Supplied ready to plumb and play, the reactor comes complete with 6 ammonia-blocking pods and is ideal for new pond setups or for use in established systems requiring extra ammonia control.

The pods gradually dissolve over a 12-week period, providing consistent performance while allowing your pond’s biological filtration to mature naturally. Whether you’re preparing a brand-new koi pond, managing a holiday absence, or simply adding extra security during seasonal stress, the RP Pond Reactor delivers peace of mind and healthy water conditions.

Water testing products are the starting point for most pond treatment decisions. Accurate test results help show whether the issue is ammonia, nitrite, pH, KH, phosphate, chlorine, nitrate or another water parameter. This avoids guessing, reduces unnecessary dosing and gives a clearer record of how the pond responds after treatment, water changes or filter maintenance.

Testing guidance
