Boost pH levels in your goldfish aquarium
Boost pH by testing KH levels first. Carbonate mineral (KH) acts as only one part of pH with the other part being oxygen. All to often goldfish and Koi keepers use bicarbonate of soda to raise pH without ever testing KH, because they don’t know what KH does. KH gives water the ability to support the O2 molecule. Carbonate mineral alone is responsible for alkalinity
Mixing soda to water that is rich in KH, could raise mineral levels too high, burning the fish. The high pH reading could be based on a high KH
Boost pH
Test KH. The comfort zone varies at 100 to 140 ppm, however, the higher side of the zone is preferred. Whenever KH is found to be low in freshwater source, boost the parameter. The comfort zone for pH is 7.4 to 8.4. Whenever KH is well within the comfort zone, pH levels should be the same, however, if this isn’t the case, oxygen levels must be low for yet another reason
Remove the top of your aquarium
Most all goldfish are kept in enclosed tanks. Water surface must be exposed to fresh air because this is how water breathes
There’s more
Goldfish produce a tremdous amount of waste, and from waste, gas is produced, Whenever the gas is present, it fills the body of water, keeping oxygen from entering. There’s no space for oxygen whenever the water isn’t free of gases.
Raise KH
KH healthy, although pH is low
Using a pitcher, push it deep into the tank water. Bring it to the top and pour it out. Refill and repeat about 10 to 15 times. Test pH. If it’s higher, this tells you a little work needs to be done
