Hi Brady,she is 5 years' old. The PH in my pond is 7-7.2, temp now is around 10 degree centigrade (the highest will be around 32 in the hottest days and the lowest will be around 6). The pond holds 45 tons of water and the average number of fish I have in the pond since she arrived in June is about 6-7. Now I have 13 fish, ranging from 40cm to 75cm and she is the biggest in the pond and the 2nd largest is 62cm.
I have not had the accurate readings of nitrite, ammonia, etc. I have checked hardness in a water lab during the summer days and the reading was 85, which was quite unbelievable, because I use underground water and I was expecting a much higher reading (the hardness of the tap water should be around 110, as I believe).
Anyways, thanks for your encouragement!
BTW, she has grown from 70cm to 75cm since June, which makes me very happy.
