I have an AquaSport 52 with a good quality, thick vinyl liner. The pool is 4 years old and this year I noticed that on one side of my pool the very top of the bead on the vinyl liner is discolored/yellowed. To me it looks like sun damage. This is only happening on one side on about 15 feet of...

"Best advice is to get one of the two test kits TFP recommends and use the “pool math” app on your phone to figure out where you’re at." So much this. I've been using TFTestKits.net chems and the Pool Math app for 3 years running and both are BRILLIANT. My pool isn't just clean, it actually...

NICE!

Thanks for the fast reply! Good info. I probably won't worry too much about it then. Yeah, 54F is chilly for me too but... I usually do a Polar Plunge with my teen boys the day we close the pool 🥶 and of course they make jokes about shriveled raisins LOL. Being in-ground the pool doesn't freeze...

Background I live in Utah where we get cold snowy winters. This is the third year closing my pool so I'm becoming a pro at it. I'm meticulous about checking and balancing chems daily & weekly when the pool is in operation. In preparation for closing, 7 days ago I shocked using 7.5% bleach to...

That explained it perfectly and is exactly what I needed to know. THANK YOU!! For future reference for anyone else with this question, the TFP page with the CYA vs Chlorine chart is here: https://www.troublefreepool.com/blog/2019/01/18/chlorine-cya-chart/

This is my second year using the TFP app to track and balance my pool's chem levels. Last year I used pucks but due to escalating CYA issues I switched this year to liquid bleach. It has been working great but I want to make sure I'm not adding too much chlorine. Current Levels: FC: 5 pH...

@JamesW & @RaleighDawg: Thanks for the replies! I started suspecting it might be reflective solar damage when the duct tape I put on the holes also melted. Yikes. I then stepped out to look at it at various times during the day and, viola, you can see the reflection from our big South window and...

One side of my 18' pool cover appears to be "melting". This is not happening on the entire cover but only on one side, and only where it's _not_ touching water. Anywhere it's touching water is fine. The cover is GLI's top-of-the line cover and it's only been on the pool for ~2 months. When I...

Thanks for the reply. I won't worry too much then. Yes, reasonable TA and perfect pH is what I'm trying to accomplish as we go into winter and the pool is covered for several months. I also had a hunch the borates were part of the equation but I'm new to this so I was unsure. Thanks for...

Context I built the pool in the Spring this year. Stats are in my sig. Our tap water has naturally high TA and low-ish pH. For most of the summer we used Chlorox pucks in a floater for chlorination. Because of the pucks my CYA was getting out of control and pH kept dropping. I stopped using the...

Yeah, I see the problem. Thanks for the info. I've owned an Intex pool for several years and the pucks worked fine because it was small and we did a drain + refill every year. This year we installed a larger, more permanent AquaSport partially in-ground so now I'm getting educated on real pool...

Thanks for taking time to reply. I really appreciate the info!

We had an Intex pool for years to the tabs are all I'm familiar with. Do you just use chlorine bleach? If not, what do you use and where to you get it from? How often do you typically add the liquid stuff? FWIW, I've been keeping a close eye on the CYA and it's rising very slowly. I need to...

Yes, using Chlorox trichlor 3" tablets for convenience. My borate levels started to reach the 60ppm range so I stopped adding borax and tried aerating. It worked. I aerated for 7 hours and was able to get the pH from 7.1 up to 7.3. I'm aerating for another 8 hours today. Details are here: My...

Yes, Venturi Effect pulls air into the return stream. I first tested by just holding a section of pipe over the return stream and it made a jet of bubbles. I'm still surprised it was so simple and it works in raising pH.

I've received a lot of useful help from this forum and want to give back a bit. My pool pH keeps dropping weekly and I need to raise pH without touching my already high TA so as a quick fix I've been adding Borax. I reached the 60ppm threshold and needed to start aerating. I looked at the "SPA...

Summary: Out of the tap my water has low-ish pH (7.2) and high TA (120). The TA has been stable but the pH keeps dropping. over the past 6 weeks I keep adding borax to raise pH but not affect TA and it works, but then after a week or two the pH drops again. I've scoured the TFP forums and Google...

This sprint I built an Aquasport 52 18' partial in-ground pool and we've been LOVING it this summer. I just cleaned the filter for the first time and followed the instructions on Pool School and did a TSP deep cleaning and that worked fantastic. As I went through the cleaning process for the...

Thankfully, Yes. He looked at the pump cord and specs before getting the parts. It's all sitting in my utility room waiting to be finished.

Thanks for the replies. As an amusing follow-up, I prepped the pad for the pump, finished filling the pool and installing skimmer and return, and attached the pump. I then started a SLAM and brushed the pool. I pulled the cord out to the pump and at 12:15am FINALLY went to plug it in and... the...

I just built the pool (AquaSport 52 18' Round). The pavers on the pool deck are still going in so we filled the pool up to the skimmer then sealed it with heavy guage plastic sheeting to keep the dust out from landscaping + pavers. Nobody got in the pool and it was clean tap water so I thought...

I'm posting a follow up for anyone who may have this question in the future. We tried a couple different approaches and found one that worked really well. Instead of having cove pieces meet at the corners of the pool, we centered each full cove piece at each corner then cut a small 1" triangular...

Our AquaSport 52 18' Round pool is now constructed and we are ready to install the foam cove then lay and compact the sand base. I purchased the right amount of Gladon foam cove from Amazon, as recommended by the place where we purchased the pool. Two questions: 1) I was planning on installing...
