Fully submersible pond UV light and biofilter.

Mr. Peter May;

Thanks for responding so quickly. I'm reasonability new at all this fish pond stuff, however, I definitely love my pond and I'm now looking for methods to improve it. Unfortunately, I already built the pond and am stuck with making improvements based on the existing physical structure. I would like to know if you have any suggestions for a fully submersible UV light and biofilter.

Thanks Again for your Guidance,

Best Regards,

Kirk Callais

Hi Kirk,

I'm not aware of a submergible UV light and Bio filter set-up, certainly not available in the UK. If you are looking for something small and easy to hide there are several manufacturers making a Bioforce biological filter that is a miniature biological filter that works under pressure from the force of water straight from a submersible pump. You can get these with integral UV lamps to suit ponds and pools up to 2000gallons (9000litres). Their main advantages over the conventional systems are that they are a small -maximum size 18inches by 14. They can be dug into any point from water level to the height of a waterfall. They can work in conjunction with a normal bio filter.And they are easy to clean by just back-flushing. Hozelock, Oase and Blagdon, Interpet do these in the UK and the are brilliant. You need a pump capable of delivering water a fair pressure.

There are submersible filters also in the UK but they tend not to work biologically and since they tend to be fairly small they need regularly cleaning out.

One of the best filter systems available works in the pond and that is the 'spider filtration system' that works by having a pump sitting in a large bed of pea gravel supplying either a waterfall or fountain. The inlet to the pump is adapted to take several long tubes perforated with holes and these allow the pump to suck water from across the whole filter bed of pea gravel. Bacteria build up in the gravel and digest the organic debris and process the organic compounds dissolved in the water as it gets sucked down. The filter bed theoretically never needs to be cleaned out, but you have to be pretty diligent about not letting leaves fall in, over feeding the fish and not having too many of the darn things.

Hope this helps.
