OCLT good…but algae still in pool

My question is, at some point will the SLAM rid the pool of the stuff I’m stirring up? Or maybe the filter is supposed to catch it?
Yes. How often are you brushing? Did you scrub behind the light? Under the drain covers?

Do me a solid and retest your CYA using these instructions:

Hayward Sand Filter Sand Screen Under Drain Broken and Stuck

Easy solution: Turn the filter cavity upside down so the drain plug is facing straight up in the air. It's easier if you set it on a 50 gallon trash can, if you can. Put a little bit of penetrating spray around the rim just a little though. Then take a heat gun and slowly warm up the outside of the drain. Be careful not to heat it up too much but just enough to get it warm that you see some of the penetrating oil start to go down inside and then take a pair of needle nose pliers with whatever left inside and spread them and work slowly counter clockwise and it should come out pretty easy.

CH Increasing + White Spots on Plaster

I tried calling the pool contractor twice today, starting before lunch. Both times, a very cheerful receptionist answered on the first ring, but I hit a snag when the receptionist took my info & transferred me to a manager. The first time I waited on hold for 15 min to no avail, and the second time I left my info for a call back, but that was hours ago, the store is closed for the day, and- big shock- no one called me back. I guess I’m in for a bit of a slog with them, which really isn’t a shock because we had some issues during the remodel, and I was hoping not to have to deal with them again. I’ve already gotten the “these are tough times to work in” and “it’s hard to find good help” spiels.

I’ve been reading all the resources y’all posted, and I’m quite confident that the spots in my plaster are not something that we caused. I’m sure the contractor will try to say it was us, though. So I’m looking for some tips on how to handle the upcoming negotiations.

1. Is there any reasonable scenario in which WE could have caused the white depressions/pits in our plaster, considering our PoolMath records? PoolMath Logs

2. The plasterer gave us a 3 year delamination warranty. Is this something that should be covered under that?

3. I know that NPT has very strict guidelines for maintaining plaster (specifically not allowing a negative LSI EVER)- Suppose the contractor looks at my PoolMath records and claims that I’ve messed up the plaster because my LSI has very occasionally been negative. How should I respond? I know that my chemistries have been just fine and that even on the occasions they’ve dropped below 0, they have haven’t been negative enough or kept there long enough to cause problems, but I don’t have a good way of “convincing” the contractor of all that.

4. Any other tips for dealing with a less than willing contractor?

I'm going to lose my mind - plug stuck in skimmer pipe

Seems like you should be able to push it out with something like a plumbing snake. Or get an endoscope (https://www.amazon.com/Teslong-Bore...-lpcontext&ref_=fplfs&smid=AFI3X2X3YFS02&th=1) to see where it is, then dig out the pipe only in that spot and do a local repair.
Generally speaking you might be better off with a normal plumber instead of a pool guy.

Any ideas what could cause this

Hi there,
I have had an above ground pool for what will be the third year, I live in Ohio so the pool is only used 4-6 months. I have a Raypak heater 156 A. I was opening the pool and the heater fired right up and was working. I turn the pump off and there was a gurgling sound and it split the water hose going into the heater from the pump spraying boiling water into the air, I thought maybe it was a fluke and bought a new hose and it did the same thing. Turn the pump off, gurgling noise from heater and so much water pressure it split the line. I have attached picture. Heat exchanger had some minor build up on it but have cleaned. Not sure what else the issue could be???

Aiper Scuba S1 Review

Folks,

Bad news again! I bought my S1 06 July '24. Sadly it was resting 5' from the wall yesterday with the red light blinking.
Ah bummer. I had high hopes. I guess katodude had the right idea - get it on sale - buy the warranty and be able to justify the cost over the warranty period and assume it won’t outlast the warranty.

Disappointing…

OCLT good…but algae still in pool

in ground pool. Full tx sun.
Pebble finish
SWG (currently off)
Spa overflow, 3 fountains and 2 vertical bubble columns. All running during the SLAM
CYA is 50
Ph of 7.2 at start of SLAM
Maintaining SLAM FC of 20ppm.

I lost 1.0 ppm of FC overnight, but I still have yellow mustard algae on the walls and floor. So, the SLAM will continue.

I’ve been at this for several days now and I’m shocked how much Crud I still stir up when brushing.
My question is, at some point will the SLAM rid the pool of the stuff I’m stirring up? Or maybe the filter is supposed to catch it?

Thanks

Dolphin done rubbed the pattern off my liner

My pool/liner/Dolphin S300i are all just coming up on 4.5 years old. Overall the Dolphin has done its thing admirably, but last summer or possibly even the year prior we started to see it leaving a consistent wear track around the shallow end where the wall meets the floor at a 90 degree angle, as a result of the tracks rubbing against the floor while starting to climb. We used to run the thing daily in the spring through fall, because - crazy us - we like to have a clean pool but when this started we reduced to minimum necessary as I’m concerned eventually it’ll wear away more than just the printed pattern. I always just sort of assumed this is something you have to deal with when using a track robot with a vinyl liner.

Fast forward to today, I dropped the Dolphin off to be diagnosed for some unrelated behavior that started last year following an electrical surge, and I happened to mention it to the tech who was adamant that this should not happen. So what’s the deal here? Normal or not, if not what could be so special about my setup that would cause this?

Intentionally raising CYA to lower ph ceiling

That should lower the Carbonate Alkalinity enough.

You are probably just worrying too much at the higher pH levels.

If the CSI is good, don't lower the pH.

Maybe get a pH meter to be really sure.

If the pH is below 8.3 and the CSI is below +0.2, then you should just leave the pH where it is.

Many people read the higher pH values as higher than they really are.

Most people over worry about higher pH when they could just leave it alone and do nothing.

Show your pH test and what you think it is.

I have pool math

If I don’t do anything for about a week the ph will rise above 8.0 (Taylor drops) and tops out around 8.2 with a handheld digital ph meter.

At ph of 8.2 the CSI is essentially perfect and close to zero. I would love to just let the ph ride at 8.2 but I’ve never felt confident to do that based on things I’ve read online saying you shouldn’t leave the ph that high.

Does CSI trump everything else?
Is it possible for anything to go wrong if the CSI is normal?

Multiport valve - unused positions

I have a brand new Hayward SP0715XR50 multiport valve, and I'm seeing something strange:

When set to recirculate, water drips out the waste port. And when I open the air bleed on top of my (also brand new, Hayward W3DE6020) filter, water absolutely gushes out of the waste port, along with DE that I had just loaded the filter with. It's as if when the pump and return ports are connected, then the waste and filter ports are too.

Is it possible that not all ports are sealed off when the multiport is set to recirculate? I'd hate to have to tear apart the plumbing to replace a bad multiport valve.

Tips on how to clean intelliPH acid injection fitting ?

No clue, never taken it apart. I think I'd probably try and get something to hook the filter and see if I couldn't get it pulled up through one of the openings, before trying to disassemble the tank.

Seeing that it is pumping without the injectors, I think the filter is probably fine, was just something I thought about and wanted to mention. I'd be looking at what is going on when the injector gets installed. How tight are you screwing down the fittings?

Help a newb

For any CYA level you need to be free and clear of minimum FC at your next test/dose. Sometimes its not 24 hours and its 36 or 48.

But lets do a one day loss with 4 ppm mid season.

Minimum FC
+ 4ppm
+ 1 or 2 wiggle room FC
-------------------
= TFP clear.


4 ppm may last a week in the fall, but 6 hours in July. You adjust the daily target as necessary to achieve the never sniff minimum mission.
