Reefkeeping and aquariums are vitally dependent upon water quality. If you are serious about your aquarium, you will not try and cut corners on the quality of your water. Nothing will ensure your success with a reefkeeping or a fresh-water aquarium or salt-water aquarium, or any reefkeeping system as much as the quality of your water. Reverse Osmosis and Deionization are frequently used together to produce water which has no dissolved solids for reefkeeping systems. Some people just use deionization (also called DI) for reefkeeping water, but the cost is astounding unless you use reverse osmosis (RO) as pre-treatment. As always, it is highly recommended that you do a water analysis before ordering a water system for reefkeeping or aquarium purposes.
