secondary filter suggestions?
I have a 100L/26g tank with an external filter that pumps 550L maximum flow rate, and has filter wool, bio balls and ceramic noodles as the filter media.
After reading up on this forum I have decided to get a secondary/back up filter, but I dont know much about filters.
I know there are a lot of types so can someone please help me out and suggest the best type of filter to purchase as my secondary filter?
I was thinking maybe a sponge on or something gentle as i dont want too much more flow in the tank, thoughts?

First off, if the bio-balls are plastic, replace these with just ceramic noodles; a sponge filter is fine but consider a filter that has at least the capacity of the current filter. In this way if something happens to one filter, the other can quickly take on the load (however, in that event, expect an ammonia spike for a few days.)

If you can find them, AquaClear filters are some of the best HOB filters. I've had mine for 7 years :), they make a model for smaller tanks so I'm sure it would work great. If you don;t want to add flow to the tank, just disrupt the outflow to flow towards a tank wall70 Gal Planted Rio Negro Angelfish Biotope with:

I tell you if you have a place to hide them you can't beat a standard sponge filter for both Bio and Mechnical. You can run them off a air pump or a power head and there cheap. I know of people running a 125 gallon with nothing else. I'm told the link below makes awsome sponge filters and you sure cant beat the price.
Opps!!! didn't see you where in Australia maybe if you do a search there is a distributor there anyway check out the link it has some good info
You know the Fluval C Series is a updated cousin of the Aquaclear I run two and love them even easier to maintain than the Aquaclear if you can believe it.
