I'm using your Ocean Reef +1

when should I replace my filter? I think I got alot of water out of it

According to the TDS meter that it came with the unit

in = 126 ppm

out = 0ppm

Sediment and carbon filters should be changed once every six months and DI as needed. DI resin should always produce zero tds and changed at a reading of no higher then 2-3 and RO membranes generally last 2-3 years. Color change in DI resin is only a heads up to exhaustion and will run from the bottom up to the top. A DI cartridge can totally change color and produce zero tds but exhaustion is near and it may turn black at the bottom again.

The tds meter only reads total disolved solids and is no indication of the condition of the first three filter stages.
