Besides killing algae, what do you use a UV sterilizer for?

Can it be used to control potential diseases by killing bacteria or parasites? Then, I'd be interested in a Turbo-Twist. Otherwise, I guess I better get a diatom filter.

Yes, it will kill free floating bacteria and parasites given enough dwell time. IMO, diatom filters and UV sterilizers have different functions. Diatoms are good for polishing water and do a great job at cleaning up green water quickly and, in my experience, also made quick work of GDA when used with frequent water changes. UV sterilizers can also clear up green water, but of course neither address the cause of algae, just the symptoms. UV sterilizers kill harmful bacteria and parasites in the water column effectively.

UV sucks!

does the UV kill anything useful in the tank?

My understanding is because beneficial bacteria don't free float, the UV doesn't kill them.

My tank water looks like liquid air thanks to Purigen and 50 micron pads. So, I don't really need water polishing capabilities of a diatom filter. If the UV truly sanitizes my tank water, I'd be very interested. A 9W JBJ submersible UV is only around $70 and it's tempting...

That's a lot of useful info.

Here's some info on how to pick the correct size based on flow rates and your needs.

UVs can help with certain parasites that have a free-swiming stage in their lifecycle. But they can also kill useful organisms, such as infusoria that fry feed on.

Many people use them on their tanks. They can definitely help to prevent green water and unsightly bacteria blooms.

Personally, I don't care for them b/c I like the idea of infusoria thriving in my tank water.
