Sure if you crank it high enough it'll slowly start to die off, but you might lose some fish in the process, and there are some strains of ich that just cant be killed with heat and then you're completely wasting your time.
Why dont you just add salt?
Not necessarily. This is easier said than done. Ich can still come back once your fish becomes stressed. Heat itself is not completely foolproof enough to destroy all the protozoans. Use salt or meds but do NOT combine salt with any meds containing formalin.SteveR;3907496; said:If it doesn't come back in a week, I must have killed it right? It can't be "dormant" in any way like they used to say if I didn't get all of it?
Yep, this is correct. I don't advocate use of feeders for this very reason. Many people can insist on doing it but they'll eventually learn the hard way unless precautions are used to prevent parasitic infections that are far more damaging than anything else.SteveR;3931749; said:Thanks Lupin, I understand that, what I meant was after it has gone, say for arguments sake 32 degrees + salt for 14 days and water changes, it's gone, and it literally cannot come back through stress alone. You would need to add a fish that had it in it's system (wether visible or not) or a feeder etc. Correct yeh?
