    Weird ph levels

    My ph levels slowly but continuously rise. I have a raised hot tub that pours into my pool. I like to keep the ph between 7.4-7.6. I have to add a little acid about every 2 weeks. My older brother's pool is almost identical. He lives about 2 miles away. My next-door neighbor and a friend...

    R-0870 powder

    I bought my first TF-100 last spring. A couple of weeks ago I ordered refills. My old R-0870 powder has darkened. The new powder is lighter. Is my old powder still good to use until gone or should I throw it away and go with the lighter powder (or combine them into 1)?

    Muriatic Acid Concentration

    Thanks. I have the waterfall on. ph is up .2 from yesterday and TA down 30. Will do as you said, wait for 7.6 then hit it with the recommended muriatic acid to get back down to 7.0.

    Also, I need a better tutorial for the Pool Math app. I upgraded to premium yesterday. Since I'm starting with a new complete water fill I started a new log. I inputted today's readings but it still shows yesterday's values. I added the reminder to clean the filters but the reminder came up...

    Muriatic Acid Concentration

    Yesterday I added 7 pounds of Calcium Hardness Increaser from Home Depot. My CH was 225. We got about an inch of rain overnight, I tested the water this morning at my CH is lower, 175. I took my sample about 12" deep and the pumps had been on for about an hour. My ph is still low at 7.2...

    Muriatic Acid Concentration

    Also, as I get my ph (which is currently 7.8) back down to 7.0-7.2, how soon will my TA respond and go down? How soon do I retest TA? You helped me with a month ago with issues. I eventually had to empty my pool and start over. My replaster guy came out yesterday and polished the pool, I had...

    Muriatic Acid Concentration

    Hi. I just upgraded to a premium on the app. As I use the pool math app it gives me the option of 14.5% and 29% for muriatic acid. I get this stuff from Home Depot. Should I just use the 29% figures?

    Ph, TA and CH Issues

    Water now: ph: 7.5 TA: 170 I know the TA is still high. Should I address it or just let the pool stabilize for a few days and see if it keeps coming down? Water is clear and I am currently running the pump about 15 hours a day.

    With lower temps and less sunlight, I was hoping to use up the last of the bucket I had since I switched to liquid.

    ok. Thx. I added a little over 1 quart of acid. Will give it time to mix and will check later tonight or in the morning.

    Pool filled, new cartridges installed. No leaks! Now time to get new water numbers right. FC: .25 CC: .25 ph: 8.0 TA: 190 CYA: <20 (close to 0 with all new water from refill) water temp 64 So far I added recommended liquid chlorine at 10% of 1 quart and 3 cups. Will put a couple of 3"...

    Thanks. I just tried to close up the filter without the cartridges in it just so I could circulate the pool. I tried 5 times but the filter would leak. I think the water spray pattern inside was too different without the cartridges in there. The good news is they are supposed to be here by...

    After watching the above youtube video I decided to take off the front manifold to see what condition the copper end connectors looked like. I was happily surprised. They weren't that bad. I will flush each line then reassemble.

    Any reason if I did this that I could inhibit water from flowing through the heater from now on except when I'm using/testing the heater? What ramifications would there be if no water ran through the heater for months at a time?

    I watched this youtube video on opening up the heater and might consider doing this. At least I might open it up today and look inside the heater tub. Anyone ever do this?

    Ph, TA and CH Issues

    Thanks, Tim. I dumped 1.5 gallons of 10% in it on Saturday. The water is pretty cold (50-60 degrees) which should slow down any growth. I will dump another 1/2 gallon in it today. Is there any reason why I can't close the filter back up without the cartridges in it and turn the pump back on...

    To a high enough level that will mess the water up again?

    Ph, TA and CH Issues

    I won't have too much more info for a few more days. I am replacing the filters before I turn the system back on. Amazon had a 4 pack of filters for $160. Leslies had them in stock for $400. I can wait 5 days for that $ difference. Didn't want new refilled water running through the turquoise...

    ok, thanks. Besides the heater leaking I was worried about re-contaminating the pool that I just emptied.

    Ph, TA and CH Issues

    That will be next to impossible to get them to do but thanks for the advise. Is the heat exchanger/copper area of my heater replaceable or will I most likely need an entire new heater? I just replaced that one a couple of years ago. It was $3k+.

    The turquoise does come off but not sure if I can get it all off in between the pleats. Will just replace them.

    I guess technically I haven't added anything since I did a complete refill. Will try to clean one and report back

    You're a genius. I just cleaned these cartridges 3 days ago. They looked cleaner than ever. Thought I'd check them again while the pool is refilling and after dumping all the baking soda and soda ash in there for the last couple of days. I have never seen this before. Are the cartridges...

    Just curious why does Houston have a greater chance of popping out? I completed the drain portion at 10 this morning and immediately started the refill then. Unfortunately, the refill is about as slow as the beginning of my drain. I am filling about 1" an hour. How full does the pool need...

    Started draining around 3pm yesterday and all night. Water dropped about 15" in 15 hours. Went to Home Depot. Rented an immersible pump, $30 for 4 hours. Water dropped 12" in the 1st hour.

    They drained and resurfaced it about a year and a half ago. It was empty for about 5 days during that time. They did poke a few holes in the bottom for some reason. I've drained 8" in 8 hours. I will let it run overnight. If still a long way to go in the morning I will see if Home Depot has...
