    Abandoned Pool - Suggestions Please

    Actually, I believe that Suncast products are made in USA. Keter products are the ones made in Israel. At least that is true for the storage sheds I have for those two brands. One thing I will say about Suncast is that their customer service is excellent. I moved an 8x8 storage shed from one...

    Testing pH with high FC?

    Why not use a pH meter as someone mentioned earlier? https://tftestkits.net/pH-Meter-p95.html Mine works well and as long as I wait for the numbers to stabilize, gives me consistent readings.

    Drop and swirl, or drop drop drop drop drop and swirl

    It seems like what you are doing would be fine. Consider saving up for the SpeedStir, though. It's definitely the way to go--as others have already said.

    Wiring a pump and salt chlorine generator into a WiFi timer

    Can you take a picture of the current wiring on the inside of your WiOn box?

    Facts and opinions please. Salt vs Chlorine?

    Kids are perfect salt mixing tools. I first added salt when they were in the pool and they freaked out until I told them it was okay. The next thing I knew they wanted me to add more. They liked the feel of the salt on their feet and said that it felt cool. Endothermic reaction of the salt...

    Buying older home and want to upgrade pool controls including SWG

    I'm not a chemist, but you need sodium chloride (NaCl) in the proper concentration for the SWCG to work. The system uses the sodium and the chlorine in the salt to essentially create sodium hypochlorite, NaOCl (aka bleach). The chemical formula doesn't work with potassium chloride (KCl). The...

    Should I add a SWG??

    No harm in adding salt up to the middle or so of the range that your SWCG needs. Don't add the calculated amount all at once. Inch up on it for a few days to make sure you don't overdo it with the salt. I ended needing two fewer bags than I calculated, for some reason. Probably had to do...

    Improving accuracy and repeatability in FAS-DPD tests

    I definitely agree on the SpeedStir--it makes testing fun, sort of. On the SampleSizer, though, I have resisted buying one because I can't bring myself to spend $22 on a piece of aluminum. After a bit of research on how to use it, I realized it also forces you to use the specific Taylor...

    PVC repair help needed

    ...and a piece of masking tape wrapped around as a guide to make sure you are cutting straight. A power miter saw or band saw is handy for cutting the new pieces to length if you have one.

    Sand filter let's silt through? Alternative media?

    I'm using Fiber Clear cellulose filter media instead of DE in my sand filter. It's biodegradable and non-carcinogenic (or so they say). You add enough for your filter pressure to go up by about 1psi from freshly backwashed. I've been using it since I SLAM'd, so I don't know if it's what...

    Normal sand filter differential?

    I've been using Fiber Clear cellulose filter media instead of DE in my sand filter. You can get a 3lb bag for less than $20. Biodegradable and not carcinogenic. Adding either of those may increase your filter pressure slightly. I add about a cup and the pressure goes up by about 1psi.

    White, gritty, substance?

    Yes. Also strips as well as pool store tests are notoriously inaccurate. You should consider investing in a Taylor K-2006 or Tftestkits TF-100 test kit. The color change is much more obvious than with the typical--what shade of yellow is that?--type of test. You can also get an electronic pH...

    Normal sand filter differential?

    Yes, a SLAM requires patience, especially when everyone around you thinks you are crazy for putting all that chlorine in the pool.

    Normal sand filter differential?

    It depends on your flow rate (how fast the pump is running). My filter pressure is 17psi @3000rpm when freshly backwashed. I have determined I need to backwash when it reaches 21psi (~25% increase in pressure). Now that everything is working well with my pool, I should only need to backwash...

    DPD Powder

    I use the light on the SpeedStir to help determine the last drop. There will be a very slight pink tinge left and one more drop removes it. I do not subtract that last drop. It sounds like you would go one more drop to make sure there is no further change. If you do that, how does it impact...

