Pond canister filters and pumps

  • We are currently upgrading MFK. thanks! -neo
does any pond water pump work? or do i need a specific kind with the right measurements?
 
thats the pond filter i want, but i dont want to buy them wrong kind of pump for it, if it doesn't fit the filter or something
 
You can not just use any pump. The filter is rated for a certain flow rate so if u use a pump that’s greater than that flow rate you can easily blow the seal on the filter. It’s a pressurized filter so pumping under the rating fine but pumping over can result to damage to filter . Blowing the seal will be a flood and possible drain of the pond if u are not careful.
 
assuming the flow rate is correct, what kind of pump do i need otherwise?
i dont want to get the wrong kind of pump, such as one with different sized fittings and it not be able to connect to the canister filter nozzles or something
 
That model says max flow rate of 9000 gph so pick a inline pump of your liking with that spec,
. Make sure u account for head pressure as well.

If you buy a pond pump rated larger than 9000 gph you can always put a t piece and diverter valve on the pipe work to send some of the water straight back to the pond and some through the filter. This also helps when cleaning the filter as all the water can be diverted to go straight back to the pond whilst you clean the filter (unplugging the uv first of course).
Most pond pumps come with variable sized adapters to fit different sized pipe work so you should have no trouble matching the pipe work of the filter and hence that hose size to a decent pond pump. Only when you do connect it, first cut off any smaller connections as this will restrict water flow.
Always use the biggest fitting on the filter and pump and hence the biggest pipe you can as this allows better flow and doesn’t restrict the rating of the pump.
Note however that you need to rate the filter and the pump to the pond you have or will be making and the stocking level you have/ want. So if you have a 5000 g pond then a 9000g filter would be fine but if you had it heavily stocked with koi then you would need a bigger filter and hence bigger pump.
Note that you also need to take loss into consideration when rating the pump. If it has to pump up to the top of a waterfall then the flow rate will be greatly reduced. So a 9000g pump may only be pumping 4000g for example at the top of the waterfall where you have your filter, so you could have bought a bigger pump! The pumps should come with a chart showing flow rate at water height (so how high you need to pump above the level of the pond) to help you chose the right one.

That filter is rated up to 9000gph and can filter up to 16000g pond.
My question is how big of a pond are you building?
If your pond is smaller then 16000g you don't need to max that filter out. That filter will work at lower gph if your pond is smaller. Also depends on what you are keeping in said pond. Alot of typical pond fish don't like huge amounts of flow.
