Hi there,

PH Buffer for SPA/pool sold by shops 'All-for-SPA and pool' is around $15-20 per kg.

Baking soda sold by New World is $5 per kg.

PH Buffer has active ingredient: 99% sodium bicarbonate.

Baking soda consists of 100% sodium bicarbonate.

So, is there a difference? Can I use baking instead of PH Buffer to increase alkalinity?

from what ive read the that are the same.

What are you trying to achieve? depending on how much you need to increase the ph/alkalinity you might want to look at soda ash

Just a maintenance.

I need to add 17g to increase alkalinity by 10ppm in 1000 liters. Our spa is 1000 liters, so just a regular maintenance to keep it in range.

Thanks for the advice. I'll look into soda ash for the time when I need to replace the water.

if its only a spa then baking soda should be fine, im dealing with 35x the water you are usually.

Of course they aren't, they are the same as the stuff you buy to increase aklanity and ph.
