I have all my fish in qt while my tank is going fallow. I am at 2 weeks of copper power at 2.5ppm but would like to switch to formalin. I
Watched a youtube video from tidal gardens about qt and it recommended using 1 ml per 10 gallons then 50 percent water changes every 2 days replacing what was taken out at 1 ml per 10 gallons. This would be for 10 days.My confusion is because i read that formalin evaporates and needs to be replenished every 2 days. If this is true then after the first 2 days my levels will be half the recommended 1 ml per 10 due to me only replenishing the amount i removed. Does anyone know what amount i should be adding? Also i read i need to keep copper levels for 4 weeks to prevent reinfection. Should i wait 4 extra days before starting the formalin just so the total trwatment is over a 4 week period?.
Here is an abbreviated history for those who are curious how i ended up here.
I had about 10 fish die in a few weeks with no signs other than swimming in the power heads and fast breathing. I was told by a few people to treat it as if its velvet due to the high death rate and lack of physical signs. Right before i took all the fish and placed i to qt i introduced 2 new clownfish. i dosed the qt with prazipro and copper.While ramping up the copper dosage i lost another 3 fish then about a week into over 2 ppm levels i lost 2 fish including 1 of the new clowns. This time however they had skin damage that looked like brook to me. Im wondering if i introduced brook right before the copper treatment. I want to now treat with formalin after 2 weeks of copper.
