Yep. But it seems that the booster pump supply T off my main return might be underground. I was hoping somebody here might have an idea why that was done or how far down it might be. Or are you saying it’s not a problem to send the super chlorinated water through the booster and Polaris cleaner?

Thanks. I think I added my details, hopefully to the right place. The booster does feed to its own smaller return in the pool that the Polaris 280 plugs into. But the booster pump always has some water flowing through it when the main pump is running (even when the booster itself is off). It...

Problem is that I think the booster pump may be in line after that, underground. I didn't think I could install a SWG in line before the booster pump?

I am exploring the idea of installing a SWG, which seemed like it would be easy until I realized that some digging may be required. I have a nice long stretch of return line where a salt cell could be added, but the problem is that it seems like the T connection for my booster pump seems to have...

Does anyone have any tips for how to calculate the volume of an irregular-shaped pool? I've included a satellite image of it here. Here are rough measurements: 30' length from end-to-end (longest point) 10-13.5' across at the narrowest and widest points Shallow party pool - only about 3-5'...

Sounds like a good plan. I appreciate the advice.

Looks like fill water is about 190 CH

Great, will do. Now back to the original question - the Pool Math app is telling me to aim for 450, or within 350-550. Would you just leave it alone? It’s getting treated with liquid chlorine and muriatic acid as needed, nothing else being added. When/if it needs to be shocked harder I’ll do...

Retested using the Taylor kit this morning. CH is either 330 or 340. The color change on this this seems a little more gradual so that last drop is giving me trouble. Updated results below - I’ll be adding acid shortly.

The 307 CH came from a pool store test. Everything else in the panel I attached was tested by me using a Taylor kit and new reagents I just ordered from TF Kits. When I tested CH myself using the Taylor kit a week earlier, I got 370. But it was my first time doing the test and I wasn't sure if...

Last week I tested my calcium hardness and the result was 307. I could be mistaken, but I think the Pool Math app told me that level was fine when I entered it. Now it’s a week later and I’ve added some other updated results (TA went down by 20), and the app is telling me the calcium hardness is...

Thanks, I am reading up on it. Some potential issues are that my pool water and fill water are about the same temperature, 64 vs 62 degrees. I also don't have a deep end, it's about 3ft deep on both ends and 5ft deep in the middle. I don't think I have a way to measure TDS. Looks like...

He said the CYA was “off the charts”. I think he used a ton of reagent drops and still didn’t get a valid reading, hence his estimate of over 200. It probably does need to be drained totally. However I am nervous about something happening to the pool with the water all removed. I need/want to...

Thanks for your advice. Do you think I actually need to do the no-drain exchange, or am I just being paranoid? Not sure how much risk there is removing 1/2 the water from an old pool.

I’ve owned this pool for the last 8 months and continued with the same pool service the prior owner used for the last 7 years. They use tablets in it and we started having algae at the end of last season. They tested the CYA this week and of course it was off the charts - he estimated probably...

You’re right, after I posted above I realized the only safe thing to do is leave the breaker off or disconnect the wires at the box. I’ll do that in a bit. I’m wondering if I want to do a new traditional fixture with an LED bulb as you suggest or if I might get a full-LED fixture with only 12V...

I got the fixture out and bulb replaced, put back together with a new gasket, turned it on, and within a few seconds the GFCI tripped. I can’t see water in the fixture itself so I’m afraid just moving it around caused a short in the cord, perhaps right where it enters the fixture. The fixture...

Thanks for that - fingers crossed I have enough cord. If not I might be in a pickle considering how old the conduit and wire probably are.

Hello! The latest issue I have discovered with my new old pool is that there is water in the light fixture. I didn't realize this until yesterday and we have used the light for night swims several times in the last few weeks - whoops. I have only been in this house for a month and didn't have...

Hello - my pool is running an old dual Intermatic timer (T1202 MT). The right timer is used to operate the booster pump which in turn runs my Polaris cleaner. It will turn off, but never on automatically. I replaced the set tab things and it still won't turn on automatically so I believe the...

Thanks for that information. Looks like I need to figure out the software version of the Swimpure Plus control panel to see if it is compatible with any of the current SWGs? I see the 40k SWG works with all versions but I'm sure this pool is nowhere near 40k. I am not sure of the exact pool...
