AquaLight osmosis devices & parts
AquaLight osmosis devices are of very good quality. Reverse osmosis water is essentially free of chlorine, nitrates, phosphates and heavy metals. It is ideal for making seawater and for replenishing evaporated aquarium water. Tap water is generally full of these contaminants and the effect on the aquarium can be very serious depending on how the water is in the environment. Using tap water for the aquarium can lead to algae and diatom problems, which must then be treated with other methods.
