Update.
In total iv lost 2 rummy nose and 1 cardinal tera, 2 cory sterbai.
The original sick cory sterbai is still in the tank,
im not sure what to do with meds etc?
I think this happened due to a dodgy bottle of med
The 1 adolfi which looked like it was on it last legs is now ok.
All the plecs and other fish seem to be fine.
Today i did another 50% WC took any dead plants etc and did a full sand vac,
and a general clean.
iv also re-arranged my rock formation.
the carbon has been in for 24hrs now
im goin to leave the filters,carbon in till december 6th as this is my 6 month time slot of a complete filter clean of my 2 EX1200
Which is clean all sponges,bio-balls etc in tank water, renew floss etc and clean impeller/shaft etc
Just like to thank you wilder for all your help
cheer steve
