Your idea of double filtration and mine are off a bit.
um thats one of two filters on the tank. That is rated for 50 gallons and the other is a 30 gallon in tank ... And of course I'd properly maintain it

Also it was just an idea I will convert the forty to a species tank and get a thirty and also set that up as a species tank when The time comes. I'll probably choose Axolotls or ACF Though I'm kinda leaning toward Axolotl I've wanted them since I first saw them.
