u sure do.
use ro water
(i used a 5 gal. bucket with 2 gallons of water in it)
adjust your ph. very important to get it very close to the ph they have now
(u can use baking soda, ph up, dhk buffer etc.. I used ph up from aquarium pharaciticals.. cant votch for the rest)
you also have to get the tempurature the same as the tank they are in now
add an airstone so there is plenty of oxegen
heres what i read...
a freshwater dip can last anywhere from 60 seconds to 11 minutes, with 9 being a good timr. but if they start to get really stressed, take them out early. they will get stressed. when mine stopped swimming i moved him along a little bit. if it gets really bad though. pull them out early
id also recommend putting the fish in qt after its dip.... so you can observe it.. and also let the parasites die in the tank.
Id also love for you to get a second opinion just to be safe. ive only had a reef as long as you have... witch def. isent much as u know lol
