Could someone give me a general idea of how many gallons/litres this pond holds, I’m looking to buy a new filter, I have no idea about ponds but the previous owner of the house had a (up to) 9000 litre pond filter, do I need one that big When looking for a replacement ?

thanks

The only way to estimate pond size is with measurements - width, length and depth. There are online pond calculators that you can just plug the numbers in and you'll be close.

The only SURE way to know is to put a meter on your hose and fill the pond from dry.

In case you didn’t know Lisa you can also get volume using salinity and stoichiometry. Take an initial sample, measure the salinity, add a known amount of salt, let it diffuse and measure the salinity again, and then with some math you can calculate the volume. I think I heard it from the pond digger.

Well, that would indeed seem like a possibility. But what if I don't have salt in my pond to begin with?

I would not use salt levels to find pond volume. Salt is not necessary and the only way to remove it is water changes. You can use one of the online sites or just use length x width x depth x 7.5.

I believe you can never have too much filtration.
I would opt for larger than you need.
Remember, your fish constantly grow and will multiply, possibly causing an overcrowded condition. Your filter can quickly become inadequate with all that fish waste, so the larger the filter, the better.

Get an estimate of your volume and post it up here so we can help you out.

Another way is to time how long it takes to fill a 5 gallon pail. Then starting with an empty pond time how long it takes to fill the pond. Then do the math.

If the initial test has a 0% salinity all the better, makes the math easier I think, but usually water will have at least some dissolved sodium in it, which is why you need to do the initial test. I found these official instructions: https://russellwatergardens.com/pages/water-volume

I use a thing called a "water saver". It's a small digital meter that screws onto your garden hose. I've had it for several years and it was under $20 on Amazon.
It comes in handy when using a dechlorinator/conditioner too.

I just wait for my husband to yell about the water bill! He tells me EXACTLY how much water I put in the pond!
heh; that's what's soooooooo nice about having a well--no water bill! Still, you need to give the hub something to do, don'tcha? :)
