I think i might cry!!!
You may recognise this scenario from my previous posts.
Two days ago I did a water change in my 54 litre tank. i changed about 21 litres of tank water with dechlorinated tap water . I planted all my new plants where i wanted them, added my moss and some seashells for decoration. The moss was the only thing that had not already been in a tank ( the seashells were from Stanleys, washed in boiling water before adding).
i added 11 drops of prophyll for the plants and 11 drops of optima amd 15 ml Quick start. I also had to clean the filter because it had got so blocked it had virtually stopped working (
) but i did this in tankwater.
Yesterday the fish were all a bit quiet. Today they have all been chasing each other manically and 'spawning', although no eggs have been laid.
I noticed about 45 minutes ago that one on the glow lights was breathing really quickly, so i tested my water. I tested this morning also and everything was the same (normal) except my KH has risen from 6 to 10. Then i noticed that there was a lump of fuzzy stuff on the end of my bit of mopani root( see photo).
I have lifted the filter slightly so there is definite agitation of the surface, have siphoned the fuzzy stuff out and replaced the 7 litres of water that went with it with dechlorinated tap water.
Now three of the glowlights and one of the phantoms and one of the corys are all breathing quickly.
Are all my fish going to die!!!!!???!!!
what the heck is going on with my water changes. this is the fourth time that this sequence of events has happened and the final result has always been dead fish.
What do i do??
