Feedback on AZ pool design

3' is extremely shallow. I'd recommend 4' for the shallow end.


Get the IntelliFlo3


Get a robot.


I wouldn't recommend an IFCS. Adds a lot of cost, complexity, and potential failure points to your pool. A robot will clean much better at a tiny fraction of the price.


Make sure they all point away from the house/main seating area.

Definitely get a SWCG. Are you getting a heater or chiller? How many returns?


Thanks for the feedback! Good call on the in-floor cleaning; I’ll ask to have that removed. I don’t think I’ll need a heater (pool will get full sun and no deep end) but a chiller might be nice for AZ. I’m not sure what you mean by returns?

Never thought I'd ever have to worry but I need outdoor security cameras!

Yes sentry guns! You ever see the motion detected water hose that sprays the deer. Wonder if they ever just get used to it. My wife yells at the deer through the ring cameras all the time. In NJ they are everywhere and basically give you the big middle finger unless you literally get right on top of them. We need wolves back in the ecosystem and nature would balance herself again. They effectively have no predators in our area to speak of as the bears are few and far between unless you are really in the sticks.

Perhaps security cameras with facial recognition that shoot tear gas pellets at unfamiliar intruders …

When determining pool volume with a chemical test which test is best?

Ironically that's worse. With a blood sugar of 100, the meters are +/- 20, which is the high and low #s (120 or 80) usually needing a correction. You could be dead on perfect and be considering a correction on either end.

It's the diabetes version of testing at Leslie's. :ROFLMAO:
Obviously I am not a doctor, but I was hoping that glucose test was more precise - oh well - bad analogy.

Water leak at pump

Hello everyone,

I found out I have a small leak on the tube going upward from my pomp to my filter. I try putting it tighter but it didn't help. Looking at the installation, it seems there's some kind of silicone that was applied at the installation. How do I fix this?

Thank you!
The silicone will pull off easily. You can't seal a pressure leak from the outside with silicone. Remove the union, with Teflon tape wrap about 5 or 6 tight wraps, put a bit of silicone sealant over that and reinstall the union. In the picture the part is already threaded in too far. There should always be about 3-5 threads showing in a properly tightened fitting like that. If it has to be threaded in all the way to stop the leak, get a new union, the existing one is ruined.

University Lead Pool Operator

Hello everyone!
I am the lead pool operator (CPO in charge) at the University of South Carolina in Campus Recreation. I am in charge of 3 pools (Outdoor Pool-115K gal, Indoor Pool-140K gal, and Spa-1,500 gal.). I have seen this forum online looking for advice to deal with algae, and I wanted to go ahead and join so I can make all 3 of my pools the best they can be! Mad respect to all you pool owners and CPOs out there! You can see me on the algae forum soon because my outdoor pool is currently in the throws of battle!

Can CYA disappear with decent FC level?

Hello, everyone!
I'm back with questions. :D

I am suddenly reading zero CYA in school pool.
Date: FC: CYA:
April 29. 7.5. 40
April 30 7.5. 30
+1.5 gal bleach
April 30 13.0
April 30. 13.5
May 1. 13.5
May 1. 11.5. 35
+0.5 gal bleach
May 3. 13.5. 40
May 6. 6.5 40
May 8. 7.5. 0 😱

On May 7, I reloaded CYA reagent. First, I tested dad's pool and got no CYA reading, which was reasonable for the pool that became complete mess after flooding (his area got 10" of rain). So I didn't think anything was off.

But then I also get the same result at school pool, which looked nice and clean through all this time.

Do you all think that it is a bad reagent or that I suddenly got a problem in school pool that causes CYA to truly dissappear? If latter, what is it and how do I fix it?

Thank you!

P. S. I'm currently in third attempt at SLAMing the pool. Previous attempts were interrupted by torrential rains.
P. P. S. Dad's "complete pool mess" included solid green walls, liner that floated up and off the retainer ledge, water receding below skimmers, etc. We're still working on it.

