I missed that. Now I´m convinced that it most be a problem with your RODI because the TRITON test shows figures of different compounds that you can expect from a well where your household have the water cleaning equipment you have. My experiences with different local wells here in Sweden say that.
Does your daughters’ freshwater aquaria take water from the household or your shop?
Yes her tanks are in the house and after the Kinetico water softener and Iron filter.
Do not take this question as an insult (I have personally done more idiotical things than this) - you have not - by mistake - take your aquarium water from the waste drain of the RODI filter?
Not an insult at all, I also have experience with things like this.
That said yes I am collecting water from the output of the RO/DI.
I have a 3 input TDS meter,
Sensor 1 located between the RO and DI stages and reads 80-150 and drops to 5 after the bypass rinse.
Sensor 2 is between the Cation and Anion stages, and reads from 0 - 45. (Was told by BRS this is normal)
Sensor 3 is on the output side and is always 0
My RO/DI unit is set up as follows.
Source water into:
Particulate filter to
5 micron Carbon canister to
1 micron Carbon canister to
RO membrane 1 to
RO membrane 2 to
Cation canister to
Anion canister to
Mixed bed canister to
Storage container.
Containers are NSF containers.
By the way - your Hanna checker can´t read this low concentration of iron - Hanna themselves say
- Accuracy ±0.04 mg/L (ppm)
Triton result 12 ppt is the same as 0.012 ppm - well below the accuracy - trust TRITON
Will do
Do a iron test direct from the well - before your RODI equipment. If reading anything - do a test both from the waste and clean water from the RODI unit. Take a test from your tap in your household too - after all treatment equipment.
I will have to order more Iron reagent packets as I only have one left.
