I was wondering if any of you have attempted to use one of these http://www.campmor.com/outdoor/gear/Product___69478 to purify your loop? It seems like it would work, just dip it in your res every couple of weeks.
There totally isn't anything wrong with the normal forms of keeping the loop clean, I was redoing my loop and just thought of this as an alternative to using a coil or biocide. But on another note II want to know if there is any product out there that will prevent clouding in clear tubing?
If you use these UV sterilizers make sure you do not expose your own skin to the rads 'cause the device can cause serious UV skin damage within seconds.
