Hi all,
I'll admit to currently being a bit stumped with my fish. I changed my Nutrafin bottle ingredients on Sunday this week, using the usual yeast/sugar method and not the sachets. My CO2 levels then went higher than normal and showed yellow on my indicator. The previous day I had dosed (as per manufacturers instructions with water change etc) a second dose of Interpet No.8 Fungus & Finrot treatment.
I first noticed my fish breathing more rapidly on the Sunday afternoon once the new CO2 had been on for a while, the treatment on the Saturday had not shown any change in fish behaviour. I disconnected the CO2 straight away and after 30 minutes did a 20% water change. Initial change in bahaviour but fish were breathing rapidly again not long after the change. Last night I did a further 20% water change and put the CO2 back on but with much less yeast added to the mix: my CO2 levels stayed green and barely changed the colour of my permanent test (which I have cleaned/changed to ensure this is OK).
This morning my danio are all gasping at the surface and my other fish are all breathing quickly, with my cory darting to the surface more than usual (though not that often). pH is normal (7.2 without CO2), nitrIte and ammonia are zero, the water changes should have removed any chance of the treatment being the continuing cause, and CO2 levels are barely above those in the normal tap water.
I am now stuck. Could the high CO2 have caused longer term problems with the fish? Given that even after a day of the treatment being added the fish were OK, I am guessing it is nothing to do with the treatment....
Thoughts anyone?
