Thanks. There are multiple spots, but I don't really have much of a choice. I'm in WA state. The next few days will be sunny and I am going to be keeping the plaster wet while I am cleaning the rust spots, etc. Then we have about a week of rain. I'm hoping to get everything cleaned up over...

Do you think I could buy a year or two by doing spot repairs? I couldn't really afford a replaster right now even if I could find someone to schedule it in time for the season.

You know... I thought that they did (I wasn't really paying attention at the time). But I just looked back at the photos and it looks like they just chipped out spots.

After about 10 years from a replaster, I noticed a number of chips in the plaster. Plus there are some ugly rust stains from putting a 12 foot skeleton in the pool for our haunted house. (It was for a good cause). Anyway, I decided to drain the pool for the first time in 10 years to patch...

Hi all... Thanks for the replies so far...Here are some clarifications (Hopefully you all won't be too horrified). I usually do not winterize the pool. I don't even have a cover for the pool. I just set the timer to run the filter for about an hour overnight and if we hit a cold snap I will...

I have an inground plaster pool. The plaster is about 10 years old and is getting a little rough. I'm not really prepared financially to replaster it so I was considering doing some spot work this spring: Maybe some spot acid washing of some stubborn stains. There are a few chips in the...

I'm a little intimidated to tie into the existing waste line, where the diverter is because of the lack of space. Also, the existing waste line just goes out to another place in the yard and I end up flooding two neighbors' yards (in addition to my own) when I divert to it. If I was going to...

Long story short: I have a canister filter that replaced a sand filter. The plumbing is set up with a diverter valve that diverts the water to waste instead of returning to the pool. The problem is that it diverts the water to waste after it goes through the filter. So if I vacuum to waste I...

I'm starting to get that impression. The FAS/DPD test behaved oddly. I'm using a magnetic stirrer, and the red would clear after about 4 drops. Then after about 5 seconds, the red would come back. I would clear it with more drops, and the red would come back again, until I got up to 15. The...

Here's a picture of the foam, and in the background, the sparkling clear pool, which 2 months ago was a swamp. I can maintain the pool blindfolded using TFP method. A few glugs of bleach every day or two. Maybe a glug of acid once a week. Couple handfuls of baking soda a month. But, the hot...

I have some more information, and a bit of an "ah ha" moment. Here are some numbers I ran: CH: 240 (High, but not obscene) TA: 60 (A little on the low side than I am used to in the pool, but should be OK) pH: Low (Can only test with test strips right now. CYA: 0 (Expected) FC: 15...

Hi, I've been using TFP process on my 15,000 gallon pool for years now without a problem. About a week ago, I got a brand new hot tub (Tropical Seas Spa Rio 751L). It came with that Frog system, and a UV/Ozone sanitation system. I'm not a big fan of them. But, I figured since the Frog...

I'd put the Borax in now to target your 7.2 and see what your numbers look like in the morning. Your pH was likely this low all winter, so I don't imagine it would have jumped up that much over night... especially given your low TA values. And, I probably wouldn't suggest taking any action on...

The pool calculator is pretty accurate. If you put in the recommended amounts, and it didn't hit your 7.2 target, I'd wait at least an hour before adding more. You don't want to start playing whack a mole with your pH.

I'd suggest to stop adding stuff until you get your pH in line. You don't get good test results on pH when you are at shock. Where are you getting your test results from? I have never owned a pH test that could test up to 9. Make sure that your test results are good, and then go to the pool...

You're gonna need to keep an eye on your pH definately. With your high TA and... well... not low CH, combine that with a high pH and you're in the scaling range. I'd be shooting for about 7.2 for pH... though you should be OK up to about 7.5... 7.6. That will drive down your TA eventually...

It helps buffer your pH. (Though, honestly, I'm not sure of soda ash helps with that). It adds borates to your pool which gives the water a softer feel. It helps control algae. Can purchase it at the grocery store, and is usually right next to bleach. I get to take it away from my son, who...

I actually like using Borax better to raise pH. Check the pool calculator yourself, but I am seeing that 115 oz of borax will raise your pH from 6.8 to 7.2.

Do you mean your water is "sparkling"? That's a good thing :) I can't see anything else in the picture.

You didn't ask about pH... But, how did you get the 6.8 reading? And did you know why it is low? I get concerned when I see a 6.8 reading, because, that's how low many tests go, which often means you don't know how low it really is. Also, if "6.8" is where your pool naturally finds it's...

If you are starting at a CYA of "21" as tested by the pool store, adding 5 lbs of CYA will take you to 45 (as tested by the pool store). I would hold off on adding CYA until you get a good test. Also test your CH. Yes... your TA is high... but it is only worth targeting if it is contributing...

20 is too high for swimming even if your CYA really is 40.

Not really... for me, ammonia is more of a "boy... this SLAM isn't working... I wonder what's going on" type of problem then a "let's figure it out first" kind of thing. But, since your pool has been sitting wouldn't hurt to run to the pet store and pick up a test kit.... assuming that you...

Sounds like a good plan. You can start with your CYA in now. Add it to a sock, and hang the sock by your return jets. I'd run the filter 24/7, and get all the physical stuff out that you can. Whatever you can get out with a net is best. Be aware that if you are needing to backwash, or...

That looks right. Here are some recommended chemicals: Pool School - Recommended Pool Chemicals I'd get a little extra. 250 is the lower end of the scale for plaster. But, getting rid of CH means draining and refilling, so I'd rather not overshoot. After you get things better situation, we...

Re: Here are my readings.Help!! I want to use the darn thing before summer is over, Everything looks good. No need to worry about your TA level. Means you will have high acid demand, and when you bring down your pH, it will gradually knock down your TA, eventually finding equilibrium...

Absolutely not. It's just that you are going to want to get your pH down. And: 1) Chlorine is more effective with lower pH 2) You shouldn't really be playing with your pH during a SLAM. But, with your low TA and CH, if you lower your pH, you will be out of the safe zone for the plaster...
