Thanks Catanzaro. I have only 1 skimmer and no main drain. I have been using the vacuum every other day for over 3 years now. This problem has just suddenly occurred, which tells me it has nothing to do with how I'm filling the vacuum hose. The guy at the local pool store also showed me an...

Thank you, I will, as soon as I can.

Thank you for your support. The new hose didn't solve the problem. I believe there may be an issue with the hard plumbing, as we're having drought here in TX and ground shifting. I've exhausted every other possibility. Thanks again.

I have examined the hose for any tiny hole and see none, and if it were a hole in the vacuum attachment point (i.e. the under-water hole to the skimmer), wouldn't it cause loss of vacuum all the time and not just when the vacuum hose was attached? I'm inclined to just buy a new hose, as I can't...

Yes.

I'm having trouble when trying to vacuum the pool. I'm doing it the same way I've been doing it for the past few years, but suddenly the pump started losing its prime once the vacuum was used. I have removed and lubed the gaskets, but as long as the vacuum isn't attached, the pump runs fine. I...

I'm testing with the recommended Taylor kit. You may be right that I'm not keeping the chlorine level consistently high enough. The pool is clean except for the yellow stuff that brushes up. Not a leaf or bit of other debris is in it. And the fact that the filter water is green, tells me it's...

Pool season greetings, I have been "slamming" the water for almost a month now to get rid of cloudiness, brushing bottom and sides daily and cleaning (green with algae) cartridge filter every few days. Using Sodium Hypochlorite 6%, holding chlorine level between 10 and 15. We've had lots of...

"Failed Chemistry" asked a question that's on my mind about shelf life of MA. My gallon bottle of Transchem muriatic acid says to dispose of it after 6 months. Mine is about a year old. I didn't think it expired, but now that I've read the label... I have added 6 oz to my 6000 gal pool twice in...

Thank you everyone for your helpful input!

That's a good point, Nathan. I have replaced water, so I must assume that my last CYA test was prior to the addition. I have also made the error of adding too much water only having to drain some off (a serious error here in drought-ridden TX). My testing chemical for CYA is fairly new, so I'm...

I'm sure this isn't a "new topic", but I can't locate an existing thread. Just got back from out of town and the pool water is turbid. pH is good, but CYA is not registering at all; no cloudiness in the test vial. I need to SLAM the pool ASAP, so can someone tell me the best CYA product for the...

Pool surface is vinyl. No, I don't know how CH got so high. Originally, I was using the chlorine tabs, but the CYA was so high that pool store sold me Calcium caplets, same product as "turbo shock", which supplier reassured me had no CYA in it. But that's only been for the past 2 months or so...

The pool is again draining...evidently I needed to tend to the CH before correcting pH and TA. The pool calculator recommended a 56% drain and refill with 0 CH refill. Hope municipal water isn't high. On reducing the TA, the part I missed was the repetition of the process. Guess that could take...

Since Thursday and the incremental addition of muriatic acid, the pH has come down from 8 to 7.2, but, alas, the TA has only come down from 150 to 125. Now that pH is so low, how do I bring down the TA? And, the CH is at 450! How do I bring that down?? Tech support from Taylor Kits said there...

If the test is using the 10 ml of water, the smaller sample, the number of drops to the turning of color is multiplied by 25, not 10, making the TA 100.

Your explanation is a little unclear; It took 4 drops to go from green to clear, but then another 76 drops to turn red, equalling the "80" drops you earlier stated?? The alkalinity test uses the 3 different reagents, 0007, 0008, 0009. I have a relatively small pool with vinyl liner and have also...

Thanks for the idea, but after looking online at the process of powder coating, it looks like a complicated process for which special application tools are needed, etc. Too involved. If I knew someone in the business...but I don't.

Don't know which test kit you have, but on the Taylor K-2006, it gives instructions on how to do the TA test using less water and reagent if you expect a high result. Could it be your 0009 is old/bad?

I have metal handrails, painted white, that attach (underwater) to the steps in the pool that are peeling due to the prior imbalance in the water. I haven't yet located a source for paint suitable for metal submerged in swimming pools. Does anyone have any knowledge of such paint, or any...

Nancy, Have you considered contacting Endless Pool to see if they're familiar with the issue?

I redid the CYA test, and I think it's closer to 50 than 70. The black dot seems to disappear and then slightly reappear...The FC is up to 16.5, and the CC is at .5. I'll try out the pool calculator.

I had read somewhere on the forum just how much (ppm) a gallon of bleach would raise the chlorine level in a 10,000 gal. pool, but I didn't record it and couldn't find it again. I wondered if another 3 wouldn't be too much, but testing after the first 3 took only 1 drop to turn the pink water...

Well...I already added 3 gallons bleach this morning, cleaned filter and vacuumed, checked FC 2 hours later and it was negligible. Just added another 3 gallons as well as drained some water as the rain last night overfilled. BTW, I stopped by the pool store to get the 12%, but they don't carry...

I've done 2 partial drains, and last night's CYA test looked to be about 70. CH is 500. At least. TA 130 pH 7.6

Thanks to all for the good and needed advice! We had rain last night. My pool is green this morning. I did the overnight test as recommended, removing the calcium hypochlorite caplet from the skimmer 30 minutes before the test last night. The water, obviously, has NO FC. I'm ready to pour in the...

I forgot about "shock" being a source. I added 1/2 bag a couple of days ago and likely need to do it again. Or, should I just start using bleach and skip the shock. I'm happy to use the liquid, but that leaves me without a solution for time away.

The water did go pink immediately, but I could still see particles floating around, and once I set the tube down, the water returned to clear. Is the one and only way of lowering CYA to drain the water? I've drained it twice already, and water is a precious commodity in TX. Where is it coming...

Thank you for your replies. I'll get a speed stir and read more on the extended test tips. My powder didn't dissolve immediately. I travel for about a week out of every month. Any ideas on how to keep the pool chlorinated while away? SWG is out of the question. Could I use the daily bleach...

Greetings, My test kit arrived. I've drained half the water and refilled which successfully lowered the CYA from 100 to 49, but raised the TA to 130, according to the pool store test yesterday morning. Their recommendation was to add acid, which I had just drained half the water to reduce. But...
