Ich treatment goes on…

The biggest problem with treating fish in large aquariums is the large water changes which all medications require after the course is completed.

Ich is most often treated with aquarium salt and/or medication, alongside a temperature increase to 30 °C, which is not good for most freshwater fish in the long term. A large water change during ich treatment will also help by physically remove the theronts and maybe some of the tomonts.

I did not follow the instructions exactly, leaving 48 hours between first treatment and water change in the hope that the medication would be able to kill more of the ich before I removed it with a large water change. The vast majority of the spots were gone by the 24 hours mark, and only a dozen were left 48 hours after first treatment. I was able to change only about 300 litres of water as I do not yet have a hose for draining and re-filling the aquarium quickly, so have to do all water changes with a 20 litre bucket.

The medication instructions advised me to wait a few more days before the next treatment, but I decided to re-dose immediately because the aquarium still obviously contained ich and the vast majority of it would have been in the   encysted stage, so would become released into the water very shortly.

At the 24 hour mark after the second doze, no spots were visible on any fish. I left the treatment in the aquarium for a few more days just to be sure that any free-swimming ich was killed. In the end, only four rams showed any visible signs of ich and all four recovered without problems.

Four of the six blue rams paired up on the third day of treatment.

The temperature was reduced to 25 °C once the treatment was complete.
