters. Look OK?

    Hayward C3030. New 6 months ago. I took it apart per TFP guidelines. I hit the carts with a filter flosser. Lotsa dirty water went down the drain for 5-10 minutes. Emptied the tank and cleaned it all up. Put them back in and It’s back running now. Here are some before and after photos. Question...

    Interpreting lab report?

    I just received the report shown in the photo for testing my pool water. The lab simply said that the results were acceptable under the current State regs. I have these tests done once a month. I would like to know if an HPC of 4 is considered a low level of bacteria? I looked it up and it...

    Question about TDS

    I just purchased a TDS meter from Hanna Inst. Pretty easy to use and cost $52.00. I checked my fill water and it's about 86. My pool does not use CYA or SWG. The only chemicals I add on a regular basis are Chlorine and Muriatic acid. The TDS is consistently about 1050. The CH is 200, ALK...

    Can I use this to add water to my pool?

    When I set up the plumbing, I had them put in this tee with a hose bib so I could lower the water level in the Swim Clear filter when it was time to change out the cartridges. I now want to use this as a way to add make-up water to the pool. It usually requires an inch or two once a week...

    ORP question

    I just got my Hanna HI98121 yesterday along with bottles of calibration, cleaning and storage liquids. My pool is kept at 95 degrees and receives heavy use. They recommend that the PH function be calibrated every time I use it and they also say that after calibration, I should just put the...

    TA question.

    Not really a problem but just a question. I haven't added any baking soda to my pool in over 3 months, maybe more. FC is managed by adding 12.5% liquid chlorine with a Stenner Pump/tank combo (FC around 3-3.5 ppm). 15 gallons of liquid chlorine last me 2-2-1/2 months. I try to keep the PH...

    Liquid Chlorine cost?

    I am in Homer, AK and the closest place to buy 12.5% liquid chlorine is in Anchorage, 225 miles away. I called APUN yesterday (chemical supplier in Anch.) and he told me that if I brought my own container, which I have from another supplier, the cost to fill it up would be $78.00 for 15...

    SLAM question.

    Here are my numbers: FC - 1-1.5 ppm; PH - 7.5-7.6; ALK - 60; CH 200; CYA - 0; Salt -0. This is an indoor therapy pool kept at 95 degrees, 8 hours a day. I know, the TFP people think I should have 20+ CYA, but I just want to agree to disagree about this. My question is how often do you...

    I need help determining the correct FC level.

    I have been using the Lamotte Color Q pro since the pool opened in early June. It always gives me a reading for FC in the ballpark want: 1.5 to 2.0 ppm. I also have a Taylor K-2005 kit that uses the pink water color comparison test which I do not use because of the inaccuracy. So a few...

    Problem with Hayward Pool heater.

    I have a Hayward Pool and Spa heater (400K) Model H400FD. Natural Gas. It's used with an indoor Therapy Pool and the PT's and clients like the pool water temperature to be between 92-96 Degrees F. It has the typical Hayward red LED light that shows the temperature of the water running through...

    Anyone have an opinion about Acid Magic?

    I have recently switched from dry acid to muriatic acid for PH control in my pool. A person who has maintained the "High School Pool" here in my town (Homer, AK) told me that the Borough School District changed from MA to Acid Magic several years ago. I looked it up and it seems that the price...

    Lamotte v. Taylor.

    OK, so I bought the Lamotte #2086 Color Q Pro about a year ago but my pool wasn't finished until mi-June, 2020. At that time I bought all new chemicals for it. The color Q gave me very inaccurate readings for CH and I ended up putting in way too much Calcium chloride. So I bought a Taylor...

    Stenner pump/tank question.

    I'm just getting started. I am using a 15-gallon gray Stenner Pump/tank combo unit to add 12.5% chlorine solution to the pool. The tank will be indoors as this is an indoor pool. A couple of questions: 1. How long will the chlorine solution last in this container? The equipment room will be...

    Which is better? Tile or plaster?

    Construction is just getting underway for our new indoor therapy pool in Homer, AK. 12,500 gallons, 26' X 16' X 4'. I'm trying to decide if I should put in plaster or ceramic tile on the pool walls, bottom? If I go with tiles, I want to use epoxy grout. We have a very talented tile guy here...

    Never owned a pool before.

    I'm a new member. My life partner, Anette, is a Physical Therapist here in Homer, AK. She now "rents" time at a local health club in Homer for $165.00 per hour to provide aquatic PT. She also rents another building to hold exercise classes. So I have decided to build her a new indoor pool. It...
