External Filters And Real World Throughput

[fish+peace]

After upgrading my tank from a 97litre to 180litre i find my filter not as efficent though still adequate - the filter is a fluval 206 with an adevertised throughput of 780lph supporting upto 200l


whilst i'm aware these are likely done in ideal conditions ie no uphill pumping and no media inside to provide resistance, the filter market is no exception to this concept - car mpg's for example.

I was looking at upgrading to get nearer the 10x optimal refresh rate per hour and note the fluval 406 new coming in at around £140 and APS to be had for around £50 boasting of 1000+ lph

does anybody have any real world results of actual realistic throughput - i've read that the aps is woefully optimistic

what are your views? is one manufacturer closer than another to the claimed throughput?

All filters are tested without media so results differ from person to another. It honestly depends what you have in it that will improve/decrease flow. Same with cars mpg, there tested indoors on a rolling road, nothing outside is taken into account therefore suggesting your car could do the mpg if conditions were prefect.

I use MA filters, 1000U and it says it has 1000lph and I could believe it. Really good flow and solid filter I use it on my 200l

There is a thread on here somewhere where members have tested their filters flow true output.

I have had a seach but I cant find it but it contained some interesting information, hopefully someone will be able to find it for us.

Even an APS2000EF would not throw your fish around as if they were in a washing machine, mine do ~1200lph with no spraybar modules attached. With spraybars, the output drops to a pitiful ~800lph! I have two of these currently on my 48x17x22 (~280l) with a Biopro 2200 mechanical filter/powerhead, which contains fish <5cm that enjoy moderate current.

My Rio240 on the other hand has rheophilic occupants, that have a Fluval FX5 (~2300lph); Eheim 2078 (~1100lph); Biopro 2200 mechanicla filter/powerhead (~2000lph).

what you have should be more than enough, what exactly is the problem? is your water not testing good? not really sure why everybody seems to want excessive amounts of filters that are not nessessary....over filtration does not improve anything, its just a waste of money and electricity....most of the time maintainance is the problem....not the filter.....

I think your probably right, suppose its human nature to want bigger, better and more - its the same with any hobby really think they call it 'gas' or gear aquisition syndrome' i think the only time its really noticable is when you do a clean out and it takes alot longer for the water to clean up as oppose to when you have an overkill filter.

Thanks for the link that was what i was looking for - if i was to sum it up in a nutshell, Expect half of stated
claims.
