i have recently set up a new tank at my place of work - so budget was an issue. the substrate is jbl manadoo with clay balls (i think they are called kugel) i use easycarbo daily and profito weekly. lighting is by twin t5.
plant species are hygro, amazons swords, sagittaria and ambulia (l. sessiflora)
all were mail order and arrived very small and unimpressive - however all have grown on well and, several trims and replants later, things were going ok, until now !
i have noticed over the last few weeks that 2 or 3 stems of the ambulia, in the middle of perfectly healthy stems, started to collapse from the top downwards. the growing tips shrivel, the leaves droop and then the stem melts away.
this was not a major worry, just confusing as i don't know anyone who has had trouble growing ambulia (including myself in several other tanks before!) but i noticed at the end of last week that many of the stems appeared to be drooping and on arrival at work today over half of the planted area has collapsed, broken away and floated to the surface !!
all other plants are fine (exept the red amazon which doesn't stay red for long - not surprising considering the lack of nutrient in the substrate)
the only thing i can come up with is that i have heard some true aquatics don't do well with liquid carbon, although i will admit to not fully understanding this.
can anyone help ? i would really appreciate your thoughts.
