Seachem Discus Buffer

Discus Buffer is a dry buffer used to move an aquarium toward the soft, acidic water that discus and other blackwater fish come from, and to hold it there.

Key features

• Lowers pH and resists it drifting back up, which is the harder half of the job in hard tap water.
• Softens water by precipitating calcium and magnesium, so it acts on hardness as well as on pH.
• Intended for discus, and equally relevant to other soft-water species such as many South American tetras and dwarf cichlids.

Using it safely

• Move slowly. A sudden pH swing is more dangerous to fish than a steady reading that is not quite ideal, so adjust across days rather than in one dose.
• Where you can, buffer new water in a bucket before it enters the tank instead of dosing the display directly.
• Test before and after every adjustment. Working blind with a buffer is how tanks crash.
• Target range and dose rate are printed on the container. Follow those, and ask us if you are unsure what your water is doing.
