Category 06 · Water testing
Water testing products measure common pond water parameters — pH, ammonia, nitrite, nitrate, KH (carbonate hardness) and GH (general hardness). Liquid reagent kits are generally regarded as more accurate than strip tests, while digital meters provide quicker readings for pH and TDS. This category lists current retailer listings for aquarium and pond water test kits and instruments.
