In an otherwise healthy tank I keep loosing small fish to attrition. Larger fish are quite healthy Cory's, angles, betta, frogs, loaches, south american cichlad's
but two types of tetras, white clouds, pencil fish, I've been losing about 80% out of any group over periods of several weeks.
I'm wondering if adjusting the KH has anything to do with this?
some basic parameters:
Ammonia 0
Nitrite 0
Nitrate 5-10ppm
CO2 currently around 30ppm per drop checker. ph 6.6 at dKH 4
KH = 8.5
GH = 9
Ph = 6.5
Thanks
