I have been wanting to put in a small pond in front of my porch - it will only be about 6' long, 3-3 1/2' wide and I'm going to try to make it 2-3' deep.
Q1. I bought a pump intended to move water to the top of a rock cascade - will that provide enough water movement to keep things from getting stagnant?
Q2. If I put a foam filter on the intake, is that enough or do I need a filtration system like in my aquaria tanks? (usually charcoal-based)
Q3. Will gold fish survive or will I need to bring them into the basement for the winter?

PS This project is dependent on the porch being finished, the electricity being run and a brother-in-law electrician who works out of town for weeks-months at a time!

Pump - It probably depends on how many gals/hr it pumps. In general, the more the better.
If it's 2-3 feet deep the fish should be fine for the winter.
As for the filter- I have no idea. I would think that some sort of bio-filter would be needed.

We have two good pond resources locally - I'll be sure to check with them before I set it up. Thanks!

What you described amounts to approximately two cubic YARDS of water, kars. Any idea how much that will weigh? (Hint: a half a ton!). Do you intend to enclose this small (?) pond or will it be more or less free standing? If the latter, it's likely to freeze solid in the winter, and your goldfish will not like that. The reason a two-foot deep pond does not freeze in the winter is because it's in the ground.

Here is where my pond will some day be - in the ground, stereoman, so it shouldn't freeze... My husband teases me because I dug it out some last fall and he says in looks like a grave. Only a grave for the spiderwort, 2 0r 3 azaleas I moved and a bunch of weeds!!
