low ph

I have a Pentair MasterTemp 400K BTU Heater that is under warranty (pool startup was Thanksgiving 2021...so ~21 months ago). It recently started leaking, and the technician came out yesterday and confirmed that it is totaled. He pulled off the heater manifold, and the copper tubing had corroded...

I recently took on a commercial pool and have been running into trouble maintaining proper balance. The site has 2 Stenner pumps, one for chlorine and one for acid, which I diluted today 1 to 1. I have the chlorine pump set at it's max setting and the acid pump at it's lowest but every time I...

So I went on vacation and I assume within a couple of days of returning my flow sensor got chewed through. Chlorine was at .05. No green or visible algae, but I'm sure it's there. I repaired it and set it to super chlorinate until I could pick up some liquid chlorine (sodium hypochlorite 12.5%)...

So I was gifted a use intex pool (10' by 30") and I shocked it yesterday using 2.4 ounces of clorox pool shock plus, and this morning I tested the water and the chlorine levels are still 0, but the PH has suddenly dropped. Yesterday when I tested the chlorine was 0, and ph was 7.2. But today...

Hey everyone. I'm new to the forum. I'm heading into my fifth year as a pool owner but still consider myself very much a novice. For the first 1-2 years, I hired a company to do my pool care. Then, a neighbor taught me basic water balancing. I bought some test strips, and some chlorine...

Dear all, I'm hoping for some advice. Pool was down for a week due to leak repair, unable to run filter/add chemicals/open cover. At start of season I blew thru 25 lbs of Powder Plus shock 73% Cal-Hypo trying to get CC gone (never could, but did get it below 0.5). Purchased home w/ pool last...

First time pool owner. This morning I finally get the K-2006 test kit and did the first test, here is the result: 12x32 inground, sand filter, vinyl, not very sure about the volume, one store shows 79939 liters, other shows 61203 liters, but I guess it will about 20k gal? Cannot see the bottom...

Summary: Out of the tap my water has low-ish pH (7.2) and high TA (120). The TA has been stable but the pH keeps dropping. over the past 6 weeks I keep adding borax to raise pH but not affect TA and it works, but then after a week or two the pH drops again. I've scoured the TFP forums and Google...

Attached a pic of my readings from SureTREAT app (sorry folks, I prefer it to pool math). I thought I remembered reading recently that shock should be added in evening and SB added in the morning, but never together - is that correct? First time poster but have been searching and reading for awhile!

Hello all. About a week and a half ago I opened my 24' round by 54" deep above ground pool and started trying to balance it. Last week the local pool store tested my water and had me add 25 pounds of Maintain Pro alkalinity increase. Now my TA is at the top of the test limit, 240. My pH is...

Hello, I am brand new pool owner and this is my first pool. Thank you all for your help. So I bought a house and did not get to the pool till after a month without any pool service. I checked the chemistry and found the pH to be very low (6.8). I added 15 lbs. of soda ash in one go and have not...

Hi. New here, having some trouble with my chemistry (low PH, high TA). I have a 21,000 gallon pebbletec pool. I heat it, min temp is 83 but its now going over that in the daytime as it heats up here in Arizona. So temp is about 85 or 86 now during the day. My stats are this at the moment...
