Daisy chaining filters? Better filtration, or stupid?

Hi everyone,

I was wondering whether I would get cleaner water if I

A) daisy chained two filters so that one filter's output was another filter's input so that the water would be filtered even more before going back into the tank.


B) simply ran two independent filters on the tank.

My puffer fish eats like a two year old left alone with a bowl of spaghetti...

lol, awesome analogy.

You have to be careful about "daisy-chaining" filters because they may run at different gph's and so they won't run as efficiently as they are supposed to. Plus if one motor burnt out then you could wind up with a mess. What kind of filters are they? Personally I would just run them independantly for more efficiency and better circulation of water.

Hi mHeinitz57,

Currently I have a Fluval 403 and a Pro-Clear 300 running on the 55 gallon tank. I wasn't really thinking of doing it with these filters, but wondered whether it would be advantageous to do it in the future with new filters. My dream fish is a several foot long Diodon hystrix, and I imagine this fish would be more like a bear getting into a garbage can full of spaghetti :) I'm going to need some filtration...

It would depend upon what you wanted the filter to do. If you needed your trItes or Trates to fall and did not have any bio surface within the tank you could daisy chain them. You'd fill one canister full of mech type media and the other with your bio surface. If your water clarity is cloudy you'd need to have 2 separate filters. using a good skimmer will remove the waste forever. Filling a filter with only floss and carbon will help to keep water crystal clear. But IMO I'd do that with 3 filters. 2 with regular mech/bio and one with floss and carbon to be used as a "scrubber". They will need to be cleaned often, maybe one a week if they are larger in size. Rotate them so one is cleaned each weekend. This will keep the bacteria stable. Is this for the RedSea Cube?
