Hey all, Thanks in advance for any input on this - should the Hayward TCELL 940 Be listed as T-9 or T-15 in the AquaRite 900 menu system?

Guys thank you very much. I switched from chlorine to SWG this year and I was stuck on the old way of using the Pool Math app. My wife tells me I’m an idiot and like in many cases, she’s right. This forum is such a great resource for pool owners, I learned about it from a friend who owns a pool...

Thank you very much, this was the aha moment I guess I was searching for. I didn’t realize that SWG was a sanitizer option in Pool Math and that picture cleared it up. But I have a follow up - what is the value represented under “24 hour SWG Output”. You used a 2 in your example but I’m not sure...

Hey thanks for these responses. I remain confused as I’m working thru this. I’m pretty familiar with Pool Math and have used it the last several years before this year’s switch to the SWG. I’m not sure how I can use it to calculate % and run time. Mknauss you said to set the SWCG to generate 3...

Hi everyone, I had started a similar thread about test kits but I guess I need some general help with my new switch to SWG from chlorine so I’m starting this thread. The new SWG pool is a vinyl liner with about 20,000 gallons, DE filter and Hayward TCell 940 w/ Hayward AquaRite 900. New water...

Ok thanks I mostly follow this but I have two follow ups. What product should I get to add cya? I can follow the SWG instruction manual recommendations to add the suggested amount of salt, but how do I know when it’s actually up and running properly?

Hi so my new SWG pool (vinyl liner with about 22,000 gallons, DE filter and Hayward TCell 940 w/ Hayward AquaRite 900) pool pump, filter and chlorinater have been up and running since Friday. Since Friday I’ve added 8 bags of salt (not all at once), as the AquaRite manual said I would probably...

Thanks for the info, I just ordered that add on kit. What levels do I continue to test - pH and FC or I ignore the FC and focus on the salt?

Hey all - I was a new pool owner 4 summers ago and we’re just finishing a renovation and a conversion from chlorine to a salt water system. This website was a tremendous help in bringing me up to speed with the old pool, and I expect it will continue to be a great resource with the new pool...

I’ve come across a condundrum while installing a Hayward pool light model #SP0670U. The light came with 10 screws to install the light face plate, gasket and rear bracket on each side of the pool wall. The supplied screws are listed as #13 1 1/4 inches. I’ve attached a picture from the manual...

Thanks for reply. I think I figured it out and it’s a Hayward threaded wall plate.

Hi I’m trying to fix a leak which I posted about in the starting/closing thread. I’m trying to replace a wall plate/return fitting but I can’t seem to find exactly what I’m looking for neither online nor at hardware stores. Where I am in Mass the pool supply stores are still closed down. I’ve...

FYI - Second photo came thru upside down.

So I inherited an old pool which I am opening for my third season. Just took the cover off and the water looked great, however, the level was way down and it lost about 9,000 gallons over the winter. I’ll attach some photos but I think the culprit is an old return line that was capped sometime...

Within the last 2 weeks I stopped using pucks and just have been adding liquid chlorine daily. I’ve felt like I’ve been battling low pH all year and so I finally heeded advice here to stop using the pucks. My pool looked slightly cloudy last night so I did an Overnight Loss Test and lost 2.0...

Not the Taylor-100 but the other Taylor kit recommended on this site.

Hi I’m a second season pool owner (not salt water). This year I have been consistently measuring 7.0 to 7.2 pH and adjusting to try to get it closer to 7.4-7.6 range. My CYA is consistently 80 using liquid chlorine to shock and 99/1% pucks. I kept my chlorine according to the chart on this site...

Thanks. It’s easy for me to feel dumb and but I thought the 131 oz was referring to a liquid product. I should’ve done some division. I’m ready to move away from the pucks I think but what’s the alternative, adding some liquid chlorine every day?

Hi I’m a second season pool owner running into low TA. I’ve been fighting lower pH this year and just looked at the TA this morning to find it at 50. This morning my FC is 7, CYA 80 and pH 7.2. Like I mentioned I’ve been encountering low pH all season. I know the CYA is high I use the pucks and...

Thanks for input so far. My CYA was 55-60 range for most of season and I ran my FC about 6-8. I chlorinate with pucks in the skimmer basket and add 12.5% liquid when a shock needed after heavy weekend usage. The pool is very old with a single skimmer and single return line that isn’t the...

I’m prepping to close my pool this weekend here in Massachusetts. We’ve had alot of rain and we haven’t used the pool in a few weeks. I tested the water as part of my prep for closing and things seem off: FC - 17.5 pH - 7.0 CYA - 90 Alkalinity - 60 The high FC caught my attention and I’m not...

Thanks yes. Just found the instructions for one brand that said max of 11oz per 10,000 gallons. So that would put me roughly at 1 quart. Thanks again.

Coming to the end of my first season as a pool owner. The advice at TFP helped to make it a fun season. I’m going to close my pool and I’m not sure how much Polyquat 60 to use for my 28,000 gallon in ground pool. I’d appreciate any recommendations? I’ve read the posts that say to follow the...
