Freshwater Aquarium Buffers and Carbonates
Freshwater buffers & carbonates adjust the alkalinity, hardness and/or pH of your water, and aid in buffering (keeping levels stable despite changing conditions). This is crucial to the survival of aquatic life, and these levels should always be monitored.
Most freshwater buffers produce longer lasting pH adjustments than pH regulators and maintain stability better as well. You'll find quality freshwater buffers below for general freshwater tropical conditions, rift lake conditions and black water rainforest conditions to simulate these unique environments. Substrates like crushed coral can also be used if harder water is desired.
