I want to change my my filters in my RO
unit. I bought the pack for 4 stage unit which is what I have. It came and one filter is not the same and although It would fit I am not sure if it does the same thing.
Old filter is a resin filter
New filter is post carbon filter
If I put on the new filter and remove the old how will this affect my water quality?
I use the water in my 3 salt water tanks once mixed with salt and also use the fresh in my two tropical tanks.
Picture is of the unit before filter change.
Thans in advance fot the advice.
