So, I am giving in and will be getting a proper filter for the 20 gallon.
Currently, I have the filter from my 5 gallon marineland tank in it to help with the stinky water issue. It seems to work but i should probably be using something rated for 20 gallons
I am more interested in keeping the water free of as much debris and odor as possible then I am in cycling and reducing water changes. I dont mind water changes
Any reviews on these filters?
I think what I am using is a mini version of the penguin filter. It has that bio wheel thingy. Also, I'm kinda worried about them getting stuck in the intake section of the filter. I originally stopped using the marineland one because I found my HM male with his long fins sucked up into the lower part of the filter. He was fine but I am afraid someone will get stuck in it and drowned. It's an all female tank so no long fins, but still...
I can find the marineland and tetra one locally but a sponge filter I would have to order. I cant find one anywhere.
