I have a few fish I'm trying to treat for internal parasites and was told to use metroplex with coconut oil infused with garlic to make them eat. I soaked the food in garlic/coconut oil and put it in the tank. They didn't eat and the oil has created a grey haze in my 90 gal tank and there is a film on the top of the water. Will this harm my fish and do you think my marineland 400 and marineland 150 will clear this up or will I have to start my tank all over again?
