HOW DO I RAISE PH IN MY AQUAPONICS SYSTEM?

To raise pH, we recommend using calcium carbonate and potassium carbonate (AquaUp), and either alternating between them or adding equal amounts of each at the same time. We prefer to use these carbonate compounds instead of hydroxide compounds (calcium hydroxide and potassium hydroxide) for several reasons. First, they add to the strength of our […]

HOW DO I LOWER PH IN MY AQUAPONICS SYSTEM?

So what do you do if you need to take the pH down in your aquaponics system? To lower pH we recommend certain acids, such as nitric, muriatic, and phosphoric. Our preference is phosphoric (AquaDown) because it is the safest of the three acids (it is an ingredient in cola drinks) and it adds […]

HOW WILL PH CHANGE OVER THE LIFE OF MY AQUAPONICS SYSTEM?

Most water comes out of the tap at pH levels above a neutral 7.0. This is because municipalities are concerned about the long-term corrosive effects of acidic water so they adjust accordingly. If your system water comes from a well, you will probably discover the same thing, but in this case, it is the mineral […]

WHAT PH SHOULD I TARGET?

Aquaponic pH management is a bit tricky because there are three living constituencies to consider in an aquaponics ecosystem: Plants, Fish and Bacteria. While the plants generally prefer a slightly acidic pH (5.8-6.2), the fish and bacteria prefer a slightly alkaline pH (7.0-7.6). Therefore, pH management in aquaponics is an exercise in compromise between the […]
