    SWG Chlorine Generation too low

    Update: I ran an ONCGain test on Wednesday night with the pump on high speed. 10:39pm: 10ppm 7.5 hours @ 100% should generate 5.8ppm 6:10am, 13ppm This seems to confirm the other results.

    SWG Chlorine Generation too low

    Lol. So many bubbles to worry about. My SWG is now mount horizontally and I do get a small bubble at the end of the cell, after the end of the plates, in the small dome created before the transition from 2" to 1.5". I can't imagine that this could downrate the generator by >50%. Here's what...

    SWG Chlorine Generation too low

    I get a bubble in the pump lid when the skimmer sock is loaded up. With no resistance to suction flow, no air gets pulled in. Kids bouncing around in the pool also introduces air, but I can control for that.

    SWG Chlorine Generation too low

    Ah, I see what you're suggesting. Light dawns on Marblehead. I'll give that a shot tomorrow night when I have time in the morning to test before work.

    SWG Chlorine Generation too low

    I did run it all night. But I have no way of knowing whether generation stopped at any point because of low flow.

    SWG Chlorine Generation too low

    I know it was in Super CL all night because I had to turn it off in the morning to allow it to mix for 20 minutes or so before testing. I checked the diagnostics during two consecutive cycles on Saturday. Unfortunately, only the 2nd saved in my notes. My recollection is that the other one was...

    SWG Chlorine Generation too low

    I wasn't able to run the ONCL test on Saturday, but I did run one last night. FC 9.5 at 10:30pm and FC 9.5 at 7:30am. Which brings me back to my concern that this SWG is under performing by about a factor of 2. Is there anything else I can check before I go back to the manufacturer?

    Can you post a full picture of the equipment layout and pad? I'm assuming you know that the valve is off in the first picture above?

    SWG Chlorine Generation too low

    I appreciate everyone's responses. I would be much more likely to accept the variance from rating theory if I was measuring more like 70%-90% of rating. But what I'm seeing here is closer to 45%. I was very careful with the overnight test. I turned the pump on at high speed with the SWG off to...

    SWG Chlorine Generation too low

    My new RJ-45+ isn't generating what it should. I just ran an Overnight Chlorine Gain Test and got less than half what I was expecting. This followed a mini-ONCL of about 4 hours where no chlorine was lost at all. Background: This is my first season with a new RJ-45+ SWG. It's been running fine...

    New Pool Owner, New to Pool Maintenance

    Neither of these testing methods are reliable. Please get yourself a quality test kit. Liquid chlorine should be easy to source. Unfortunately, you will find that this is not true. https://www.troublefreepool.com/wiki/index.php?title=Ozone_Systems You can hope, but I'm afraid you never...

    New above ground pool start up

    You're off to a great start! Add chlorine to match the CYA level that will be in the pool when it's all dissolved. Then check pH and TA. You've got this.

    Can you post a full set of test results? When was the last time you deep cleaned your filter?

    High FC Loss

    I would say that you're letting your FC fall too low for your CYA level. At 110ppm, your minimum is 9ppm and your target is 12-14. FC falls faster at higher levels. I would raise FC higher than you have had it, and then move forward with your drain plan to get CYA down to a more manageable...

    Taylor PH reagent question

    Are you sure the new bottle is R-0004 and not R-0014? Those are both phenol reds, but don't work in the same comparitor block.

    New Pool Owner, New to Pool Maintenance

    This is classic pool $tore merry-go-round stuff. Muriatic acid lowers pH and TA. Alkalinity up (which is over-priced baking soda) raises TA, which drags pH back up.

    Debris clogging the pump

    How are you vacuuming? Most manual vacuums pull through the skimmer and basket. So putting a skimmer sock in there will lessen the load into the pump and filter.

    New Pool Owner, New to Pool Maintenance

    If the pool store test is believable, continuing to use the chlorinator is making your problem worse by continuing to add stabilizer and reducing the effectiveness of the little chlorine you have in the pool. The best thing to do right now while you wait for your test kit is to take the tabs out...

    1st Time New Pool Owner ( Long time hot tub owner ) …GREEEEN 🤮

    This means CYA is over 200.:eek: You should do another diluted test of either 2 or 3 parts tap and 1 part pool water. Multiply the final result by 3 or 4. Looks like you're going to have to drain a lot of water to get things right.

    1st Time New Pool Owner ( Long time hot tub owner ) …GREEEEN 🤮

    Are you sure about this? The picture you posted shows the level really low in the tube. That would indicate really high CYA, not 0. Can you check this again or post a better picture?

    You won't get DE in the pool due to a bad check valve.

    Pressure keep's dropping.

    What does your water look like? What does your latest set of chemistry readings look like? Slowly diminishing pump/filter performance is often due to a nascent algae outbreak.

    Do you get any DE in the pump basket when you shut it off? If so, replace the check valve. Otherwise, leave it alone.

    Will the chemicals mix with pool water

    From what I can tell, when the 3-way valve at the outlet of the heater is aligned to the flow you indicated, then then main flow is only going to pass by the 2nd injector closest to the returns. No (or minimal) flow will pass the injector closest to the check valve.
