I have a 200g reef tank. Been running the RO/DI for 1 year with the original filters; unit is configured for 90GPD.
Tap water is fairly low TDS at 60-80ppm.
I'll typically get between 53psi-58psi pressure.
1 year of RO/DI product water = about 1800g between WC's, ATO and QT tanks.
Took some measurements today and trying to determine if it's time to replace any filters.
1) Waste water : product water @ 53psi = 2.5:1
2) Measured TDS Output vs Input = 47:0
3) RODI product water calculated at 2.74GPH/65.76GPD
4) 0 chlorine tested at waste water (see test strip)
