Stage 4 – When should I change the Reverse Osmosis Membrane?

The R.O. Membrane is the very heart of your Aquasafe Reverse Osmosis System. The R.O. Membrane

is rated for an average of 4000-5000 Gallons of purified water production. If you have a TDS Meter a

very simple but critical test you can perform in order to determine if your R.O. Membrane needs to be

replaced is to measure the PPM reduction rate of the purified (permeate) water coming directly out of

the R.O. Membrane housing (see Fig. 29 and 30 for how to do this).

Testing to see if your R.O. Membrane needs replacing.

Step 1. How to depressurize your system (Fig 29)

The PPM count should be 15% or less from that of your unfiltered tap water that can be gathered from

any cold water tap in your home.

•

Example: if your unfiltered tap water is 200ppm then the purified permeate water coming out of

the R.O. Membrane should be 30ppm or less (200 x 0.15).

If your R.O. Membrane is not producing the 85% or better in PPM reduction as depicted above, you

need to change this membrane.

Are you unsure when you last replaced your R.O. Membrane?

Because the weekly gallon demand varies greatly from one aquarium enthusiast to the next, we

highly recommend that you test your water immediately as described above to see if your mem-

brane is still producing an 85% ppm reduction from your normal tap water (based on the permeate

water test in Fig 30). If you don't have a TDS meter to do this with, get one right away. The health

of your aquarium depends on it. If you can't verify the ppm of your water you can't guarantee that

your aquarium isn't being exposed to harmful contaminants.

Stage 5, 6 & 7 – When should I change the resin in the D.I. Resin Canisters?

The D.I. Resin Beads inside the D.I. Resin Canister typically need to be changed along with your pre-

filter changes. However this is not always the case. The D.I. Resin is "color-indicating" – meaning it

changes color to signify when the resin has become exhausted and needs to be changed. The color-

indicating resin will change from emerald green to amber-orange or brown when exhausted. All

Aquasafe D.I. canisters are 100% reusable by way of the removable blue end caps.

It can be misleading when trying to observe the color of the resin when the canister is filled

with water as the water gives a darkening effect. To observe the true color of the resin it is best to

hold a flashlight to the canister to illuminate the true color of the resin. Alternatively, disconnect

the tubing from one side of the D.I. Canister to allow a portion of water to drain from the canister

revealing the true color of the resin. Please remember to depressurize your system (see Fig. 29)

before disconnecting tubing from any point on your system.

Stage 8 – When should I change the Final Polishing Filter?

This is the final filtration stage in your R.O. System. The Final Polishing filter is rated for 1800-2000

gallons of purified water production and therefore should be changed every second time you change

your three pre-filters.
