Most ph mysteries in aquaponic systems boil down to how hard the water in your system is. this hardness dictates the buffering capacity of water. water from most sources has some level of mineral salts dissolved in it (purified water such as distilled or reverse osmosis-filtered water are exceptions).. To bring ph down, you need to make sure there is nothing in your system buffering the ph up (if there is concrete, mortar, limestone, marble or shells in your system and you try to bring the ph down using acid you will simply cause ph bouncing because as soon as the acid brings the ph below the buffer level of the material, it will begin to. Ph and water hardness in your aquaponics system. let’s say you have a ph of 8.0 in your aquaponics system and you would like to bring it down to 7.0. the more resistant your system will be to attempts to alter ph. having a higher kh level can be beneficial in a fully cycled system because the nitrification process produces nitric acid.
In this video, aquaponics expert dr. nate storey discusses ways to bring up ph levels in your aquaponics system. find more aquaponics information here: http:... skip navigation. Using the ph test kit, test the ph level of the water circulating through your aquaponics system. the redder the strip or water the more acidic the water. acidic water is not conducive to plant and fish life, so the ph level must be raised in this case.. You should target a ph between 6.8-7.0 in your aquaponics system. if the ph level drops below 6.6, the best way to raise it is to use hydrated lime (calcium hydroxide), potassium carbonate or biocarbonate..
