Reply With Quoteany reasons or benefits that you would like to see other than utilizing all 3 filters?
do not forget that by doing so, you'll need to maintain 3 filters and most probably pay 3x electricity bill (not much actually).
I have 2 canister filter laying idle and another for my 3ft tank!
Recently, I came across a article on filtrition system for ponds and the idea of joining all the 3 filters together struck me!
My intention is to join inflow from the tank to the first filter, the outflow of the first to the second inflow, second outflow to the third inflow, lastly the third outflow returns back to the tank!
This is done with the consideration that all the 3 filters have the same flowrate!
Please kindly share some experience and suggestions!
Thanks!

Why not run them as individual for the same tank? Atleast you down have to down the whole filter chain when maintaining.Originally Posted by tawauboy
Yippie!! Reptiles and Fishies!
3 filters wont work if you chain them because although they have the same flowrate.. they clog over time..and then each filter will have a different flow rate... which means you will probably be stresssing some impellers...
just run them individually..
My intention was to enable the water to pass through more filter medium, thus the nitirifying bacteria can better break down the nitrogenous waste.
Moreover, I was thinking that the benefitical bacteria can multiply more easily onto the new filter setup than to run another entire new filter whereby the bacteria has to be cultivated all over again!
Looks like its just another stupid idea of mine!
Anyway, thanks for all the comments!
Me not going to try anything funny!
Would rather have 2 idle filters than 3 spoilt ones!
ok.
this is what you can do:
1) remove the impellers from first 2 filters.
2) pack the first filter with coarse mechanical filter media and ceramic rings. this will trap the bigger debris.
3) pack the second filter with media, such as ehfisubstrat, biohome, for biological filtration.
4) pack the last filter with more ehfisubstrat and fine filter wool. having more fine filter wool will help in polishing the water.
do note that it is not advisable to impede the outflow from a filter. flowrate is usually controlled by adjusting the valve on the inlet pipe. this is why you should remove the impellers from the first 2 filters.

Thanks for the cool suggestion!
Am I right to say that the whole chain of 3 filters will only be powered by the third filter?
Will this be too stressful on the last filter?

There was someone who chain 2 external filter together. The 1st would be stripped of the impeller. He also maintain the 1st filter and the 2nd ones was kept running. Both filter have different media in them.

By "chaining" the three filters together, won't the flowrate be very much slower since there are more "resistance" from more filter medias??

Of course, they are created to operate individually. I suggest running them on their own. You could do maintenance with 1 of them and letting the other filter kept running until a month or more, then you do the maintenance for the 2nd filter.

Is it possible? As long as they have the same flow rate right?
This is a bit of an over kill but just thought it helps to keep the water really clean.
Any ideas?
why don't you put different filters at different suitable locations in the tank.
that will also increase the cleaning capacity.
@ aquastuff.org
A series of canisters together? Like a sump tank just a canister version?
I agree with Harsh, you might as well has filters at several suitable locations within the tank. That will definitely keep the water clean and optimise the canisters usage.

It might not work, because of flowrate issues. It will work if you use one cannistor to run two cannistors.

Connection in series has been done before. There was a member here who has used it, his nick is LSZ if I'm not wrong. 1 of the canister must be unpowered, meaning you need to takeout the impeller and shaft.

I had asked the exact question some time ago!

I have merged the two threads since the nature of their contest is exactly the same.
If you are going to daisy chain your cannister filter set up, please take note:
ONLY THE LAST FIRST FILTER CAN BE TURNED ON!!
Even if you are using the same type of cannister, the flow rate of each unit will differ due to the media used as well as the position in the set up. Uneven flowrate will stress the final filter and cause leakage.
As such, you will need a really powerful filter (or pump) at the begining of the set up.

I have dwarf cichlids in my tanks! Do you?
I thought it should be the first one that should be turned on.
The instruction of the filter for controlling the flow mentioned that you should only restrict the outlet and not the inlet.
Apply the same principle, wouldn't that be better if you only power the first filter?

BC,
You are right. It's the first one one. Buttery fingers at 1.45 am!
