#20, 真牛!! 牺牲的鱼约一千多条!! $1*1000 = $1000, $3*1000 = $3000. 佩服!
As I can see the water is main issue for fishes, when I was on vacation, 20 days, no water change, no food, my fishes are fine. Water still is very clear. Of course, you have to have good filter and plants to keep water clear and have food ( plants ) for them to eat.
In Ottawa, some area pH value is very high, like my area, it is over 8.X. It is not good for some fishes. Like discus, crystal red shrimp, ... they may die. If you want, you can spend more money to set up a good water filter system. I saw one guy he set up a almost automatic system ( over $3000 he told me) , if you are interested, please check

The tank is on first floor, the pipe links the tank and water filter to basement. Whole system is running automatically! He has
microscope to check water daily and has data log to monitor water condition....! He has powered timer plant food dose system to add six plant food hourly. N!!