Water leak at pump

Is the leak coming from the connection into the top of the pump? That large diameter white piece looks like a union. that union has a seal in it. Could that be leaking “down” and it appears the leak is from the black connection? If it is the Union, then just undo it, lube the seal in it and retighten.

If it is the connection to the pump, then I would stop the pump, undo the Union and then unscrew the piece going into the pump. Adding more silicone won’t help. It is best to unscrew it, check the threads and also there may be an oring seal, lube it and reinstall it.

PoolMath not making sense to me

I also know that raising and lowering chlorine has an opposite effect on pH reading.
Lifted from the Ph Wiki :

What is the Effect of Adding Liquid Chlorine on pH?[edit]​

It is a myth that liquid chlorine will raise pH. The myth is based on a misunderstanding of chlorine chemistry.

Adding liquid chlorine to water can cause a temporary increase in pH which is usually offset by the chlorine reacting with organics and biological matter which are acidic (creates a proton) reactions. Thus, on balance, the net chlorine reactions are pH neutral.[7]

Most retail and commercial liquid chlorine products contain a small excess of lye from the manufacturing process but this amount of OH- is minimal and does not change the pH with normal levels of liquid chlorine use.

If one were to add significant amounts of liquid chlorine (for example, raising the pool water chlorine concentration to SLAM FC levels), then the pH rise would need to be offset by an initial lower of the pH with acid. This is why TFP requires a pool owner to adjust their pH down to 7.2 prior to starting the SLAM Process.

Adding liquid chlorine DOES increase the pH at first, however as it's used up the acid that's created lowers it back down to where it was before......thus equaling each other out making it pH neutral.



The TFP Wiki is towards the bottom of any forum page and also in the left screen sidebar. Browse through whenever you have a thought/question. Peruse anything relevant to you in your free time. :)

Old neglected pool, what to do??

Do you have any idea what dollar amounts I may be looking at? Thank you so much for your advice.
I do not. There are many variables. Where do you live? Rural? Good luck finding pool companies. City? One with lots of pools = lots of pool company options.

You have "Layers" of issues to inspect and confirm
  1. Is the concrete shell sound, if yes, then you might get away with a new plaster if needed. If not, you may have significant work to save the shell.
  2. Is the plaster in good condition and holding water? If yes to #1 and #2, a cleaning will do. If no to #2, then you need to chip out and replaster the pool.
  3. You have coping issues (see picture). It has a gap between the tile and the coping. The coping likely needs to be reset. 1715284743413.png
  4. Next is plumbing, you certainly have one bad skimmer, don't know if you have two and the condition of it. You have no idea the condition of the plumbing to the pad. Looking at the pictures, you have flexible PVC. Not the greatest stuff, might be serviceable...just don't know until you get to it.
  5. Deck. Hard to tell the condition of the entire deck, but you have cracking and shifting that would need to be repaired...without looking at the entire in detail, you may get away with just repairing sections...also depends on the result of repairing the coping issue.
  6. Equipment. It has been covered, which is better than sitting out. You have a simple system with a pump and filter. Filter is likely fine, IF it was winterized properly...if not and water was left in it, may be an issue. Unclear the probability the pump is any good.
You have lots of discovery and evaluation to do on this pool. I don't want to scare you, I want you to be realistic about what it *might* take to get it up and running. It is also my experience that the visible problems are 10-20% of the non-visible problems. Visible problems tend to be cheaper to repair. Non-visible problems tend to be more expensive to repair. It is also my experience that the cost of repair can be correlated to the duration of the neglect.

MasterTemp 250 SFS error jumps from 330 to over 480

Heater is about 2 years old, and yes, I've read a lot that seems to point to a bad SFS. Already have that part on order :)
I've had to replace them in brand new heaters from that time period. Pentair admitted to me that they had a bad batch, even said to purchase two or three when doing a repair and take the "new" bad one(s) back.
