Product Details

In a properly functioning aquaponics system, the pH naturally falls.  This is caused by the activity of the bacteria that break down the fish wastes into plant food.

The ideal pH range for an aquaponics system is 6.2 to 7.  When pH gets down to about 6.4, it's time to start adding some buffer - that is, an agent that will raise the pH back up to the higher end of the good range - like potassium bicarbonate!

As well as raising the pH, potassium bicarbonate (KHCO3) also adds some potassium (K) to the system, which is necessary to plants but not produced by the aquaponics system itself.  Fruiting plants like tomatoes and cucumbers particularly need potassium.

This potassium bicarbonate comes as fine crystals that readily dissolve in water.  Mix the necessary amount (instructions on pack) with some water and add the slurry to the system at the farthest point from the fish tank; under the water inlet to the farthest media bed is a great place to put it.

When adjusting the system pH, GO SLOWLY!  Never try to make large adjustments quickly; that can shock your fish.

Once your system is up and running, buffering (raising) the pH becomes a routine part of your maintenance schedule, so keep some potassium bicarb on hand!

As long as you keep it dry, it lasts for years, so why not stock up today?
