How to Raise Pool pH: Complete Guide to pH Increaser

Before I dump chemicals into my pool, I'm trying to decide between adding baking soda or actual pH increaser to bring it up from 7.0. The pool store told me I need to raise it, but they mentioned a couple different chemicals and I'm honestly a bit confused about which one to use.

I've heard about soda ash and baking soda, but I'm not sure what the difference is or how much I should add to my 20,000 gallon pool. I really don't want to mess this up and swing it too far the other way. Should I be adding the chemicals slowly, and do I need to have my pump running when I do it? Any guidance would be really appreciated!…more

How to Increase Pool pH: Step-by-Step Guide with Dosing

The pH in my 20,000 gallon inground pool is stuck at 7.0-7.2 and I know that's way too low. I've heard about using different chemicals to bring it up, but I'm not sure which one to choose or how much to use. Some people mention soda ash while others swear by baking soda - what's the difference between these options?

I want to make sure I'm doing this right since I've never had to adjust pH before. Should I be adding chemicals gradually or can I fix it all at once? Also, how long should I wait before testing again to see if it worked? My pool is crystal clear otherwise, so I just need to get the chemistry balanced properly.…more

How to Raise Pool Alkalinity: Complete Step-by-Step Guide

Last week my pool's alkalinity dropped and now I'm trying to decide between sodium bicarbonate and alkalinity increaser to get it back up. I've heard baking soda works but I'm not sure how much to use or what the process actually looks like.

Anyone have a step-by-step on the right amount to add and timing? Want to make sure I don't mess this up and end up with more chemistry issues than I started with!…more

How to Increase Pool Alkalinity Fast - Complete Guide 2026

So there's this pool guy telling me to drain and refill my entire pool just because my alkalinity hit zero, but that sounds like expensive overkill for some cloudy water. Every time I try to balance the pH, it just crashes back down within a day or two.

I've got a 20,000 gallon pool and honestly I'm tired of throwing random chemicals at this problem. What's the RIGHT way to get my alkalinity back up to where it should be? I need specific amounts and steps because clearly what I've been doing isn't working.…more

Can I Shock Pool After Adding Alkalinity? Timing Guide

Walked out to check my 20,000 gallon inground pool after dosing it with sodium bicarbonate this morning to raise alkalinity from 60 ppm to 100 ppm, and now I'm second-guessing my shocking timeline. My pH was sitting at about 7.2 before I added the alkalinity increaser, but I know adding baking soda can bump up the pH as well.

I'm planning to shock the pool tonight since we've had some heavy swimmer load this week and the water is starting to look a bit cloudy. Should I wait a certain amount of time after adding the alkalinity before I shock? I want to make sure the shock is as effective as possible and I've heard that pH levels can affect how well chlorine works.

My current test results show chlorine at 1.5 ppm, alkalinity should now be around 100 ppm, and I'm not sure what the pH has risen to after adding the sodium bicarbonate earlier today.…more

Can I Use Pool pH Increaser in My Spa? Safe Chemical Guide

Noticed I'm always running low on spa pH increaser and wondering if this is a dumb question, but can I just use my pool's pH increaser instead? I have both a pool and a hot tub, and I noticed my spa's pH is running low. I have some pH increaser that I bought for my pool - can I use the same product in my hot tub, or do I need to buy separate chemicals?

The pool store didn't really explain if there's a difference between pool and spa chemicals, and I don't want to mess anything up. If I can use the same pH increaser, do I need to adjust how much I add since the hot tub is obviously much smaller than my pool?…more

How to Raise Pool pH: Step-by-Step Guide for Pool Owners

Woke up to find my pool eating through pH increaser like it's candy and I can't figure out why the levels keep crashing. My pool is approximately 10,000 gallons, and recent testing shows pH has fallen to unacceptable levels requiring adjustment.

What specific chemical should I use, what dosage calculations apply, and what's the proper sequence of steps? I want to ensure I follow proper water chemistry protocols including testing intervals and circulation requirements to achieve accurate results without overcorrection.…more

Why Pool Alkalinity Gets Low: 7 Common Causes & Solutions

Opened my pool this morning and the alkalinity had crashed again — only happens when it's above 85 degrees but stays perfectly normal during cooler weather. My kids swim in it almost daily during summer, so I'm really concerned about whether this is safe for them.

I'm trying to figure out what's causing this so I can fix it properly. We've had a lot of rain lately, and I've been shocking the pool more often because of increased usage. Could these things be making the alkalinity drop? What are the main reasons pool alkalinity gets low, and should I keep the kids out until I get it balanced again?…more

Can I Use Baking Soda for Pool Stabilizer? Chemistry Facts

Planning to add some baking soda to my pool, but there's this sharp chemical tang in the air that makes my eyes water every time I get close. Someone at the pool store mentioned I might need stabilizer, but that stuff is expensive.

I've got a huge box of baking soda at home and I'm wondering - can I just use that instead of buying actual pool stabilizer? They're both white powders that go in the pool, so maybe they do the same thing? I'm really hoping there's a cheaper solution here because I've already spent a fortune this season and I'm getting desperate.…more

Can Pool Chemicals Freeze? Winter Storage Guide 2026

Opened my pool chemical bottles after reading the "store in cool, dry place" instructions, but now my garage is freezing and I'm questioning if they actually mean below 32 degrees. We had an unexpected cold snap last week and temperatures dropped well below freezing in my garage where I keep all my pool supplies. I have both liquid chlorine and powder shock treatments stored out there, plus some other liquid chemicals.

I'm concerned about whether these chemicals are still safe to use when my kids start swimming again in spring. Did the freezing temperatures damage them or make them less effective? I want to make sure the water quality will be perfect and safe for my family. Should I be planning to replace everything, or are some chemicals more resistant to freezing than others?…more

Do I Need pH Up and Down for Pool? Essential pH Guide

My husband casually mentioned that we're the only neighbors who stock both pH Up AND pH Down, and now I'm suspicious the pool store is playing us. That's like $40-50 just for pH adjustment chemicals alone!

Is this just upselling, or do I actually need to keep both products on hand? My pool seems to drift one way or the other pH-wise, but rarely both directions. Looking for some honest advice from people who aren't trying to empty my wallet every time I walk in for supplies.…more

Do Saltwater Pools Need Chemicals? Yes - Here's What You Need

Despite having a 15,000 gallon saltwater pool with a functioning salt system, the pool store keeps pushing $200+ worth of chemicals every month. They keep telling me I need all these pH adjusters, alkalinity boosters, and other expensive stuff on top of the salt. I thought the whole point of going saltwater was to avoid dealing with a bunch of chemicals!

I'm looking to handle this myself and cut down on costs, but I want to make sure I'm not missing something important. Does the salt chlorine generator really only make chlorine? What other chemicals do I actually NEED to keep my water balanced, and what can I skip?…more

Do Intex Pools Need Chemicals? Complete Chemical Guide

Last summer when I finally set up my first Intex Easy Set (12 feet, about 2,400 gallons), I've been completely lost on what chemicals I actually need. The manual mentions using chemicals but doesn't give much detail about what's actually required.

I've been running the filter pump for a few days now, but I'm starting to see some cloudy water and what might be the beginning of algae growth on the walls. Do Intex pools really need the same chemical treatment as regular in-ground pools? What's the minimum I need to keep the water safe for my kids to swim in? I want to make sure I'm doing this right from the start.…more
