I ask because according to the following protocol formalin needs to be in qt tank all the time at 25ppm and 6 dips at 200 -250ppm are needed.

the protocol describes the following:
"Chemical Treatments - Formalin
While formalin is toxic, carcinogenic and an irritant, it is, however, one of the best treatments for Brooklynella hostilis and Uronema marinum. It can be purchased readily from your chemist and some off-the-shelf cures contain it or a related chemical (paraformaldehyde or gluteraldehyde) so a read of the labels or data sheets of some products is essential if you want to use it.
The best way to use this chemical for Brooklynella hostilis and Uronema marinum is as a formalin dip followed by a long term formalin bath (see environmental treatments).
To use it as a short dip in seawater, make up a bath in seawater at 200 to 250ppm for 1 hour. The dip component of this treatment regime should be carried out on days 1, 2, 3, 5, 7 & 11 after each dip the fish should be returned to a quarantine tank to which formalin has been added (see below).
For the long term bath component of this treatment, add 25ppm of formalin to your quarantine tank (it's toxic to some invertebrates and algae, including most coralline algae species, so cannot be used in a reef situation)
Remember liquid formalin (which is how you will get it from the chemists) is 37 to 40% formaldehyde and you want 25ppm so you need to add 0.0625ml formalin per liter rather than 0.02ml to get the correct dose."
thanks for the replies
