pH is an important water parameter that needs to be monitored and adjusted in both saltwater and freshwater aquariums, but it can be difficult to keep track of and adjust.

pH can fluctuate for a number of reasons, such as changes in the source water, the addition of buffers or supplements, or simply a natural variation. If your pH isn’t where you want it to be, it can be tough to get it back on track.

Seachem Prime is a powerful water conditioner that not only neutralizes chlorine and chloramine but shouldn’t impact pH when added.

By using Prime to condition your water you’ll help ensure that your pH stays stable, keeping your aquarium healthy and looking great.

The pH level of your aquarium’s water is a critical aspect to maintain and adjust in both saltwater and freshwater aquariums.

Too high or low pH can cause fish stress and illness.
