Nothing you can do but wait it out and do water changes until the AquaSafe clears out of the water. The skimmer will pull some of it out, so keep dumping the collection cup as needed. The water changes will help with rest. If you really put about 200g worth of AquaSafe in there, it is going to take a while. And if you put an excess in there, let this be a warning that you NEED to pay more attenion in a marine tank if you expect to have any sucess.
I would NOT put a piece of filter floss in the filter given your current situation, you could cause an overflow.
Unfortunately when you learn a lesson in saltwater tank, it usually costs you a lot of money, or takes a long time to clear up.
You really gotta take a step back and decide what you want to do in this hobby. Just recently you have had to move your entire tank because your parents told you to, you dumped way too much Aquasafe in the tank, and now you have to return items for you tank and you are not allowed to buy more? Not good trends, but we can help you out
