@callum@psi i bought one of these units
http://www.psifilters.com.au/revers...stems/aquarium-reverse-osmosis-units/PSI-020A
and now i see that you have a reef di systems here http://www.psifilters.com.au/revers...mount-reverse-osmosis-systems/di-reef-systems
but it does not list the one i purchased. does that mean the one i have is not good enough for a reef system? also where on your website is the replacement filters for one i purchased? im after some replacement filters for the whole unit.
thank you
