An existing 10kohm resistor on the board you mean? And by checking if it is also reading 10k like the sensor? Sorry, I'm a bit novice with a multimeter.

Can the board be tested as well with a multimeter?

Yeah, that would be the green board in the image.

Like the green board in this image? Or the display screen? or both? :cry:

Sensor disconnected, read at connector plug, was reading 10k-10.3k ohms, air temperature was about 65 degrees I'd say? Sunny area.

Even if it has the correct ohm reading? I'll grab some contact cleaner to rule it out maybe...but everything on the panel was actually pretty clean/crisp looking. I do have the part, so I could always swap it and see. Just trying to feel out if they are any other likely issues before doing...

Hey all, My swimming pool has an Aquacal SQ145AHDSBPB Heater. The control panel is reading the pool temperature as 102-104 degrees (it's actual temp is about 70 degrees). I have not tried to turn the heater 'on' at all. I did read the common cause it the temperature sensor so I ordered the...

Okay, so I've closed my pool and it went pretty well. I didn't love how my 'few year old' gizzmos fit, not sure if the threads are out of whack or what...so I ordered new ones and I might just blow the skimmer lines again on a warm day and use the new gizzmos instead. Also, curious....besides...

Yeah, for sure. I'll have a helper on hand so that will make it more manageable. I think I'll grab gizzmos with the spout on top in the future....that'll make it simple. Just wasn't sure if it was a major nono to leave water in the basket but with the gizzmo and some pool noodle, should be...

Great, much appreciated. That's a good point as well, I do want the water level up for the pool cover. I'll 'battle' to get the gizmo in, then add some pool noodle as well. Now I'll see if my pancake air compressor will get the job done, or if I need to hunt down a cyclone blower. Thanks!

Hey y'all, So I'm closing my pool for the first time, but I know for a fact the pool company who had done it the previous few years never dropped the pool water level at closing time. If I blow the skimmer lines won't it be impossible to keep the water out if the water level is the normal...

Hahaha, true! I'll research a bit before making a final decision. Thank you for the help!

Thanks for the reply on the adhesive, concerning using it....I'm not opposed to mortaring the polymer wall area (as well as the concrete collar portion), I just was under the impression the mortar wouldn't adhere well to the polymer wall edge? Using just mortar instead of adhesive/mortar sounds...

Hey all, Can anyone recommend a good adhesive choice for bonding natural stones to a polymer pool wall? I'll use mortar along the concrete collar, but I think adhesive would be better where the polymer wall is. Thanks!

pH held @ 7.2 after 4lbs of Cyanuric Acid. CYA must of been really low as it is only at about 30. I'm going to add another 4 lbs which should bring it up to 50-60. FC is slowly trickling down to 5 FC, it's currently at 7.5 FC. Tweaking the SWG/pump schedule to get it to hold at 5FC. Should...

Okay, just finished a SLAM...and now I've installed my new SWG cell and cord. I'll monitor FC closely for a few days to see if it's working...but warning lights are off. With the new cell, I'm at 18Volts and 6.5amps at first check after install.

Nice! I'll get it down to 5ppm FC for normal day to day operation, then take a full retest of all levels. Thanks again for the help!

Was at 11ppm FC when I tested it at 9pm. I wasn't going to have time to add chlorine and retest, so I left it at that. A 7am water sample tested at 10ppm FC. CYA is currently near 30.

Okay, so results this morning were: .5 or less CCs, 1ppm FC loss overnight, water is clear. I think I'm good to go?

Okay, meant to post earlier...water looks super clear, and my CCs were under .5 this morning. I'll do an OCLT tonight for the final hurdle. Thanks!

Yeah, that's exactly what I did...filled to 25ml. My fault it says "using the 25ml" and I just filled to 25ml! I did retest with 10ml, and salt was at 3100. Thanks!

Okay, so I'm scrubbing my brain from my pool company's shoddy advice and I'm now curious how to best utilize my pump. They had me running it 23 hours a day, 3 equal time lengths with speeds of 1700, 2300, 2700. I'm currently slamming and running @ 2000 24/7 until the slam is finished. What...

Great, on it!

I'm @ 7.4 pH, with the CYA also lowering it a bit, is that sufficient?

So with my CYA 'under 20' I added a 2lb cyanuric acid sock to the skimmer...which should raise it by 15. At this point, maintain 5ppm FC until my CYA is officially up, correct?

Okay, got it, thanks again!

Ahhh, thanks...was just asking about my CYA, I'll get that to 30, then get my FC to 12...and go from there with FC testing. Thanks!

Okay, so here are my current pool levels this morning (FC tested at 4ppm last night, after sundown) FC: 2.5-3.0ppm (tiniest bit of color left after 5 drops) TA: 65 CH: 275 CYA: under 20 ph: 7.4 CL: 3+ Salt: This test didn't work for me, liquid was getting cloudy, but no color change to...
