D-D H2Ocean P4 Dosing Pump

D-D H2Ocean P4 Dosing Pump

As in every industry; complete automation is becoming more and more of a trend in the aquarium trade. Automation makes aquarium maintenance easier and less time consuming. Dosing pumps are one of the newer pieces of equipment on the market that aid in maintaining a consistent aquatic environment by adding precise amounts of additives to the aquarium water on a daily basis, or even multiple times per day. This is particularly useful in reef keeping due to all the differing elements required for healthy coral and reef tank growth. A steady supply of elements like calcium, magnesium and other essentials can be programmed to be added as necessary to stop croal growth slowing down to unnatural levels. You can even use dosing pumps to add freshwater back into the system to compensate for evaporation and prevent increase in salinity levels. 

The H2Ocean dosing pumps from D-D Aquatic Solutions are an innovative smart pump that has been developed along with Kamoer a company who specialsie in the manufacture of medical grade equipment and as such these pumps are extremely reliable. The P4 pumps are compact with a small footprint of only 25x5cm meaning they will fit easily in almost any aquarium cabinet. The P4 pumps provide simple, flexible and precise control of supplement additions through the easy to use D-D H2Ocean mobile app.
