i had one of them some time ago, unfortantly they don't work as well as you would think, but saying that i had mine under the gravel and it tended to push its way to the top i got annoyed with it lol

I had one too at one time, they clog really easy if you have hard water

I agree with the topic's title.... That is a really neat idea! It would be easier to encorporate into a tank, easier to hide, kinda fun to change around. Too bad they don't work that well, from the other two comments.

It takes a REALLY strong airpump to push water through even one length of that stuff. I do not know what type of tornado would be able to send air through the longest length - or any chained together.

I had a flexible one . It lasted about 6 months and then cracked. The plasticizer in the rubber was gone into the water and it got all stiff and crackly.

Yeah, I noticed that on the website that they only had REALLY long lengths. Even the smallest 15 inches is still abnormally big.

yeah but even a small one might b cool!

I've got a couple of those, they work just fine for me. I've been having more trouble with my air pump wanting to die...but thats what I get for getting the cheap-o pumps. I have a 15 inch black bendy tube that I don't normally use because its in my "spare tank kit" but my bigger one, I think its 22 inches works great and I've had it for a little over a year. It is annoying though becuase it works its way up through the gravel, luckily its the same color as my gravel so it doesn't quite stick out like a sore thumb.
