Can Fish OD on Iron?
HELP!!! We've lost 10 fish in 8 days! 2 Runny nose tetra, 2 cardinal tetra, 1 platinum angelfish & 5 German blue rams.
No red gills, no sores on body, no flukes, clear eyes, fish eating fine and active. Examined last dead fish and if it weren't for the fact that he was dead, he looked great!
90g heavily planted, 2 fluval filters (internal & external), UV filter running 24/7, water parameters great before and after 50% water change, CO2 below 30.
Prior to beginning of deaths, I was dosing extra iron as Blyxa was melting.
Other new changes were Seachem Cichlid vitamins in water column and ZOE mixed in food. After the deaths started, stopped extras but fish continued to die.
Took charcoal out of filter after water change last Friday & replace with bio media.
Any and all thoughts greatly appreciated as we haven't got a clue as to what's going on.
