How Much Is Too Much Filtration?

[dave_oddballs]

nearly 285 gallons. the fx5 does far, far more filtration than the eheims, they don't even compare to the amount of water that the fx5 does, i have them sat side by side all pretty newly set up so no clogging of either, so no one can tell me that the eheim filters more water than the fx5, the amount of filtration that the fx5 does, or more the quality of it is not far different from he eheims.
the thing that push's people more towards eheims is the quality if im correct. if i had to have one of the filters either the eheim pro3 2080's or one of the fx5's it would be the fluval, i dont think id even have to put much thought into it.
i just wanted to know peoples thoughts on the turnover and the amount of filtration on the tank, not really the arguments of which filter is better, i would of had a sump but drilling the tank is more bother than its worth and in my opinion id need to have about 4 sump pumps to move as much water in the tank as these 3 filters do, and considering the 2 eheim pr03 2080's cost me next to nothing and i swapped the fx5 for some of my snakeheads i doubt a trickle filter or sump would have been any cheaper!
cheers,
Dave

How would one measure the efficiency of a filter?

A while ago, I have put together a little piece of my "thoughts" if you would, to explain my thinking a bit.

After reading some posts on this thread, I though I would just throw up what I was working on, just to "stir" things up and see what people would think?

PLEASE TAKE INTO CONSIDERATION THE FOLLOWING: This illustration is not accurate, meaning the X values may not be the right corresponding Y values according to this function.

A horizontal asymptote, for those who may not know, is a value on a graph at which point the corresponding function will NEVER touch or cross. As X approaches positive infinity, according to my graph above, the function will never exceed that of 100%. Or more realistically, 99.9999999999999999999999...%.

Here is a Test of the 2 filters running head to head you might find it interesting

You don't have to drill to have a sump, there are many ways now from using pvc pipe to hang on the back stuff that works, not sure how well though. I think If I had to pick between the 2 I definitly would pick the fx5 though

erm... dunno if its relevant anymore, but my point was, no you cant have too much filtration, but to keep plenty of surface water movement i have 2 filters running on my 260l tank, i have an ex1200 (up to 500l) AND an ex700 (up to 250l). the 1200 has the spray bar, and the 700 has no end on so just squirts out and the harlequins love it

dunno what the turnover is though. but i have at least 90-95% water movement/surface agitation, and tbf, the tank looks alot clearer too

i have the ex700

its been setup in my tank 4 4weeks n it still looks murky

ive gt the ex700 ive had my flow at a fast speed n slow n its in the middle ov that.

I didnt realise i was lacking filtration so much. do i realyl need 2000 LPH?

i use a Fluval U2 400lph filter in a 200l tank(this was part of a multi buy deal). What filter/s should i add to make it correct amount and do i just add the 2nd filter and let it run or do i need to do anything to the new filter medium, how do i position a 2nd filter? can i use an external filter with sand?
Im also skint right now (x mas and other halfs birthday) so i cant get some super dooper filter, i also dont want a very loud filter as the aquarium is in the sitting room.

If i put a U4 next to my U2 will it make the U2 useless or will they both work.
also with so many filters and the increased water disturbance will it unsettle my fish such as silver dollars?

Idiots guide level replys please and thanks for the info
