    I am looking at setting up a rack with 40 gallon breeders, 20 gallon longs, and 10 gallon tanks for breeding pairs, and fry etc.
    I bought aqua clears (with pre filters) for them all but now am thinking I would be better with one main air pump unit to run corner filters or sponge filters instead so this brings me to my question.....

    I can't decide on sponge filters or corner filters for them all.
    What are the pros and cons to using either of these types of filters and what would be best ???

    **note sponge filters would run around $14 each and replacement sponge 4 dollars each
    corner filters are $4 each and I have poret foam I could cut to go in each plus I have lots of bio balls and ceramics on hand as well as lots of filter floss etc.

    So what way is best????

    I have a central air pump for my tanks also. You can get sponge filters a lot cheaper than that, try angelsplus, or The benefit to corner filters is the choice of media, but either way works so whatever you can get a better deal on I reckon.

    yeah not sure where your pricing sponges but thats pretty high, about double what i pay from
    depending what sizes ( and you get a better price for buying 6-10 and even better for more than that) it is around $7 and replacement sponges are $2-$4.

    I was looking at a local shop here in Manitoba.
    So price aside, what filters are better?
    I see most corner filters are only rated to around 20 or so gallons but also noticed that when looking at a hydro sponge 4 and 5 that the actual hardware looks the same? To me the only difference is sponge size, is that correct?

    Pretty much, not sure if it applies to the hydro sponges but a larger pore size allows for more water flow while the smaller pore size traps smaller debris and likewise clogs faster.
