Probe pH
Keeping pH stable is critically important to healthy coral in a reef aquarium. A stable pH is also less stressful for all the aquarium’s inhabitants.
Monitoring pH not only allows you to tune in desirable parameter stability but also serves as an important warning system to warn you of negative chemistry changes.
Neptune probes will out last most other traditional lab grade probes letting you go longer between calibrations, and having to purchase and replace probes less frequently.
