Just want to know how often I need to clean the water and stuff inside. I just have gravel and I'm using an air stone setup as well so how often should everything be cleaned? if its every few days to a week, is there anything I can add to not have to clean it so often?

Are you familiar with fish tank maintenance? In the pool you are describing, you really have to change the water completely every 2-3 days. BUT, if you got a filter (which I know you have to get a special kind for a salt water pool, but I'm not sure what kind that would be), you could cycle the tank (this is when you allow good bacteria to grow in the tank, which will then process the ammonia into much safer nitrite), which would allow you to get away with 10-20% water changes every week or so. This would require at least a 5 gallon salt water pool, as well as a considerable investment in the right filter, however.

There is much more information to be found about cycling a tank on fish keeping websites/forums. Definitely check those out before making a choice. Also, there are members here with filtered pools who may chime in later.

100% agree with Ellysara! Ellysara, you stole the words out of my mouth!
