Ok, I posted a thread asking this question but it turned into more of how I should change my filtration set up. Didn't answer my original questions/concerns. I am thankful for the advice but I don't see any reason to chance my filter types or my set up when what I have is already working.
I just want to add to it.
Im using what I have simply because I already have it and don't have to spend any more money or waste time changing it..
So my question is simple. I want to add another filter. But put it inline with an existing filter. (piggy back 2 filters together on the same line)
I have a few questions or concerns though.
See photo below, then what my questions and concerns are under that..

Info about tank and why Im wanting to add 4th filter:
The amount of filters I have on my tank now are fine. Does the job. (I have a high bio load and it does great with it)
360 gallon tank. 3 Fx5 filters on it now. (see my signature to see live stock in this tank)
My female stingray in this tank now has pups about every 6 months or so.
In the past, I moved the pups to a holding tank in my basement that was already up and running. (year round)
But we moved and I no longer want to have a dedicated tank running when I don't have pups around.
So I thought of just adding this extra Fx5 filter I had to my main system. For two reasons.
One for even more filtration.
2nd to keep the filter seeded for later use.
When we do have pups, I can take the extra Fx5 (C) and hook it to the holding tank and have a seeded tank up and running in no time.
My questions/concerns of adding the 4th Fx5 up as shown in my photo is this:
Should I run the pump motor on Filter C or not.
Would NOT running the pump allow filter B to effectively filter thru both B & C
Or would running both B & C pump motors cause a issue with flow rate thru the pumps.
An Fx5 turns over the water around 900+ gallons an hour (this is thru a standard Fluval Fx5 hose)
But if I had both pump motors running, would that standard hose still allow enough flow to feed both motors effectively.
B would be bringing water in and out, feeding filter C. But would filter C be getting what it needs to run properly or would over time it cause a issue with the motor..
That is my question..
