Unfiltered Tub pond
I was thinking about making a pond out of a plastic storage container like this . .
Its huge and about 50 Gal . . .
Just want to put in some fancy guppies.
Can I have them in this tub outdoors? This wont be filtered but I plan to change 20% of water daily.
I'm also planning on getting some pond plants. Maybe have some hornwort in there as well.
Where I live is pretty hot almost everyday. We do get some nice rain but its still hot. So temperature isn't a problem.
Do you think it's a good idea?
I was just going to ask about this. I have a tub pond already in my yard for years now, never put anything in it, just full of water and rocks. I was looking at a couple different things of people saying they just put fish like guppies and bettas in without any care and they took them in at winter with tons of fry and the original fish all large, so I figure it should work. Mine is about 50gallons too, just wondering what types of plants to put in it. I was thinking of putting a lot of the java fern baby plants growing on the leaves in my aquarium in there, but would need more. Also it tends to turn completely green all the time, what could I do to control algae?
Some local people in my fish club do this in the summer. They use 50 to 300gal bins and cattle troughs for fish. Some do no filter, no heater, no water changes all summer. Usually the tub is seeded from a pond in early spring, and dirt/much is added to the bottom. Live plants can be added too. It is allowed to go green, basically one big green water culture. Then daphnia is added to the bin, once they have reached a decent population. Fish are added, usually this is for egg laying fish. Young and adults can often live and breed in this tub for some time feeding off of all the microorganisms. Livebears, probably don't need so much prep, especially if you plan to feed them. A number of people recommend a fountain to provide some circulation and aeration of water.
With no water changes, most install overflows, which are just holes cut in side of bin where you want the water level to be. Then screen is fitted over the holes, this stops bin from overflowing when it rains. It can rain quite a bit in MN/WI, if you live in a more arid climate this may not work.
If we can do it while being neighbors to Canada you shouldn't have a problem:-).
My unfiltered tub pond project
I was surprised to see your post. I'm making a tub unfiltered pond also for my yard. I'm going to put a small bubbler fountain in the middle. The plants will be Hornwort/Anacharis that you can pick up at any pet store. These plants are best to filter the water without a filter. Hornwort & Anacharis sucks out fish wastes faster than fish can excrete them. Carbon dioxide, Ammonia,Nitrites, Nitrates and Phosphates all go into the fast-growing foliage. They are also one of the top oxygenating plants to have in a aquarium or pond. Anacharis you can get at Petco for about $2.99 a bunch.
I checked craigslist in my area and this guy has water hyacinths and Mosquito fish that I might pick up.
I checked Homedepot and they now have Waterlily bulbs for $9.98 comes in white,yellow, or red flowers. In the Tropical Fish Hobbyist magazine April 2008 issue under The Planted Tank section they have a big article on Vegetative filters for your water garden or fish tub. They listed these plants:
Hornwort- very good plant for filtering water
Anacharis-very good plant for filtering water
Water Hyacinths- This is the best vegetative filter for a pond or tub
Fish list that are good for small tub ponds:
small gold fish- small tub only 1-2
I plan on putting pea gravel on the bottom. I bought 3 bags for $3.50 ea at Walmart
I bought the big rustic looking tub at Walmart for $25
The fountain pump was about $25 at Homedepot
I have not put it together yet but plan on taking photos of my project and putting it on youtube.
Here are 2 pictures of the Tub + supplies I got so far.
I was thinking about the same thing...
The only reason I don't really want to use guppies is the fact that from above, they're quite dull. Might as well have bait minnows in it...
The daphnia/Green water is a good idea... will keep the water clear I suppose... (If the fish don't eat all of them.)
The only thing I really wanted to say, is I think Vallis are good oxygenators too... and would give a great cover for daphnia to make sure they weren't all eaten.
(I was just gonna make my "pond" in a rectangular rubber-maid bin. The pot looks much nicer.)
Thanks, I saw this bright yellow poly resin pot at Walmart and did not like the bright yellow color and in the garden dept. on the high shelf I found this rustic poly resin pot it's plastic and does not have a hole in it so it is perfect. It sure looks better then a bucket. I almost was going to settle for a bucket with the handles also. I did not think of putting Vallisneria in it. I have some of this in my 55 gal. tank. It grows like a weed like kelp. The other plants I mentioned are better for water clarity and filtering without a filter. Once my water hyacinths or waterlily bloom it will shade the pot so the water should not get to green. I guess you can use a UV sterilizer if you want clear water. I would think that the algae would be good for any fish you put in as it would be self contained eco-environment with out a filter.
Just a few ideas judging from my in-ground pond here I'd not sit it in a spot that gets direct sunlight 24/7 but maybe only morning sunlight. Rainwater will do the trick for you for water exchanges, if you have extra plants maybe from a tank of yours toss some in (Pennywort works great for that)...then the only last advise I'd have make sure you have no dog on the property like mine who WILL go and regard it as the most fancy water bowl he's ever had and try to drink-snatch a fish, drink-snatch a fish....otherwise add a screen cover over it :-)
Thanks for the advice. My tub is 19"H x 24"W. I have a dog but it is a Miniture Pinscher and is only about 13" tall so I do not need to worry about her using it as a water bowl. I suppose that it can pose as a hazzard if you have small children as they can fall inside the pond.
Updated: Unfiltered tub pond pics
Here are some more pictures of how my pond came out.
The first picture is of some of the supplies I needed. I have Silicone Aquarium safe seal for the clear tubing I had to put in the back for drainage in case of rain water over filling the tub so it will drain. I drilled a hole above the water line and then siliconed the tubing in place in the back. I then used tie wraps to secure the plant basket in back. I drilled 2 holes on each side of the basket and 2 holes on the tub pot. I then used tie wraps to secure the basket. I used a plastic plant pot for a stand for the pump.
The back of the tub where the drain tubing went and the basket got secured to the back with the water Iris, I put gravel on the top of the pot.
The plastic pot stand for the water fountain to sit on
The empty pot with 2 bags of gravel on the bottom with the fountain pump in the center.
3 pictures of the tub pond with water in it. I put a Water Hyacinth in the pond instead of the waterlily. I got the Water Hyacinth at a garden shop for $2.99. The guy at the garden shop gave me some duckweed for free to float in the pond. I also go 2 pond platies that they had in their outside pond for free. I gave them my 2 Mosquito fish for their pond as I liked the Pond Platies better. I also put some Hornwort from my aquarium in the pond.
The Pond Platies that I put in the tub pond. They are a nice yellow color and 1 is pregnate.l
