I have been battling scaling in my SWG. I've been careful about keeping my CSI slightly negative, but still lots of calcium buildup. Granted my CH is getting really high and I'll need to drain soon, I still just don't understand why I'm getting so much scaling even though I believe my pool...

It seems like there must be some device out there that could remove calcium from my water in my pool without costing an arm and leg. I just really don't want to have to drain my pool since every other aspect of my water is fine, but my calcium hardness is above 700 now and the scaling on my swg...

I have a ~13k gallon play pool that I need resurfaced, and old cool decking that needs to be replaced. This quote is in line with what I was expecting, but I wanted to see if anyone had any thoughts or advice to share. Also - any opinions on StoneScapes brand pebbles vs pebbletec?

After dealing with chronic high pH and SWCG cell scaling issues, I've taken the advice here and lowered my TA from 100 to 50 over the past month using aeration and regularly adding muratic acid to bring the pH back down. One observation, is that it is surprising to me how long this process...

Hey all - I have been running a Circupool core35 SWG for ~1.5 years now. Full disclosure, I didn't do any maintenance/checking beyond looking at the lights for the first year. This past May, I took it out and saw there was some calcium (??) buildup on the cell, but much less than you see in...

I'm considering fully automating my pool to include pH management - due to high TA fill water where I live, my pH will always creep up to ~8.2 within a week (from 7.6) unless I add small amounts of acid each day or two. I realize there off-the-shelf systems for this, as well as CO2 injection...

I have dark mode enabled on my phone (so that the menus, settings, theme, etc are dark), but most apps I override this to just be light mode. Pool math doesn't seem to have any option to override this and just uses whatever the system default is. I find it really hard to see what's on the...

My CH is 275, which is on the low end of the recommended range for a plaster pool. I have softened fill water, so it's not going to rise on it's own, it's actually fallen slightly since the beginning of this season. Two questions: Is this CH level range ok in the long run? How low is 'too...

I converted our pool to SWG at the beginning of this season and, among other benefits, was looking forward to the "feel" of salt water that everyone seems to notice. I do like the SWG but the water feels no different to me than before, and if anything I have noticed that my skin consistently...

... and I'm happy to report that my pool is almost exactly as I left it ☺ save for high pH (8.2) which is expected since nobody was adding acid for a week. I guess I can't say I really expected anything different, but it's so nice to be able to go away without worrying about coming home to a...

Hi - I have an old pool light original to the pool that burned out years ago now. I recently had the pool drained and thought I might go ahead and replace the bulb, but the top screw holding it in place was NOT going to budge. It was unscrewed maybe 1/4th of an inch already for some reason, so...

Thanks to all of you who helped me with guidance over the past few months as I learned the way of the TFP to balance my pool chemistry, and then installed a SWCG in my pool. Since the CORE-35 has a clear housing, you can see the hydrogen bubbles generated as it creates chlorine. For some reason...

My pool pH likes to stabilize at 8.0. I can add a gallon of acid in the water and within a few days it's back up to 8.0, but still distinctly below 8.2. It will stay stable at 8.0 seemingly indefinitely. Is this acceptable, or do I need to shoot for keeping it a bit lower at 7.6-7.8? I just...

Hi - I am installing a CORE-35 SWCG this weekend. My current plumbing only really has one straight run on the return side where it makes sense to install this. I've outlined it in red in the attached picture. Just in case anyone is curious, the valve on top allows me to switch the return from...

Good day TFP people! Our pool deck has a Cool Deck coating installed back when the pool was built in 2001 (est. as I was not the owner of the house back then). 20 years later now, it is deteriorating in several places and is on my shortlist of things to replace in the next year or two. I was...

I just got the tf100 testing kit and tested my pool water. My results are below as you can see basically nothing is where it should be, but notably cya and calcium hardness are very high. Separately, but related, I purchased a core 35 saltwater chlorine generator and plans to install it once it...

Hello! I have a 10,000gal pool in the Phoenix area that I am planning on installing a salt water chlorine generator in. I'm currently debating between the CircuPool CORE-35 Salt Chlorine Generator and the CircuPool RJ-30 PLUS Salt Chlorine Generator. My main considerations are ease of...
