Greetings,
I have a 7 stage RODI system that is producing water with ammonia. I have multiple questions, but first let me give you what I know. The system is new, I had one already in place but was getting ammonia readouts in the water. I bought the old system (6 stage 150 GPD) used, so I decided to get a new one in case there were issues. I have a large tank so I needed more water any ways. I upgraded to the 7 stage 200 GPD system from BRS. Pressure gauge reads 53 PSI, while the ammonia reading I am getting is currently 0.09. I ran the water out of the blue line (not going through the resin yet) for 1 hour and 30 minutes. I then ran it through the entire system (DI part as well) for about the same time and got a reading of ammonia at 0.11. I then ran it through the entire system for about 7 hours (I slept) and then got the current reading of 0.09 ammonia. My checker that I use to test for ammonia is the Hanna Checker. The checker is good, as I bought a calibration test kit to test it and it is dead on. The anion is the only thing that is depleting at the moment. The cation and the mixed resin look completely good still, while the 2nd stage of the DI (anion) looks to be almost, not quite a 1/4 depleted. My TDS reading is 0 after the 2nd stage of the DI. Unfortunately my city won't produce a water report until July 2023, and the current report they have posted is from last year. I have been trying to cycle this 170 gallon tank (225 system with sump), for a while, and it turned out I was possibly always adding ammonia.
Questions:
Is this level of ammonia bad? I understand certain variations of ammonia are more toxic than what the fish produce, is that this version of toxic ammonia coming from the RODI?
Is there something I need to add to my RODI setup?
Is there something else I need to test?
Will my tank adjust itself eventually since I have been adding this RODI water in there with ammonia or will I need to do a big water change and essentially start the cycle over?
