I have adjusted this chain probably 5 times at least in the last 1000 miles, but keeps jumping back to the old setting? What am i doing wrong?

Heres the scenario: For example, If you look at the chain tensioner doohickey it looks almost like a 3/4 of a clock... with groove positions at 1oclock, 2oclock, 3oclock, 4oclock, 5oclock, 6oclock, 7oclcok, 8oclock, 9oclock and so on.

When I first got the bike, the tensioner pin was sitting in the 5oclock position, and after some riding the chain loosened up quite a bit. So i adjusted it to the 6oclock position which tightened the chain up some but still allowed some play in the chain.

I tighten everything up, TIGHT! and i send my son on his merry way. A week later, i check the bike and both tensioners are back at the 5oclock position again! How is this happening? Currently I am using a 1/2" breaker bar (both sides) on the thing and it is TIGHT when it leaves me.

Am i doing something wrong?

how do i keep the chain tension to the proper amount?
