I'm currently using Nova Aqua + and Amquel + but as soon as these gallon jugs are empty, I'm going to give Prime a shot too
Another Prime user here.
Prime. I have heavy metals in my well water.
I have been only using Stress coat so far. Since seeing this thread, I gonna give prime a try after my stresss coat bottle runs out.
I switched to Prime a couple of years ago and have been very happy with the results!
I have been using prime since my TSS cycle failed (but not completely). However 3 weeks later I had zero ammonia before my WC this morning. Since I have a huge bottle of API water conditioner and no ammonia in the tap I used that instead so I can check again before 24 hours.
