Salifert Nitrate test

[GillMeister]

Yea, I’ve read quite a few forums stating I need to invest in my own RODI system. I’m looking into options. I’ve only had the tank 6 months.

You don't have to spend a fortune on a good RODI system and they provide some peace of mind, as well as saving money in the long run. Just make sure you get one that has the capacity you need so you don't have to wait for days to get your mixing bin filled.

At least you seem to have found the source of your problem, and you helped make the case for a lot of people that haven't purchased a RODI filter.
