i have used them on my tanks and even on my pond.
Although I hav eremoved them from most of my setups, I see a difference with them.
The algae is slowed down.
It is also supposed to controll parasites.
The one mistake most make with uv's is the water flowing too fast
check manuf. instructions, but uv's need to flow slowly. to ensure enough contact time.
