Salifert pH Profi-Test Kit
The pH value in a marine tank has a major impact on the growth of corals and calcareous algae and on many biological processes. The pH should not be allowed to fluctuate more than approx. 0.2 units during any 24 hour period and should preferably be kept above 8.2. If the pH is too low then the cause may be a too low alkalinity and/or a build up of carbon dioxide caused by insufficient aeration. The Salifert Test Kit is sufficiently accurate to monitor minor pH fluctuations and is scaled from pH 7.4 to 8.7. Sufficient for 50 tests. For marine water only!

The pH test results are very reliable and easy to read. I’ve used it regularly to maintain stable pH levels in my reef tank. The kit lasts for about 50 tests, which is enough for a typical weekly testing schedule.

It’s accurate and helps me catch small pH drops early. I noticed a drop in alkalinity after adding new coral, and the test kit helped me adjust my aeration.

Simple to use and gives clear results. I appreciate the pH range from 7.4 to 8.7, which matches my tank’s needs. It’s a must-have for any marine aquarium keeper.
