RO Parameters

What parameters are we looking for when testing our RO water? My chlorine test indicator is clear, or zero.

Is this super clean water ready for use in my tank?

Or are there other tests I need to take?

The chlorine should be removed by the carbon filters before it gets to the RO.

We test for Total Dissolved Solids. We like to see zero TDS after RO and DI.


Current Tank Info: 125 in-wall , 40b sump. 6 bulb T5. ASM G2 skimmer. LPS and leathers

I agree that a TDS meter would be the single most useful way to check RO/DI water quality.
