Hi
I have been having trouble...my fish are dying during the night (tropical fish). In the last three weeks have had four die with two of those in last two days. Had water tested yesterday and showed nothing. Do water changes weekly (approx 20%) and nothing obvious showing wrong. Running a Jebo cannister filter, approx seven months old.
Had fish in Christchurch for approx 18 months and only ever lost one but here death is upon us!! Only difference in setup, in Chch had an under gravel filter and now have cannister filter, and piece of wood off beach which didn't have before. Water quality in general does not seem to be as good here as Chch either.
Any ideas or help, anyone have similar problems??
Thanks
