The level of ph in water determines the solubility of nutrients like phosphorous nitrogen and carbon constituents and also that of heavy metals like lead copper and cadmium which are toxic and more soluble at lower ph levels.
What to use to lower ph in water.
Read your ph level and compare that to the ideal ph for the type of plant you re growing to determine whether you need to raise or lower the ph of the growing medium.
The ph of solutions can be altered by adding acids and bases.
It is typically used to clean bricks.
For houseplant or gardening water mix 1 tablespoon 15 ml of white vinegar with 1 gallon 4 liters of water which can help bring a ph of 7 5 7 7 down to around 5 8 6 0.
The basic ph scale runs from zero to 14.
Hydrochloric acid also known as muriatic acid lowers ph levels in water.
To lower the ph in larger areas i would use elemental sulphur if i wasn t in a rush but usually you do want the benefit within that growing season.
If you put too much acid into a solution you will have to use a base to raise the ph once again.
Hydrochloric acid is a dangerous substance.
If you blindly mix an acid with water you are unlikely to add the correct amount.
Typically you use acids to lower the ph level in your water.

You can purchase muriatic acid at most hardware stores.
Lower the ph of the water by measuring out four cups of vinegar and pouring it directly into the water.
If you choose to use a sodium bisulfate product to lower your ph or alkalinity levels be sure to use some precautions.
You should bare this in mind depending on the end use of the water as this will affect anyone consuming such water directly or indirectly.
Try not to use it on a windy day so that the powder won t blow back onto your skin or eyes and get down close to the water when adding it to get as much of the product into the pool as you can rather than into the air.
Pure water is often well balanced with a ph of seven but the normal ph range for tap water is 6 5 to 8 5 meaning water can run slightly acidic or alkaline.
In which case i would choose iron sulphate as my first choice this will help to reduce aluminium toxicity in the soil and if i couldn t get that then my second choice would be aluminium sulphate.
