An unpopular question its seems but does anyone know what might make my Echinodorus leaves curl? My tank is thoroughly stricken and there is more wrong with it than right with it. I'm trying to work out what has gone wrong so I bought a couple of easy plants to see what would happen to them now that I have upped the CO2 and lowered the water temperature ( I have Discus fish so temp was quite high ) ANYWAY I put them in and they are sort of coping, one has sprouted some sort of flower thing and the other has long narrow rolled up leaves? Trying to find out what this suggests but when I use the search on this forum I can't seem to find an answer, other than a possible lack of CO2, my drop checker is yellow I can't have it higher I'm surprised the fish are coping to be honest. Any suggestions would be much appreciated!
