Swimming Pool & Hot Tub PH
Swimming Pool & Hot Tub PH
Having just filled the hot tub for the first time and purchased some chlorine from the ferreter'ia, we tested the water to find the PH was through the roof.
So off back to the ferreter'ia for some PH lowering acid.
The man no comprehend, but was sure he did not have any.
We searched all the supermercado's and the Farmacia without any luck.
So the question is 'Where did we find the PH lowing acid'

No, No, No, agua fuerte NO! Especially not in a hot tub. Would you really want to bathe in hydrochloric acid?
What you need is sodium bisulphate, more commonly known as pH menos, minorador de pH or reductor de pH.
It is sold in tubs similar to those in which you buy the chlorine.
If you can't find it in the ferretería and there is no pool shop locally you will find it in most large hypermarkets.

Hydrochloric acid is a well established and well recommended method of reducing pH in pools.
You may choose to use sodium bisulphate but it is not the only way. If fact, doing so, is chemically equivalent to adding Sulphuric acid!
They are both acidic and therefore reduce the alkalinity. Some people prefer to use powdered Sodium Bisulphate as it is less dangerous to store and use. If fact, in the UK it would be impossible to buy Hydrochloric acid at 25% strength in the supermarkets as you can do in Spain.
Once diluted it makes no difference in the pool.

This is a well established method well recommended by the building fraternity, as the damn stuff eats tile grout!
Keep on putting in the agua fuerte, and next year you can invite your friends round to enjoy watching the nice man in the neoprene suit with air tanks on his back, struggling to regrout underwater!
Or, of course, you can drain it, miss out on the frogman, and simply pay 750 € for water to refill...............
Usual rule applies - penny wise, Euro foolish!

Check out all the pool maintenance sites on the Internet and you will find they recommend either Hydrochloric acid or Sodium Bisulphate.

We found the PH acid in the perfume shop of all places in 1 liter bottles. Would have preferred dry acid as my wife is a bit of a pool maintenance buff, having been in pool management for over twenty years in the UK.
She drives me mad sometimes with her constant water testing.
Whats wrong with itching and occasional red blotches, it goes eventually.
