Water in tube that goes down below pool?

I’m we’ve had a bunch of rain here in TX and I remember our pool builder saying they installed a tube to view if there is water u see Fiberglass shell. Does anyone know what this is called?

I looked down it tonight after I got home from work and there is water that has collected at the bottom. Not sure if this should be a cause for concern?

Thought on this Salinity MA

I mistakenly ended up with a gallon of this stuff from my local Pinch a Penny here in Texas. It was on the counter and the cashier had rang it up before I noticed it wasn't the usual Champion brand acid I get there. Upon questioning, they assured me it was "just as good as the other stuff", but I was immediately skeptical since I could not find an actual strength % listed on the bottle, which was a huge red flag.

After using up most of the bottle, I can confirm this stuff is definitely not full strength and does not have the same impact on my pool's pH as every other full strength 31.45% acid I've ever used. I'm having to use about twice as much to get the same effect. Wasted money. I won't be buying that stuff again.

I'm surprised they'd just swap one product for another like that, because it will absolutely have an impact on their customers' pool chemistry, and not for the better. I noticed "Suncoast" on the label (visible in photo in first post), and that seems to be their in-house brand, so my guess is they are just switching to their own in-house brand acid.

They will also identify, pressure test, and install equipment as listed in the picture. I just want to make sure everything on there is necessary?
He is going to try and get my old light working for a couple hundred bucks, but if not, should I just filling in and use wireless lights?
In line chlorinator actually needed?
Polaris, should I just buy and install myself?
Bead blasting tile, can I just pressure wash and scrub it?
Have them specify the MODEL # of the filter, pump.
Get the largest filter you can afford. Many year like the Pentair Clean&Clear PLUS, or Waterway in either 420 or 520.
Get an intelliflo3 VARIABLE speed pump. The 3hp is nice. Then you don't need a timeclock, and VSP will save you $$ on your electric bill.
Ditch the chlorinator. Quickest way to kill a heater, and they are expensive. Have them quote a salt water chlorine generator that is 2x the pool volume.
Boost pump/pressure side cleaner is not in my wheelhouse. Some like them some don't. Booster pumps are an added cost and maintenance. Might consider, not a recommendation, a robot.

Be careful on the bead blasting:

In general with any kind of blasting work, you want to match the blasting media so that it is as hard or harder than the material you want to remove but not so hard that it damages the underlying substrate. As you can see from above, the kierserite and glass beads will satisfy the first criteria BUT the glass beads can also cut into the tile glaze.

Help! New pool owner planning equipment pad remodel/replumbing

What do you think of this layout? Mind you nothing is square yet as I just wanted to see the rough positioning of everything. I was a bit disappointed not to use the jandy 3-ways in their original configuration (with the "inlet" in the middle of the tee) but I opted to try and keep it simple and minimize 90s/fittings.

Ok, so I originally thought I would do this myself, but we got a couple quotes and they weren't too scary.. but I want to make sure I'm not missing anything ir getting anything I don't need

About 8 years ago we covered the pool, and cut out the equipment, burying it at ground level.

We got a quote to knock out the hallow spots and re plaster. We plan to use the 2nd plaster option.

Anything else I should ask about or include?

Sick of pool store not knowing what they're talking about, selling me stuff.
Someone call me? Seems like it, but you are in good hands with Marty.

You are not alone, welcome to #teamPoolStored...Post up your experience...

Trying to Get Rid of the Pool Cleaning Blues with Robotic Cleaner

Get pool math. Use your TFP UName/PW.
Configure your pool.
Then under the gear in the upper right, scroll to the bottom and share with TFP (then we can see your logs, click my name you can see mine)
Then go to menu (upper right) and use "Effects of Adding."

After you are setup, tell me how much adds 5ppm
I am not even sure my pool is 30000 gallons. I measured it once, and seems that, since it has a slope from shallow end to the deep end, that it's only about 25,000 gallons.

I have chlorine pool now, but am thinking of purchasing a CircuPool RJ-45 next year. For now, I think the best kit will be the TF-Pro? If so, I will order one tonight. $150, but if it works it
will be worth the cost.

Mixed Instructions - VS Pump & SWG

hey everyone, i've been reading and seeing mixed messages on this and am looking for clarity.

I am about to install a Circupool 3.0 hp smartflo VS pump alongside a Core-Control 55 salt gen.

many it seems use the aux option on their pumps to drive the salt gen...but i dont think the circupool pump has that. Please correct me if it does and i can't find it in the manual.

Discount salt pool recommended i buy a plug in timer to make sure the salt gen only gets power certain hours per day primarily when the pump is in lower speeds and not when it first turns on. Is this ideal?

Others have said the salt gen is smart enough to just stay on and plugged in....will it be more wear and tear on it just letting it have power full time? So even when the pump turns off it wont sense flow (i know it has a flow sensor) it just wont activate itself...but i think DSP was trying to say it might save components in the salt gen only being on 12 hours per day versus 24/7.

Thoughts on this? What do others do? I'd love to hear from someone that has the same pump/SWG combo...

Thank you!

ok, after much research, i still need help knowing which UV system to purchase/install

TL/DR - low pressure mercury or mercury-amalgam bulbs are your best bet.

For a residential pool turn-key system, you’re most likely only going to find low pressure UV lamps as the standard. They are safer to operate and they produce mostly UV-C radiation and lots of heat (about 30-40% of the electrical energy is converted to UV-C, the rest is longer wavelength visible, heat, and electrical loss).

What’s key is how the UV is implemented. In a standard, single pass, straight flow design, you really need a bypass plumbing configuration to control flow and ensure as much exposure as possible. This does incur a dilution effect because you’re only exposing a fraction of the water flow to the UV source. This can be a good enough setup if you plan to run the UV continuously.

A more efficient approach is to use a larger contact tank setup where the water enters the tank from the bottom and has to flow in a centrifugal fashion so it has a long contact time with the UV source. Some of these systems are setup to inject peroxide as well so that you get the added benefit of hydroxyl radical formation.

Your biggest expense is going to be bulb replacement as they only last a year or so with constant use. So whatever route you chose, make sure you have a few bulb suppliers available. Also, grab an extra quartz sheath tub as well because those lose transparency over time too.
The second scenario you suggested with a tank set up. Is there a plug-play option on the market like that? Or is that something that has to be designed? In our small town there is nobody that knows anything about UV. I guess they are pretty common wasted upsells for many areas of the country, but they are unheard of for pools here.
