You may have iron but not enough to oxidize and turn the water brown. I am assuming you had to top off the water to get the pool up and running. Do you have any recent test results? If you are passing the OCLT then I would try adding some sequestrant and see if clears the water. What I think...

What size is his pool? Is it in ground or above ground? He is probably going to need to slam the pool but a little more info about it will help us guide the process better. Is he willing to join TFP and let us help him directly? He will need a recommended test kit in order to complete the...

Hi, welcome to TFP! Your pH is toward the high end so I would just keep an eye on it. Test the TA weekly and adjust if you pH goes higher or starts making big swings higher or lower. I would try to keep the FC at 6, so I don't consider that high, especially during swim season. You don't want...

Hi, welcome to TFP! If your pH is stable then there is no reason to mess with the TA. Each pool has its own "sweet spot" that it likes and yours happens to be 50. Just keep an eye on it by testing the TA weekly and only adjust it if the pH starts making wild swings up or down.

Try cleaning up the white stuff and remove the skimmer so you can see what kind of shape the metal is in. If it looks like corrosion that goes all the way through the metal then I wouldn't risk a repair. If you look in my signature under this post there is a link to the demise of my 21 foot...

Hi, welcome to TFP! It looks like there may have been some fiberglass patch applied on the steps in the past. Usually with a fiberglass pool, resurfacing is done by applying a new gelcoat. @Texas Splash can you give more information?

I think the condition of the wall at the skimmer will be the make or break point. Is the black on the pool wall paint or some kind of padding?

Hi, welcome to TFP! Where are the other holes located? Has the skimmer leak been repaired as well?

A bad spider gasket can prevent the valve from operating smoothly and properly. For example it may not completely seal off the chamber between filtration and waste so that water is circulating through both routes. A common sign of a bad spider gasket is water leaking from the waste port while...

By the way as long as you store your Drytec in a cool dry area it should keep for years and you can use it when it is practical to do so.

Look at the label on your Drytec. From what I saw online it has calcium hypochlorite. CYA (cyanuric acid) and calcium hypochlorite are not compatible chemicals so it will not contain both. FYI never combine CYA and cal-hypo in the same container. It will start a fire! You can't even use...

Hi, welcome to TFP! Yes a bad multiport valve can cause this. It could also be that the wrong size sand was used, the filter was overfilled, or sand got into the stand pipe. Laterals can also be damaged when putting sand in if one is not careful. Open up the filter and check the sand level...

Hi, welcome to TFP! No dissolving powdered shock in water would not be the same. The reason liquid chlorine is better is because it does not come with CYA (like dichlor and trichlor) or calcium (calcium hypochlorite). Both CYA and calcium are needed in a pool but only a set amount. Too much...

The gasket is supposed to "sandwich" the pool and liner to prevent leaks

Try deep cleaning your sand filter before you swap out your sand. As long as the flocc didn't bind to your sand a deep clean will usually resolve filtration issues. Deep Cleaning a Sand Filter

Have you pulled the rest of the liner off the wall to see what kind of shape it is in? Outside my pool wall only showed rust in a relatively small area. The inside of the wall was much worse all the way around. There is a link to the demise of my pool in my signature. Patching the rust will...

Is your butterfly gasket covering the inside and outside of the pool wall? It would be gasket-liner-pool wall-gasket. Does the leak get worse if you back off the screws a 1/2 turn?

Something else you can try is adding silicone pool lube to the o-ring on the pump pot lid. That can make the pot lid easier to get on and off and seal any tiny air gaps between the pot lid and pot.

Hi, welcome to TFP! Could you post a photo of the problem area?

Hi, welcome to TFP! If you have and air leak it will be on the suction side, between the pool and the pump. Anything after the pump would be the pressure side and cause the water to be forced out instead of pulling air in. Make sure the pool is filled between 1/2 and 3/4 the way up the...

Just keep at the slam then. Sounds like you are making good progress.

Do you see any accumulations of pollen on outside surfaces? Run a white paper towel across and outside furniture or objects that stay outside. Any yellow there? If it is only accumulating at the water line it is probably pollen. Is it evenly distributed around the pool or just in one area?

Hi, welcome to TFP! The garden grade stuff will eventually filter out. Flocc requires that you vacuum to waste. Odds are you will be vacuuming out accumulations of flocc several mornings in a row if you use it. You could just keep the pump off overnight and vacuum to waste in the morning...

Thank you for your kind words and support!

It is safe to swim at slam level, however we don't recommend swimming until the water is clear enough to see the bottom of the pool. We want you to be able to tell if someone gets in trouble in the deep end so you can find them easily and get them out. Not trying to employ scare tactics, but...

Hi, welcome to TFP! Do you happen to have well water? Also the active ingrediants in Staintrine are effective against calcium scale formation but not copper. Here is a link to the safety data sheet. https://www.ipshawaii.com/wp-content/uploads/2020/07/APPLIED-BIOCHEMISTS-STAINTRINE-1.pdf

Hi, welcome to TFP! I would not try to epoxy it together unless you can take out the threaded piece from the filter body. If you try to epoxy it in place you may not be able to remove it when the new part comes in. I would set the filter to recirculate to keep the water circulating through...

Ok, I want you to add enough liquid chlorine to reach 10 ppm and let the pump run to mix it in. After 15 minutes check the FC. If you have lost more than 1/2 the FC in that time you will need to follow the process, only check the FC every 15 minutes and to back to slam level until the FC...

Hi, welcome to TFP! I have a couple of questions for you. How did you add the CYA? Did you use granules or liquid CYA? What are you using to test your pool?

The blue sticker will have the serial number. The sticker you posted doesn't have that. I think your actual model number may be different than what you posted so I wanted to use the serial number to track it down.
