Fantastic idea Gizmo! That's why I love air pumps, they're so immensely versatile; they save space, time, money and electricity hehe. You can even make your own sponge filters if you want to save a few pennies and rig it all up fancy...
I'm rescaping my divided tank, one half at a time! Do Kaze's half, take a rest (I tend to get rather achey after rescaping), do Echo's half, take another rest then proceed to dream of ADFs.
I'd still love to get an ADF one day, but I think for now I'll still have to pass... I honestly... am running out of space. My room is the smallest bedroom in the house but it has the most in it in terms of animals and plants
I've continued to "stalk" this topic and am still learning so if I'm ever lucky enough to take the plunge I'll feel completely confident.
