I have an eBook on Amazon for $2.99 that walks you through the entire process of killing ich and marine velvet for good. Check the link in description. I have saved many fish in many tanks by following this process on how to kill ich and marine velvet. Good luck to you all! Any questions let me know. I learned a lot about ich because my fish were in need of help. I finally found out what the issue was. I had a parasite in my tank. I lost a handful of fish in my aquarium. I couldn’t figure out why they were out of it and not eating, and dying after 3 days. garlic guard will not kill the ich parasite. thank you by the way for watching. I didn’t expect this video to help so many people. I am going to show you how to kill the ich parasite. if you do not remove ich from your aquarium it will kill all your fish guaranteed. this doesn’t kill the parasite, it just helps your fish to heal while in the quarantine tank. you must get all your fish out of your display tank and put them in the quarantine tank. it is here that you will dose the copper solution / cupramine by seachem. your fish must be kept in your quarantine tank for a minimum of 5 weeks! NO FISH should be in your main display tank during this time. You are basically removing your fish from the main tank to let the parasite die. The fish will be safe in your quarantine tank (the copper solution will kill any parasite in your quarantine tank.) once you kill this parasite it will never come back. no amount of stress will cause your fish to get ich if it isn’t in the tank to begin with! just a quick tour of the sump my tank is reef ready, meaning it is already drilled. eshopps 120 skimmer you want to get a skimmer rated for a larger tank than what you have so it cleans better.
