Using a reverse osmosis water filter system for aquariums to purify tap water before putting it into your tank is one of the wisest choices a hobbyist can make. Tap and even well water can contain a variety of contaminants that, while safe for human consumption, lead to a variety of issues in an aquarium. Aquarium owners searching for the source of water quality woes and nuisance algae growth often don’t need to look any further than the water they are putting into their tanks.
A RO filter system will differ from the types of aquarium filtration equipment you may are already be familiar with. That is because RO systems filter water before it goes into your tank rather than filtering the water you already have in your aquarium. Most reverse osmosis systems look and operate the same way, so once you understand the various components, how they work and how to maintain them, you’ll pretty much be set regardless of the specific make and model you choose.
For a freshwater aquarium, a standard reverse osmosis system will do the job. For a saltwater fish-only or reef aquarium, a reverse osmosis deionization system is preferred because it will remove nearly all impurities that could potentially harm delicate marine organisms.
RO filter systems should be monitored with a TDS meter so you’ll know precisely when to replace your sediment and carbon filter cartridges as well as the TFC membrane. Since many hobbyists place their RO systems under their kitchen sink, they will often connect a drinking water add-on kit that includes a pressurized reservoir tank to hold the newly purified water. Since RO filtration improves the taste, odor and appearance of water, why not take full advantage?
