I just finished setting this up today. Got it for free a few months ago after helping clean a family friend's attic. As soon as the bacteria colony expands I'll hopefully be getting a pair of Betta simplex.

ha, thats cool! why the sponge filter tho?
sweet. i like the little path on the bottom.
WOW, great looking tank, it brings back many memories. I had a ten gal. like it in early 70's. It was given to me by an uncle and started my interest in the hobby. I can't wait to see it filled once the cycling has finished
i suppose i didnt look at that well enough lol. the red sea nano would have been my suggestion although the thing makes a lot of flow in open tanks, nothing a little diy couldnt fix tho...
