Now their are several models to buy to that will accomidate any person from apprtment grower to someone who grow's with a shop
For you, your price will most licky be around 100.
Dont get me wrong- most homes actually do not have an RO built in- its usually homes that have a home builder's diagram and request to have one put in place.
RO systems are nothing new and are used by busnesses and all pet stores. They have hit the house market hard and can now be place on your tap nossel
look into it..
The Ro/DI is a Di-ionizer-best for reefs..
