Thanks Phoenix44 I think I will treat with furan2 but still I am unsure weather to do a bigger water change because of the melifx or is it ok to combine the two. I know its me I cant understand what you wrote Im too stressed over all of this you said ...do regular water changes, first after the second day and ten everyday if you wish instead but add furan in the replaced water...not sure of the and ten everyday was it ment to be then every day? Man Im sooo tired
