fat walrus,
Sure, as i understand it. The life cycle of parasites speeds up as the temperature increases. so, theoretically, the faster their life cycle the shorter the time making their nuisance existence in our tanks.
But, high temp alone will do little to eradicate them. You have to couple that with another trick and their are two. First and the most effective is UV sterilization. I've used them religiously for 30 + years. The second is a lowered
salinity, eg, 1.020. Some common parasites have an exoskeleton and at the lower
salinity don't have the ability to produce a strong exoskeleton making them weaker and perhaps not able to borrow into our fish. I've used these methods successfully for years. However, in the last 10 years or so I've gone to more powerful UV sterilizers and stopped keeping my
salinity lowered.
That's what I remember about this subject.
Hope this helped.
