Formaldehyde based medicines

Postby KittyKat » 2008-06-19 13:44

Has anyone here ever used formaldehyde based medicines? What have your experiences been with them?

I have recently come across two cases where these had been used and in both cases they seem to have made matters worse and in one of the cases it looks like the tank has crashed and is re-cycling. This can obviously be devastating, especially if this happens to someone who doesn't realize what is happening. What sparked my suspicion was that in both cases the fish started showing signs of the "new tank syndrome" and in the one case where I was given the nitrite readings, there was a spike in them a week after the formaldehyde was first used. I am not surprised that there was no ammonia reading as even amounts of ammonia so low that they will not register on the test can be very damaging to fish and especially if they have already weakened immune systems due to a fungus/bacteria etc.
Formaldehyde is known to be toxic substance that is used for biocide (used to kill living organisms) and is known to have an effect on blood acidity. It is most commonly used to treat ich, but in both these cases it was bought as a general disinfectant. Should it really be sold as a general disinfectant when it is so deadly?

Hello. Read this topic lastnight. The formaldehyde rang a bell, having checked again on the treatments I stick to with my own aquarium, waterlife's protozin is my favourite for treating whitespot or velvet. It does contain formaldehyde, and back when I was keeping cardinals and clown loach I used to use it quite often. (I was regularly adding more cardinals and they nearly always broke out in whitespot a week or so later.) In my experience I never had any of the problems you mentioned. I test my water every week or so and have not had any readings for nitrite or amonnia.
Next time I use any such treatment tho I'll keep a close eye.
