Should I Deep Clean Filter After Fungus Invasion?

As the title indicates, I had an small fungus infestation in my Goldfish aquarium (White fungus, Ich, weird green one, you name it). Luckily I managed to save them all in quarantine tanks. Now it is time to put them back in the main aquarium which I already clean througly with Bleach. The question is: Should I also wash my cannister and eliminate all my bemeficial bacterias to start all over? or not? Thanks in advance

 

Back up. You bleached your tank? Did you then thoroughly rinse with Prime treated water several times? Because if not, you are looking forward to a fish kill.

Don't nuke your filter. Run a course of antI fungal treatment through your system, if you have concerns. Otherwise, carry on.

 

Yes I did clean it throughly. Concerning the anti-fungal treatment, which antifungal treatment should I use? IMPORTANT NOTE: I'm in South America, no Medifix, Dr All in One, or other products. Just Methylene Blue, Malachyte Green and some other Sera Products

 

Malachite green works on ich and most other pathogenic microbes. It's rough on invertebrates, so if you have shrimp or snails you're fond of you should pull them first.

So I clean the filter with Green Malachyte? I.thought that was the same as deep clean it because it also kills the good bacterias

 

When I had ich I didn't clean out anything from the tank. I did through vacuuming and that was that. Didn't touch the canister or nothing else.

If you indeed bleach the entire tank you might run into some problems when trying to restart the tank. Any residue of bleach will certainly destroy your BB in your tank. I would make certain that your tank is bleach free before restarting the tank.

You might run into a minI cycle. The substrate does carry quite a. It of BB. So before adding fish in you'll want to make sure all your parameters are good.

No. You COULD treat your TANK with malachite green after you hook your filter back up to it, if you are concerned about pathogens residing in your filter. But as nearly all of them need a fishy host to survive in any meaningful sense of the word, most people wouldn't bother. I wouldn't.
