Pond Uv For My Aquarium

[Fishy_7]

I am in the process of stipping out and filling in a pond at my mum's place. There is a UV lamp unit - Hozleock Vorton 9000 and I am thinking of attaching it to my 212 litre aquarium set-up. The bulb is 11W, does anyone see any problems with this. It is a little overkill but as the unit is just there - seems worth having a go.

UV mainly is to eradicate green water (suspended algae) which is a common issue in ponds due to the variance of natural sunlight. It will kill some diseases which are free floating in the water however the benefits of this in a home enthusiast set up is negligible as the fish become use to the lower disease levels their immunity deteriorates and they may become more prone to illness.

pond uv clarifiers are designed to clear ponds of water born algae. Uv sterilizers are designed for removing algae and bacteria and other naughties from aquariums, (and ponds i think?)

Meaning that in general UVs have little efect in aquariums? In order, does water go the UV before filter or filter than UV? Thanks.

Uv then filter with quite a lot of filter floss to catch the dead particles

Filter then UV unless you want to clog your UV and have to clean it out.

One thing that I can see that won't work is that it probably has a 3/4" hose attachments.

That wouldn't occur very rapidly in an aquarium setting and you want the filter to catch all the dead stuff it just killed.

That is a very good theory except you forgot about one part. It takes around 5000-10000 micro particles to clump together for filter material to catch it. The only way it can do this is to be sent back into the tank/pond and circulated. Dead micro particles of algae are no bigger than the living ones, and your filter does not catch the living ones.

Everything I have ever read about pond keeping/uv sterilizers tells you to go filter then UV.

In fact I have never heard of anyone going UV then filter. In some models, like mine, the inside is ridiculously hard to clean and if that gets jammed up with poo and other aquarium waste it is going to be a pain in the butt to clean.

Positioning the UV Unit
Vecton units have two handy key hole slots in the back plate, which may be used to
mount the unit on a vertical surface, they also come with four sturdy rubber feet which
allow the unit to be placed in a horizontal position next to, or near, the aquarium.
The exact positioning of the Vecton unit is not critical; the main requirement is that the
unit can be reached by a supply of aquarium water, pumped through flexible hose and
returned to the aquarium or sump via flexible hose. A dedicated pump may be used to
supply water to the Vecton unit, or the return flow of water from a power filter may be
used. It is advisable that water pumped to the Vecton unit is pre-filtered to remove any
dirt particles, this ensures maximum UVC penetration through the water.

this is from the tmc vecton user manual

It is highly unlikely to have free floating algae in a internal home aquarium so wouldn't it be preferable to kill the bacteria living on the deitrus and other matter before it rots by being caught in the filter sponges. However to contradict my own point this matter would likely to have just renewed bacteria colonies growing and rotting the matter anyway so you would just be delaying the inevitable but this delay may provide you a time of little rotting inbetween filter cleans. I think you could go either way on the issue.
