So, you may have heard - or maybe not - about my kids going out with friends about a month ago, and nearly a dozen goldfish following them home.
I asked in the Tea House about fishtank advice, but no takers.
YOU KNOW WHAT THAT MEANS!!!
Anyways, we're sick of changing the water in the pickle jars twice a week.

My dad just happened to have a 20 gallon tank sitting around, and I had a little pond/fountain pump taking up space in the shed. Seemed like a good start.
Just needed some substrate for the bottom of the tank. We live in the ROCKY Mountains. Why would we pay for sand?

That's why.
And that's AFTER allot of washing.
We anticipated the need for a filter, though, and had root beer floats for dessert last night. A bit of polyfil and some more sand - extra washed this time - and voila!

It's working!

I decided we needed more mechanical filtration, and also that the pump noise bothered me. Two birds, one finger... I mean stone.

One small coffee can for the inner housing, another larger on for the outer. Outer housing only has intake holes in the side that's now the bottom.

Stuffed the intermediary space with polyfil, slapped the lid on. It likes to float if you move it, so a rock for now.
draws water in THROUGH the substrate as additional filtering.

The pump outpaces the filter bottle by allot, but the aeration is good I guess.
By the time I get the water clean I can definitively say that the tank has been cycled.
Anyone know a tree species that'll live happily in a floating raft in a fishtank? Tropical willow of some sort maybe?
