I wanted a way to push myself to make smaller but more frequent water changes as the ol' bucket method was getting a bit tedious. I went to 3 or 4 local pet shops that stocked fish and came across the Marina Aquavac which looks and acts exactly like the Python NoSpill system (dig Hagen buy them out, or get a licence to this product?)
Anyways, the prices varied for this product by quite a bit between the stores. As if nobody was purchasing them and had no idea how to price them. I find my 50foot Marina Aquavac for $62CAD which was the cheapest I could find in town. Petland had one for $99, non-chain pet store had an Aquafin (or was it Aqueon?)kit for $89 and another place was $80 for the Marina.
The kit comes totally assembled and because of this includes somewhat vague but decent instructions.
Starting it up was a cinch, no more sucking on the end to start the siphon, just turn on the facet and away you go. If you have multiple aquariums just lift out and switch over and it will start siphoning on it's own again.
The siphon power is great, you get the normal siphoning force plus whatever your facet is adding to it. In fact, I accidently sucked up one of my dwarf gouramis, thank goodness for the shut off valve near the vac
Refilling your tanks is easy. You need to head over to the facet , estimate the water temperature and then switch it over to fill mode. If you have the valve near the vac in off position, keep your facet at low pressure, I felt as if it was going to blow a gasket lol.
I am very pleased with the purchase and really glad I can ditch the bucket method. I saved myself about an hour of work.
Here's a few photos

If you want to do a water change without a gravel vac, it comes with two suction cup attachments and a bottom guard.
Oh, and by the way - you can pull off the gravel vac it comes with and use an existing longer Marina vac if you have one.
