hi all,
This may be asked many times before !!
Has anyone used Formalin to treat fish disease before ?? Many website suggest Formalin to treat external parasite/disease!
Do it work well on velvet, gill/skin flukes disease??
My friend use (100%) formalin to treat his fish but sometime the fish is burnt from over dosage. He told me that it can also easily kill a tank of fish if not careful!!
Also will a LFS stock formalin ?? if not where else can you buy it ??
