Hi,
I got a fundamental question --
When should I change the water in my tanks? My 20 gallon has been running since May, 2011. However, I notice that the fish seem to look more comfy when I change 25% of the water twice a week rather than 25% once a week. According to the guy at PETCO I should be fine with a 25% water change once a week. (Hence the question).
For my 55 gallon, is it better to change 25% once a week, or 10% twice a week? Can more water changes help ease the ammonia etc. spikes once new fish are added. Or is it better to just stick to fewer fish at a time? (say 6-8 Harlequin rasboras on the 55 gallon).
Also, is it better to wait for 2 weeks instead of 1 week before adding new fish (like I have been doing).
Thanks
