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.
The Salifert Test Kit is sufficiently accurate to monitor minor pH fluctuations. Sufficient for 50 tests.
For marine water only.

$17.00The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker® HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate.
