A friend recently bought some fish, and now they have what seems to be White-Spots/Ich.
He first noticed it and then promptly bought some medication a day after buying the fish, but he asked me if the medication would kill his bacteria in his filter and tank.
(He hasn't used the medication yet)
Here are the following ingredients, I currently have the medication sat on my desk as I wont allow him to use it at risk of killing his bacteria off.
The brand name is "eSHa EXIT" and it states on the instructions
"It is biodegradable and even after repeated use no remaining elements are left in the aquarium an no residues are left on the fish. EXIT can be used with the very sensitive fish (Such as Chocolate Gourami's) and very young fish due to its carefully balanced composition. Unlike many other treatments, EXIT does not contain formaldehyde which can be damaging to sensitive fish."
Ethacridine lactate 6.3mg, Malachite Green Oxalate 0.31mg, Methlene Blue 3.98mg in water.
I have never had white spots in any of my tanks so I had no clue what to tell him, or anything else to recommend either.
Are there any other remedies that can be used to 'kill' the parasites?
I heard using salt, and turning up the tanks heater by a single degree per 24 hours can help too, but I wasn't exactly sure.
He also has a Carbon Filtration (Fluval U series, I think).
