Filteration In The Pond

[Dude]

my question is ,if you didnt get it from the title , do you have to have filteration in a pond

i will be making a pond soon and i really dont have the money to buy a great big filter

will it be ok if i just grew alot of plants and had (like in betta bowls) bactiria living in the gravel?

i will house a maximum of 5 goldfish ... commet probably... as far as temp the weather is stable not too cold

it never even gets close to snowing .

my pond will be about 100 -200 gallons

Its always a good idea to filter a pond. Ive no idea though of the size of pump and filter you will need so will leave that to others. I have roughly an 800 gallon pond thats 4 foot at the deepest *essential for over wintering any fish in the uk* and it has a 5000ltr pump going into a 9000 ltr filter.

Your best bet is to make the pond now while its still warm enough to do so and then fill and leave it until the spring before adding fish as its really too late for fish now.

The pond is quite a small one, so i would strongly advise getting filtration for it- it will improve the quality of living for your goldfish by miles, as well as improve their life expectancy and health too .

As black angel has said though, its too late to add indoors fish to ponds, its ok if you are getting fish which have already live outdoors, but the temps in the pond will be too cold now to acclimatise indoor fish to outdoor ponds.

yea i know but would it be ok if i didnt get a filter

will they be able to live

ofcoarse i will be doing 20% water changes every week like a fish tank/

I see you are from Israel, what kind of climate do you get year round?

Ammonia will eventually build up even with 20% water changes on a regular basis, as each time you will only be taking 20% of the ammonia out so unless you do 100% water changes on a weekly basis, the goldfish will evntually be poisened to death by ammonia levels building up in the pond.

It would also be overstocked without the filtration with 5 goldfish- 5 comet golfish are only advised for such small ponds if they have filtration.
I remember a long time ago, my grandmother got some goldfish for a pond of similar gallons with no filtration and they all died within 1 year of being in the pond (cause of death= pond too shallow, ammonia levels built up, continueing suffocating algae problems killing the fish one by one- there were none left by spring the next year).

Also, how deep is the pond going to be? If you live in a cooler climate like in England, it will need to be at least 3-4ft deep to give sufficient protection against freezing for the fish so they can hibernate properly throughout the winter .

yes i do ...in the area that i live in we get hot summers and the winters dont get any colder than 15 c

but weather is very stable here no suprises...

ok then i dont want that to happen

could you recommend a filter something not to expensive

it will be like a well but it will be about 3 feet deep

the number of gallons is just an estemate im sure its like arround 100 galls

Unfortunately i cannot advise any particular makes of filters. But generally speaking, you need to figure out the exact amount of gallons (wether US or UK gallons) and then shop for your filter from there onwards- the filter should be able to filter more than your ponds gallons, so it does not struggle to do its job at all .
