I have a hot tub and everytime I test the water the Ph if very low. The chemical to bring the Ph up is very expensive. Does anyone know of a product I can use to raise the Ph- perhaps something commonly found in the home that would be safe to put in a hot tub. Please - serious answers only.

Invite a bunch of kids into your hottub, they should raise the PH level! jk
"sodium bicarbonate or baking soda raises the kH and pH as mentioned by Goldy. As mentioned, at low pH, the good bugs do not thrive well and the filtration suffers. A pH level between 7.0 to 8.0 would be good. pH should not be raised suddenly to prevent pH shock. Therefore baking soda should be added little by little over a few days. A dosage of 25-50g per 1000L per day until the desired pH is achieved should be OK. As it is easily soluble in water, dissolve it in a pail of water and distribute evenly over the pond. It may need to be replenished after sometime depending on the stocking level as it is being used up by the filter. A more permanent solution of maintaining alkaline pH is to use shells (oyster, cockle) as pH buffers. They act by releasing carbonates slowly.
If the ammonia level in the pond is very low, there shouldn't be much danger in raising the pH slightly. As for the location of the UV, I would prefer to place it at the last stage of filtration, that is after the biomedia, and in a separate chamber."

Buy non-commercial chemicals is my first thought. Oh, serious answers only, woops, here's the serious part:
So, raising the Ph is more acid or more base?
Add acidic things, maybe lemon juice or vinegar
or Add base things like soap, dish cleaner
Add a little, test the Ph, the adjust as needed, but test often and always be sure the Ph is right BEFORE you go in.
The problem with the non-commercial stuff is sometimes it takes a lot to get the job done and it may cost more in the long run.
wait, this is a hot tub? Drain it and re fill!

If the ph is low, that means the water is acidic. Since you want to raise the ph, you need to add something basic to the water. Not sure how well it would work, but you could try some baking soda.
My limited knowldege of this comes from keeping freshwater aquariums. If you try the baking soda, test it out in small quanties first. It might just make your water really hard and not that much higher in ph. But it might be worth a shot.

Baking soda
Oven cleaners that are primarily NaOH
Antacid tablets (mostly CaCO2)
These are all "basic" compounds which will raise the pH of water. I wouldn't use the oven cleaner because of possibly affecting you or your tub, but the baking soda should be safe.
You could also go to a garden store and get big bags of lime. Again, I don't know if that is approved for your hot-tup filter, pump, etc but it is pretty benign and will definately raise the pH.

I just want to correct a few misunderstandings in the answers here.
Acids have low PH's, like 1-6, water is neutral (7), and bases have high PH's, like 8-14. The PH scale ranges from 1-14. The poster wants to make it higher, meaning the water is too acidic. You could add things like baking soda or lye.

Some of the simplest things you could do would be to add salt or soap to the water. Normal water pH is 7. Salt water pH is 8. Soapy dish water has a pH of 12. High pH means you have a basic mixture, while low pH means you have an acidic mixture. Please note though that very soapy water could cause irritation if you have sensitive skin.

Baking Soda

The professional chemical IS baking soda. Sodium Hydrogen Carbonate and Sodium Bicarbonate are the same thing.

you know if you Ph level is under 7 then the product ur using is very acid, which might be hazardous for your skin. i dont know of any product you could use but, water has a high Ph level i think close to 14 so u might wanna consider it...

Your local hardware store should have Ph increaser, or check ace hardware online. I just bought some the other day and it was around $12.00.
