Keep your pond water dialed in with the NT Labs PondLab 200 Multi-Test Kit. This comprehensive testing solution gives you 200 combined tests across the 6 critical parameters every koi keeper needs to monitor: ammonia, nitrite, nitrate, pH, GH (general hardness), and KH (carbonate hardness).

The PondLab 200 is the kit we recommend first to every pond owner. One kit, one box, every important parameter — and it's the most cost-effective way to test broadly. If you're going to keep koi or goldfish healthy long-term, this is the kit you want on your shelf.
