Water Testing
We can test your aquarium water for standard parameters, especially important as a double check if you are getting abnormal values at home. If your reagents are past their expiry date, this is a possible source of error.
Measurement electrodes also do not last for ever, a lack of maintenance can shorten their lives and result in erroneous measurements, they should be kept clean and recalibrated from time to time. Test kits are available to check for most critical water parameters.
