Formalin urgent help

1% is within the standard accuracy range.

In fact, any formalin solution above 10% or even 5% should work as long as you adjust the dosage.
 
Malachite Green may help a little, but is not really effective. It is somewhat effective against freshwater ich.
I would go with formalin only and not mix it with other medications.

Thanks, ive treated this evening with the malachite green. I will get some formalin tomorrow. I used it as a bath for 45 mins and then put my fish into another qt with fresh saltwater. How long should i now wait before treating with formalin and how many treatmeants?

Thanks
