Hi Colu, thanks again for your help. One thing I noticed is that the full dose for Ich-X is approx 1mL per 8L which is the same for 'sensitive fish' in the blue planet remedy. Is that because of different concentrations of formalin and malachite green?

Hi, I have a 50 gallon planted tank with cardinal tetras, honey gourami, bolivian ram, sterbai corydoras, otocinclus and harlequin rasboras. About a week ago I noticed one or two spots of ich on 4 of my cardinal tetras which I was going to treat until I encountered a columnaris outbreak on some of my otocinclus and rasboras. I decided to treat the columnaris first given it was a more serious threat using nitrofurazone and kanaplex - thank you to Colu. I have so far had great success with this treatment and no further deaths or symptoms since. I have monitored the cardinal tetras and note that about 4 (out of 10) of them still have one white spot on each of them but otherwise seem healthy with no scratching and eating well. No other fish show any outwards signs of ich. My plan is to treat with a white spot remedy from Blue Planet (Ich-X not available in my country) which the active ingredients are: - 37mg/mL Formaldehyde - 0.32mg/ML Malachite Green - Dose rate of 1mL per 8 litres of aquarium water for sensitive species such as catfish and tetras. (1mL per 4L for non-sensitive fish). My questions are: - Should I wait to treat for whitespot given the fish have just completed a 5 day course of nitrofurazone and kanaplex? Or will they be fine to treat right away? - Is this treatment safe for corydoras and otocinclus? I note Ich-x has malachite green chloride which is not so hard on fish whereas this remedy includes only malachite green. Any help would be greatly appreciated. Thank you.
