You say there are 4 stages:1. Trophont stage: seen as the mature parasite attached to the fish. cycle timeframe: aprrox 7 days
2. Tomont stage: swims in the water column for several hours until it can find a place in the aquarium to settle. It will then attach itself to a surface in the aquarium.
cycle timeframe: several hours
3. Tomite stage: products of the parasite reproducing. They become free-swimming in the aquarium as theronts.
cycle timeframe: approx 4 days
4. Theront stage: free-swimming protozoans that must locate a host fish or die trying.
cycle timeframe: several hours
So in a tank with no fish there is no Trophont stage possible and therefore ICH must be in one of the last 3 stages, correct. So without a host, shouldn't the ICH be dead in: Several Hours + approx 4 days + Several hours???????
So why the need to keep the tank empty for 4-6 weeks as some recommend?????
According to the info provided, 5 days should suffice in a tank with no fish.......
PLEASE explain the reasoning behind the longer waiting period as I feel that I must be missing something!!!!
THANKS!!!!!
