Hi guys

How do you calculate gallons per hour.


Thx Guys:>



1) 55 gallon tank
2) 1 Marienland 55 gallon canister filter 220 gallons per hour
3) 1 aquaclear 50 filter ( Pollywhool inside) This is just to help polish the water and circulate oxygen in the water.

Thanks:)

Not entirely sure what you are asking. The correspondence that comes with commercially available filters will more money give you all this information. They will tell you what tank the actual filter is suitable for. Obviously this is very important information as using a filter that is only suitable for 30 gallons on a 100 gallon tank could cause problems with the water. Even if you only buy a powerhead, they will tell you how many gallons an hour it would shift so as long as you know how much water is in the tank, it's easy to work out. Please correct me if I'm wrong, but I don't think you need to be a mathematician to work out these things.

i guess it is that simpleB) lol i was just confused because im not sure what these filters are actaully rated at beacuse the aquaclaer is rated at 200 gallons per hour but it sure doesnt do that good of a job in conparison to my canister filter lol.

Thx For you time

The flow rate of any filter will be governed by the type and amount of filter media and bacteria you have in it. the flow rates that are given by manufacturers are the pump rate and are probably not measured with filter media in them. You will notice over time that the flow rate will decrease ads the filter becomes clogged by the build up of detritus. You should aim for a flow rate that turns over the total gallonage of water at least once per hour. I.e. if you have a tank of 55 gallons then you need a minimum of 55 gallons per hour turnover.An easy way to measure your flow rate is to put the outlet pipe into a measured container and run it for 1 minute. Multiply the amount of water you have collected by 60 to get the gallons per hour.I wouldn't mind betting that its nowhere near the claims made by the manufacturers

Steve definitely mentioned something that needs to be watched. The longer you leave your filter, the dirtier it will become inside, this is especially true with sponge media. Sponge does have a habit of getting clogged up very quickly if you have large messy fish. When this happens, the flow rate can be seriously restricted. When this happens, the water isn't being claimed as quickly. You can also get rapid bacteria break down if the water isn't passing through the media properly. This is why I always recommend more filtration than you actually need when keeping Oscars.
