If the chain has loosened so much in such a short time, I would disagree with Amos and replace it. You might consider reusing the sprockets but I’ve always replaced both chain and sprockets at the same time as I’ve been told worn sprockets can make a new chain wear out faster. Seems people have differing opinions on this though.

As for the chains from XLmoto, be aware that the SS chain is a 520 so all the 530 and 525 chains are not for our bike. The DID ERV3 is very good, from what I’ve been told it’s basically the same chain as what most MotoGP teams use. They use the ERV4 which is hand built, but otherwise very close to the ERV3 which is mass produced. You can find it cheaper on eBay though.
