Mercfh Posted June 3 Share Posted June 3 So right now I have a Fluval 407 for my 55g. It's got a lot of plants and isn't hugely overstocked. But I was wondering if it would be ok if it was just this filter alone. I have a Aquarium Coop large sponge filter in there as well....but even after cleaning it just doesn't do much, so I was going to replace it with a air stone. Do you think it'd be ok? Im not SUPER stocked I have 10 corys a few loaches 1 whiptail cat and 2 Raphael cats (and 6 serpae tetras) so there isn't a TON of waste. Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted June 3 Share Posted June 3 I’m sure the 407 could handle that no problem. I also think that if I'm going to run an air stone, it might as well be a sponge filter. Regardless, I’m sure the 407 can run that tank by itself with no issues. 2 Link to comment Share on other sites More sharing options...
Tony s Posted June 3 Share Posted June 3 I’d leave the sponge in. Not for any filtration. Leaving it in and going keeps it full of beneficial bacteria. Then if needed you could use it for a quarantine tank. Or even starting a new tank. Just lots of ways to use a seeded sponge I currently have 2 spares. Had 3, but instantly cycled a new guppy tank with one. 2 Link to comment Share on other sites More sharing options...
Beach Cruiser Posted June 3 Share Posted June 3 The two 407s on my 100ga work great, you should be fine. 👍 Link to comment Share on other sites More sharing options...
Mercfh Posted June 5 Author Share Posted June 5 I guess a follow up question would be if there are any other sponge filters people like? I just sadly haven't had good lucky with this one. Maybe a smaller one would suffice (this one is a large) Link to comment Share on other sites More sharing options...

Maybe a smaller one would suffice (this one is a large) The ac coop sponge doesn't really do mechanical filtering, especially if you have another finer filter running. It's mostly biological. And one sponge in a 55 gallon just really isn't a huge amount of flow either. I keep both a sponge and a finer internal fine pore filter in my tanks and it seems to work great. That way if I clean out one the other has all the bacteria in it still. Best of both worlds. Link to comment Share on other sites More sharing options...

All the parts "fit" that size tank rim and so on. Link to comment Share on other sites More sharing options...
