My loop has been running over a year with distilled + Primoflex LRT and the water in my res is still clear (and so is my res for that matter).

It works as advertised. Every extra thing you add to your loop is just asking for trouble.

how do you know this for sure?

i have the same tubing and yes you are right about everything being clear but i just thought it was the use of distilled water, i also have silver in my loop...

thanks for the info!
