The first thing they do is look for others sources that could have caused a issue with there products before actually looking into there products. I’m sorry they check to see if it’s under warranty first.I am simply saying Neptune could deny any help and say the third party reagents caused the issue. They would likely sell you the parts still. Doesn't matter if the chemicals are the same though. Neptune can immediately blame something else and they likely will. There will be plenty of people who get these reagents while still under warranty.
I have no dog in the fight. I don't have a Trident and have zero plans to get one.
