okay Ive been looking at sponge filters for a divided 10 gallon I want to setup. I have many choices. I'll post links and talk about them, you help me choose.
I really like the double sponge concept, suck more yuck from multi fishes and help with keeping good bactria in by cleaning only one sponge one week then the other the next, reducing any dramatic changes in the water, less bad spikes. note the adjustable bubble outflow valve
this design is really nice because it has clear body and tubes, also it can it can sit nicely in a corner,looks better. I like the multi layer design to filter better, the gravel at the bottom keeps good bacteria in. note the adjustable bubble outflow valve.
same as first one but only single sponge
standard sponge filter but its a corner one. note that it has no adjustable bubble outflow valve.
I like the first two the best, both diffrent yet both have pros the other doesn't...hard choice. note the first one is cheaper than the second.
please tell me your thoughts.
