On the box it says that treatment may be repeated up to two times with 48 hours between treatment and a 25% water change, does that mean that after I do a water change today because of the epsom salt I shouldn't use the parasite guard again, until I do a water change again tomorrow then use it and then not use it again after that? and his stomach has gotten smaller but it still looks a little bloated and he's gotten inactive after I used the parasite guard, should that be something to be worried about, and I didn't see his poop since then, I'm not sure if he pooped yet or not
