1.What's the Max dept?
It is considered to have a safe depth limit of about 10 meters. Do not try to use it in deep diving. It can be used as a spare air source for deep diving within 30 meters.

2.Can the valve be removed so that the interior of the tank is visible? This is a requirement for air travel with a scuba tank.
Yes, the breathing head and the bottle can be separated. Convenient to travel and carry.

3.Where should you store it when not in use?
Typically scuba tanks should be stored in a dry place at least partially full. 

4.Can you refill the tank with the manual pump as much as you want? or you need to go to a store to refill it ?
Yes, you can use manual pump to refill the air manually or you can use converter and visit any diving shop where they can refill the air. With manual pump it will be longer, but any option is perfectly fine.

5.Are there issues with breathing aluminum dust?
It uses multiple layers of filtration to ensure breathing safety.

6.How many minutes of air does this tank provide?
That is completely dependent on the user. Size, breathing volume and rate, amount and type of activities, depth of use, etc. all contribute to "time."Generally,it's 8-10 Minutes.

nice little tank :)

Saw similar product on youtube and bought this one.
The good: well build, the wall is thick and thread is well made. All the valves is heavy and solid.
Takes 20 minutes to fill it using my compressor for pcp airgun.
Last about 8 minutes in community pool.
Easy to use, even my 9 year old boy can use it.
Cons: not sure its from my compressor or the bottle or valves, there is an oil smell in the compressed air.

Nice color

My dad recommended I get a small scuba tank for cleaning my pool. When you’ve got clean underwater or fix something, you don’t want to always drain the pool. Having a tank like this let’s you easily go under water for a short time and do what your trying to do.

Overall it’s nice. Bright green is a cool color. Feels good.
