So i just purchased a 90 gal tank that will be a reefer. Pretty straight forward question, do i need a 5 or 6 stage filter? here are the results from this years water test.

I had a 4 stage and was still getting TDS around 5ppm.
I upgraded to a 6 stage and can make several hundred gallons at 0ppm TDS before filters need changed.
Buy a 12 dollar TDS meter and experiment with it, that is what I did.
This i did not know. Man im so grateful for this forum i learn something new every hourYou can always add on to the RODI as needed. I started with a 5 and moved to a 7 due to high levels of chloramines and silica in my area.