    DPD Powder

    The tftestkits.net instructions that came with my TF-100 kit do not even mention the 25ml test--only the 10ml, so now I see that this comes from the Taylor kit instructions. For the 10ml test, I follow the tftestkits instructions, which is one slightly rounded scoop of powder. So, I have never...

    Lowest RPM that will activate Hayward Chlorinator…..

    In my case, after priming at a high speed, the SWCG would work at 1600 rpm--or so I thought. After a while, the "No Flow" light would come on and the SWCG would stop generating. I increased to 2000 rpm and now the SWCG will work for the full 10.5 hours I have the pump set to run at that speed...

    Should I add a SWG??

    If the low speed on your pump provides enough flow for the SWCG to turn on, then it will generate chlorine whenever the pump is on. If that's the case you might be able to reduce the time you are running it on HIGH and increase the time on LOW to save on electricity. In fact, you can probably...

    CircuPool RJ-60 vs. AutoPilot Dig 220 PPC4

    I do not know where the CircuPool units are manufactured. There was no indication on the box or the unit itself for my CORE-55. I saw another post where someone said they were manufactured in Australia, but I think that is unsubstantiated.

    Should I add a SWG??

    Why do you think pool builders are so against SWCGs? I could understand a pool service company being against it since it takes away chemical sales, but not builders. This seems to be a common occurrence. ??? Regarding the conversion to a salt pool, people will probably notice that the water...

    Looking to replace SWG

    The CORE-55 is simpler to install because the flow switch and control panel are built into the unit. The RJ60+ is a little more complicated to install because it requires a separate flow switch to be plumbed in, and the control unit needs to be mounted somewhere. It provides a bit more...

    Wiring a SWG with VS pump

    If there is no water in the cell, there is nothing to make gases. The cell creates hydrogen gas as a byproduct of chlorine generation, and if no water is there to provide the hydrogen ions, then no gas should be produced. The SWCG has sensors in addition to the flow sensor, such as the "low...

    CircuPool RJ-60 vs. AutoPilot Dig 220 PPC4

    Besides the longer warranty of the CircuPool unit, it's also meant for bigger pools, so the cell should last longer. Since Discount Salt Pools sells both, you could ask them for a recommendation. For what it's worth, I recently installed a CircuPool SWCG (a different model though) and I'm...

    SWG selection and installation questions

    Instead of using a current sensing relay (CSR), has anyone considered using a pressure switch on the filter head to detect when the pump is running? A relay would still be needed in my case, since I only have 220VAC and no Neutral wire available. If I use a relay to switch the two hot wires...

    Oversizing a new SWG system

    Good point. If I run my SWCG at 100% instead of 75%, I can theoretically reduce pump run time by 3 hours a day. At 375W that is a savings of 1125 kWh or about $0.25 savings per day at my hyper-inflated California electricity rates. I'll give it a try.

    Oversizing a new SWG system

    The SWCG uses less electricity than the pump typically (depending on the speed), so you may want to consider reducing pump run time further and increase SWCG output to make up for it. Even though the SWCG is run at a higher output %, you are running it for less time, so the wear and tear on the...

    SWG advice - my first post

    A corded jigsaw is great, but even a hand hacksaw works fine. It just takes a little longer. Use a sharpie to mark the cut to make sure you are going straight. If there is paint on the existing piping, thoroughly scrape it off where the new fittings will be glued to make sure you get a good bond.

    CIRCUPOOL Core SWCG's

    Here's an update on my CircuPool CORE-55 SWCG installation. I am a relatively new pool owner (less than 1.5 years) and this is my first SWCG. Although I could have mounted it vertically, I didn't want to have the display sideways, so I re-plumbed a bit to install it horizontally. It was...

    Question on VS Pump and SWCG - "No Flow"

    I wish I could run my SWCG at that low of speed to save on electricity use. The problem is that I have a very slow buildup of air in the pump over time that eventually migrates to the SWCG and shuts off the internal flow sensor. This must be due to a small suction side air leak that I haven't...
