New to TFPC

@HermanTX - I believe the test kit is still in the mail. So those readings are pretty suspect.

@brennerc - Is the above true, test kit hasn't come yet? If so, just keep adding liquid, until we get the full set of tests from the kit.

Your pool looks about like mine did, when I opened. So odds are that the whole process won't take a long time. Brush and clean, you will have to backwash your filter several times since it will be loading up with a lot of things.

Good job on getting the signature and PoolMath up and running!
Correct the kit is still in the mail. I took a sample in to the local pool store and that was the results from Monday night. Using an old test strip, it looked like just the chlorine was off. Adding more chlorine today.

New pool owner trying to understand test strip reading

Haven’t turned the heat pump on yet since the pool was built about a month ago. My wife wants to use it potentially this weekend with decent weather.

If this was your forecast when would be a good day and time to turn it on so that the temp can get up to 80 degrees. Our pool is 22,800 gallons and you can see our type of heat pump in my signature line. Our water temp currently has a around 65 degrees

Thanks

High TDS with normal CYA

What would cause such a high TDS readout while the other variables are normal, or close to normal?
Salt for one. Many liquid chlorine pools are north of 2000 and you guys get no rain dilution so its likely much higher.

But twice in the last couple of days I saw TDS of 0 with all the other #s in range. (Plenty of TDS). The pool store tests just cant be trusted.

The 0 phosphates in your friends test is highly unlikely, and again calls the whole thing into question.

High TDS with normal CYA

I understand that TDS is no longer considered meaningful because tests for CYA and other variables provide more useful information, and I understand that pool store automated test results should be received with skepticism. That said, a neighbor in Phoenix with an 18,000 gallon plaster pool got pool store test results that seem just plain odd. He sanitizes with liquid chlorine. What would cause such a high TDS readout while the other variables are normal, or close to normal?

ChatGPT made a recommendation for a VSP Hayward Aqualogic P4 compatible pump, can I have your opinion on it please

Based on the pictures I sent can you help me clarify if this is an Ecostar or a Tristar?
The sticker with the Model Number and Serial Number have been removed for some reason.
The body says Ecostar, but the 3200DR refers to a Tristar
Again, the 3200DR is the Drive Only.

DR means drive.

New pool owner trying to understand test strip reading

So it has been two years since my original post. I thought adding a few comments might help speed up the lerarning curve or give some other new pool owners more confidence that they will figure out the testing procedure. If I did, anyone could.

It did initially take me a few weeks to get comfortable performing all the tests and some are more interpretive than others. Within a few months I had the testing procedures memorized as to how many drops of each agent and testing is pretty efficient. Now, on a normal basis I test pH and Chlorine every few days, TA once a week, CH, CYA & Salt every ten days/two weeks. If there is severe weather or a significant change to the water level I will test more frequently. Now, I think I understand my pool better, anticipate what it needs and when based on usage, temperature, weather and changes in water level.

I changed some of the testing equiptment which made a difference for me. First off, I threw the pH test block in the trash. The colors faded and my pH was way off, which caused me a lot of headache in trying to balance the pool and all along it was a shoddy test block. That story is here. I now use the Taylor pH Test Block, which is also more granular than the block that comes with the TF test kit (.2 v.s .3 if I remember correctly), helping me better interpret the pH level. You have to use R-0004 in the Taylor block and not R-0014 that comes with the TF kit. I also replaced both the test cylinders as the lines faded on them quite quickly. I bought glass beakers, a 25 ml for 10ml tests and a 50 ml for TA. It gives plenty of room to swirl the contents well. I don't use a Speed Stir, though you could find a dozen threads on TFP and the benefits/debates of using one. I opted not to go there.

The one test method I changed around was CYA. Rather than filling with pool water to the bottom of the label and agent to the top of the label, I just measure out equal parts of each and add them individually to the test bottle. For me that works better than using the label as a guide.

I will say it was pretty easy getting initially established but is a constant learning process. I have so much more to learn just about pool chemistry, not to mention all the other aspects of maintaining a pool, but TFP is a HUGE help!
Might be a stupid question. But what does CH stand for when you said you test that once every two weeks or so. Is that calcium?

Is there a more accurate cya test than the Taylor kit?

Do you have the 50ppm CYA Standard solution?

I have often checked my eyeballs and lighting by using the standard solution. Since it’s known to be 50ppm, you mix it up with the reagent and then fill the tube to the 50ppm mark. Then you go outside and look at the tube. Find the best lighting and distance from your eyeballs that gives no dot at 50ppm. It’s a good way to check yourself and gain confidence.

Make sure you’re following the directions with regard to holding the tube properly and at the proper distance from your eyes as well as not staring intently at the tube forcing your brain to “see” a dot.

It’s not the greatest test but it’s generally close enough for what is needed.
Is there a number for the 50ppm cya standard test? That maybe my issue. I don't have the confidence that I am measuring it right. It seems like there could be a lot of variables that impact the test. I struggled last summer too, but were working on getting the cya down and I knew it was quite high. We did several partial drains last year and ended the season with about 70 and then drained it down about 25% for the winter. This year I think we are within range. I ended up recording 45. I did the test a couple times with the same solution and I mostly came up with 40 or 50 but did get 60 once. It was cloudy out with the sun peaking through at different brightnesses.

** The Hayward EcoStar brand name and model number SP3400VSP was discontinued in 2017 and 2018. This pump has been rebranded as the Tristar 2.7 HP.

What Is The Difference Between The EcoStar And TriStar 2.7 HP?

The EcoStar and the Tristar VS 2.7 are the same pump.

https://www.swimmingpoolsteve.com/pages/sp3206vsp.html

The bearing are probably bad on that motor.

In my opinion, I would pass on this pump.

First time pool opening and a lot of conflicting information

Be careful with muriatic acid, you have a plaster pool. Don't add large quantities at a time - divide the calculated demand by 2, wait at least an hour after adding and test. Proceed according to the result.
I'm not sure what you are concerned about. I provided guidance in post #10 on how to do acid additions to lower pH. Lowering by .4, waiting 30 minutes, testing, lowering again if necessary.

Even if they say it is, it is highly unlikely that they will actually do that.
True, at my price point I’m definitely taking the chance because it’s like a fire sale.

Based on the pictures I sent can you help me clarify if this is an Ecostar or a Tristar? The body says Ecostar, but the 3200DR refers to a Tristar, so I’m a little confused on which I’m getting.

pavers broke while filling pool

PT wood under the legs?
It's usually the thickness, not the material. Most of the time people use the 2 inch thick 'pavers' that are really stepping stones and only 1.7 or 1.5 inch actual thickness. 3+ inch pavers are actual 2.5+ inch and won't crack.

*edit, just saw your pics in the introduce yourself thread. You used the thin ones. Thats the problem.

Being level is its own can of worms but not why the stepping stones cracked.

Pump Losing Pressure - Need Additional Ideas

If it was my pool...

I would try to prime while running booster pump. If it makes no difference, cap it off.

Last resort, I would try running a hard line from the pump directly to poolside. It sounds like it would only take about two 10 ft sections of pipe and a few fittings to make it work. This would rule out or confirm a leak between the skimmer and pump.

If my ideas get vetoed by the experts, no hard feelings.
Exact same thing was happening to me, that's what i did...Hard line from after filter, but before return to pool...flow was great and it caught prime. Now leak detector dude did say and show me how my return line was corroded from choline where it turned from a hard line to a flex pipe, after it caught prime i did return to main return line and things seem back to normal...day 2..now i'm still gonna give it few more days before i glue everything back.
