I have a 10 g that I currently I'm dealing with flukes. I'm dosing with Prazipro right now. everything I read tells me that once done to use carbon to remove the meds. my question is if since I have 2 QT tanks that I'm using at this time. can't I move the fish once the first treatment is done and due the second treatment in the second tank and clean the 1st qt tank with a mild bleach solution and then read the saltwater? then use the first tank again for qt again. I plan on doing a 3 week cycle of prazi. won't a mild bleach solution work just as good and make sure all the bleach is out of it, and reuse it for a 3rd week of prazi treatment. then move back to second QT for bacteria out break from that point. also how long do I need to keep my DT Farrell since the out break of flukes. I have a shrimp, annema, and snails and crabs in there along with frags. I read that I need to get rid of snail and my crabs since they have shells and flukes might be hiding in there doormat until it finds another host to attack. is this true? a pic of the wrasse will be following when I get on my cell phone to post... it looks pretty bad shape but it's surviving.
