JenTheDroid Posted November 15, 2021 Share Posted November 15, 2021 I only have a Giant Betta (Not a king. Giants are bigger) and a snail. I’m not sure if I’ll ever get more since I’m sure the Betta is territorial now. I was using the Seachem Tidal 35 and I’m just not liking it. I have a double sponge filter but don’t really like the look. I wasn’t sure if a sponge filter is enough or I needed a HOB too, but if it is enough would it be better to get one large one in the middle or 2 smaller ones in the corner. I was also considering a box filter since I could add other media but if a sponge cleans pretty well then I’m good with just sponges. Link to comment Share on other sites More sharing options...
Scapexghost Posted November 15, 2021 Share Posted November 15, 2021 One medium sponge filter should be perfect. Ideally in the middle but you could get away with putting it to the side 2 Link to comment Share on other sites More sharing options...
HotTunaCartel Posted November 15, 2021 Share Posted November 15, 2021 I think as @Scapexghost said, a single medium would be fine. I just put this in two days ago (In a 20 long) and this is how much it has trapped with just a ziss airstone in the sponge Yes, I'm dealing with algae currently but kind of amazed at the difference between the medium and small sponge filters.

anewbie Posted November 16, 2021 Share Posted November 16, 2021 One is good enough but i prefer two in case there is some issue - like i need to qt a fish in a pail or something - then i can take one out and use it. Link to comment Share on other sites More sharing options...
quikv6 Posted November 16, 2021 Share Posted November 16, 2021 I have a 20L with a bunch of pig....err....mollies and platies. I use 2 sponge medium sized filters in each back corner. I have one course sponge and one fine sponge...which seems to do quite a bit better visual job of mechanical filtration than when I had two course sponges. I like having the aeration/surface agitation on both corners of the tank. Link to comment Share on other sites More sharing options...
Streetwise Posted November 16, 2021 Share Posted November 16, 2021 With enough plants, this is a choice of flow, and visual impact. Link to comment Share on other sites More sharing options...
Flumpweesel Posted November 16, 2021 Share Posted November 16, 2021 Nothing to add about filtration but that is a very pretty betta and you never mentioned the mighty stature of your snail 🐌. Would you be able to sneak some bottom dwelling fish past your betta it's a lovely tank it be nice if something else could enjoy it. Link to comment Share on other sites More sharing options...
StevesFishTanks Posted November 16, 2021 Share Posted November 16, 2021 The cheapest and most powerful filter option for your tank and scenario would be the one you already own. The seachem tidal. I would put it on one corner and the sponge filter on the opposite side. Link to comment Share on other sites More sharing options...
