Gravel vac

large tube attached to a smalle hose..gravel vac work of siphon and are very useful for water changes and cleaning mulm from the gravel.

a python device is a gravel vac that also works as a hose to replace the water removed during the water change and vac of gravel.

once the vac starts to work you simple push the large tube into the gravel..it will pull the mulm out while th gravel falls back.
 
a regular gravel vac basically uses pressure to siphon water from your aquarium to a bucket/container. you either submerge it and use a pumping action with my arm to get it going or start sucking the air out of the end (which is what i do, doesn't disturb the water as much and faster, just be fast enough to get the hose in the bucket so you don't ingest water). after a siphon starts, you basically just vacuum the gravel of fish poop and organic waste. then get your other container of already conditioned water and slowly add it to your aquarium. a lot of back breaking work because your lugging buckets/containers of water around

a python vac is basically like a gravel vac only you can connect it to your faucet via a long hose. when you turn on the water, it creates a suction and you can begin gravel vaccing immediately. to add water to your tank, you flick a switch and it starts to add water from the faucet to your aquarium. you might think the fish will die from chlronie or heavy metal poisoning but that won't happen. before people start pumping water back in, they add enough water conditioner to treat the entire aquarium size. just guesstimate the faucet temperature to match your aquarium water as close as possible. and then your done, a lot easier (too bad i don't use a python yet...)

in any case, a gravel vac is a must for any aquarist.

I would love to invest in a python.

It basicly acts as both, a vac and a hose to put back clean water back into your aquarium.

If i understand it correctly. It hooks up to your faucet in a fashion like a garden hose would and has a switch so that you can vacum the water out of your tank and into the sink....or water spicit. Then when you want to add water back into your aquarium you just flip the switch and voala, you have water going back intoy our aquarium.

Saves endless trips with a bucket.

Correct me anyone if im wrong.

OH yea, and if you look up a couple posts, a member has already explained what it is...

You don't need a python just a regular gravel vac. You can get one at even Walmart for 2-3 dollars. With a garden hose there are to many unknowns. They weren't made specifically for aquarium use and could have chemicals and other things which may hurt your fish. They also don't allow you to view what is coming out of the gravel when you are cleaning. If there is a spot with a lot of mulm and debris, you are able to see that and target it specifcally until all the waste is cleaned.
