When it comes to keeping fish, pure water is an absolute necessity, and there is no more effective way to filter out the impurities from your tap water that could cause health problems for your pets, than installing a reverse osmosis aquarium system.

Reverse osmosis systems work by removing the calcium and magnesium from hard water, making your water cleaner and purer than the water directly available from the source. These small, but very clever systems force water through a semi-permeable membrane with microscopic holes that filter out 99% of the contaminants and impurities, allowing the clean water molecules to pass through, whilst keeping out the larger mineral molecules.
Many models also include a pre-filter placed before the membrane to remove sediment and other contaminants from the water, which might not be caught by the membrane. It's their compact size, and the fact that they are so thorough in keeping out harmful contaminants, that leads to these systems being so popular in aquariums, with most home aquarium owners using some form of RO aquarium filter to keep their fish healthy.
Tap water might be perfectly safe for humans to consume, but it can contain trace amounts of phosphate, nitrate, chlorine and more aggressive heavy metals that could seriously mess with your aquatic habitat. Nitrate and phosphate can, for example, encourage algae growth in your tank and copper and lead, which can be present due to the pipes used to carry your tap water, can be highly toxic to marine life.
The best reverse osmosis system for your aquarium will depend on the size of your aquarium (the number of gallons of water required per day) and the hardness of your water, but you'll find a number of options here that should suit most situations.
