Just Got A Free Bath Tub For A Pond

[Gurglar]

So I just picked up a free bath tub so I can make into an outdoor pond from a quick measure I did it will be able to hold about 65-70 gallons and I plan on putting 2 fancy goldfish in there and thats it.

Now how do I go about filtration I haven't looked to much into outdoor filtration so have no idea what to get and what to looks for so all help is appreciated??

I've seen stingrays but they are only pumps aren't they not an actual filter?

what else do I need to keep my pond healthy and clean?

You might try buying a pond fountain pump, with a filter on the inlet to help keep debris out of the pump. It is what I have used in my tub pond the last 2 summers and it worked out great. This is the tub with the filter / fountain running on it. The filter is just a typical sponge filter that is designed to fit the fountain pump inlet tube.

I read about a pond filter in a book, and thought about downsizing it. Basically the outlet of a water pump goes into a container with media, and a pipe in the bottom-side of the container. But the pipe went on the inside bottom of the container, then turns up like a T joint. you have to cut the media accordingly. There are many holes in the bottom pipe, and on overflow on top. Like a big backwards capital L with holes in the bottom of the L, and the top of the L is just open.

Hope I explained it well. Tell me if I didnt...

I'm wondering if I could just use a normal cannister filter cause thats all the pond filters are that i've looked at but they have a UV light in them for algae and have alot more flow compared to normal cannisters but since my pond is only a 70 gallon I could probably get away with the flow rate or a normal cannister.

Now how beneficial is the UV light in the filter will it actually stop algae or just stop the water going green and algae will still grow on the actual walls of the pond?

Also looked at the aqua one stingrays (there just a pump) that we sell at work and the smallest one was a 4000 litre an hour ones and costs $390 but with my discount I get it for $147 massive hey!

Another question if I just use a filter and hooked it up to a fountain would it still work as good or would it just trickle out and not do much?

I just don't wanna run a filter and then a pump for the fountain aswell, which then leaves oldmans idea or I try and build my own filter out of a container and hook the pump up to that then to the fountain.

That "idea" of mine is a standard setup from a fountain manufacturer. It is a 600 gallon per hour pump that sits on the bottom of the tub and comes standard with a sponge filter on the inlet. I bought a T adapter and put 2 sponges on the inlet instead.

Well I ended up finding one lonely pond filter we had sitting at work with a UV light in it and bought that for less than half price and my mate just gave me a 2000lph pump so i'm hoping that will be enough, the filters rated at 3000lph.

It sounds like you are set. A bathtub is probably not going to hold more than about 200 to 300 litres of water so a 2000 lph pump will be more than enough and the larger filter gives you a safety margin when it comes to the UV effectiveness. My 150 gallon stock tank is bigger than several standard bathtubs put together.

Thanks mate this tub holds about 250litres so the filter will be more than enough I just didn't know if it was suitable to run a smaller pump on a filter made for larger pumps.

Also in the manual it says to use the biggest possible hosing (the connection can take small to huge hosing) but this only has some small hosing on it which fit snuggly onto the first notch of the connection which is the smallest, so would I be alright running that hosing or should I try get something bigger??
