yeah, I have changed the water 50%, and clean the filter using old tank water last weeke end, and yes, the koi did calm down slightly i observed through the whole of last week, but not much difference before I changed the water. I did add salt and some soda bicarbonate to balance the water to 0.2% salt and 8dKh.
But the small kois and few others still not feeding much on the floating food. Only few bigger kois snatched up all the food.
But I discovered one important thing: all these months I never realised. Yesterday, I just happen not to switch on the tank lights because I'm changing the electrical plug, so the lights not on, but i throw in the food. To my shturprise, the smaller koi did come up to eat. And the rest of the koi too. They are feeding quite relax and not dash up and down. Previously ony the bigger koi will feed relaxly and others just dash up and down.
Now I'm going to experienting it with the lights: I'm going to get those switch that slowly on the lights and not suddenly just on the lights. Because I remember that time when I bought back the small koi, previously it is feeding happyily on the food, only after sometime when i suddenly off the light, it got scared and dash for cover, ever since then it never come up for food except sinking food. So yesterday, i did not on the light and it come up! i'm quite happy though. Hopefully after getting those switch, it will not get scare. Like the pond outside, sunlight only appear slowly. But for indoor tank, i hope can simulate to be sunlight, switch on and off slowly.
Just want to ask u guys, do u on and off your lights suddenly? and if u have small koi, they do get scared right?
