Best Reverse Osmosis Review and Guide

In fish farming, the need arises for to ‘detoxify’ the water from substances and elements that is detrimental to the health of the fishes. For this reason, working directly with tap or well water doesn’t just cut it. This is because experiments have shown that these kinds of water contain substances like nitrates, phosphates, chlorine, heavy metals, silicates and other elements that are not suitable for aquarium lives. This problem leads us to the concept called reverse osmosis.

Best Reverse Osmosis Review and Guide

Definition of Reverse Osmosis (Ro)

In natural processes, it is expected that the stronger of two forces usually wins and usurp the weaker force. This is seen in a process called osmosis. It is the movement of molecules of a solvent through a semi permeable membrane from a less concentrated solution into a more concentrated one.

Likewise, reverse osmosis is a process that aims to move molecules from a more concentrated solution to a less concentrated one by applying pressure on the later. This simply means that external pressure/forces are brought in so that the weaker of the forces wins. It is through this method that the elements and substances in tap or well water are purified and made wholesome for aquatic lives. The tap or well water is forced through a semi-permeable membrane under pressure, leaving behind contaminating and large particles so that only the cleanest water is collected.

Major Problem with RO Water

There is often a downside to everything good and reverse osmosis is no less. Because RO water is 99.9% clean, it is no longer hard or alkaline and all traces of elements – even those beneficial for microbial activities have been wiped out. And since all fishes need a degree of hardness and alkalinity to maintain PH levels in water, RO water would not suffice.

Two processes have been identified as a way to overcome this problem:

  • One involves mixing the RO water with a portion of tap water in a bid to put back some of the elements extracted from it. However, getting the right proportion is on a trial and error process; plus doing that defeats the initial process of reverse osmosis.
  • Another involves re-mineralizing. It involves adding essential salts and minerals into the RO water in the right proportion. They are re-mineralizing products available in the market with some already proportioned for use by specific fishes. The fish keeper can personally apply the product in mix proportions as directed by the manufacturers.

Whichever method works for you, the goal is to create suitable water condition for habitation by our precious fishes.
