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
A low pH can be corrected by improving aeration and by increasing the alkalinity using the Salifert KH + pH buffer additive.
The Salifert Test Kit is sufficiently accurate to monitor minor pH fluctuations and is scaled from pH 7.4 - 8.7.
Sufficient for 50 tests - For marine water only!
