Anyone have experience using Cold Tub UV Sterilizer
or other non aquarium related UV lights?

I'm playing around with a 400 G no water change tank, I've been able to keep the nitrates down for the last 6 weeks, but likely need some sort of sanitizer as it appears some random bacteria stuff is growing (I changed water and it seemed to work). I understand there are other parameters, but I'd like to get to a place where I limit my water changes, instead of constantly changing water... At least try to.

Any input would be greatly appreciated!
