Cheers guys. The HM is being replaced as we speak (cheers Mr Worrall). The D. diandra coped fairly well, so I have left it in, but it now seems to be deteriorating after I gave it a trim to get some more stems out of it.
Yeah, I`m still happy with the look of the hardscape Mark, which is what is making me determined to get a scape out of all this (although my mind is already wandering on to the next one).
After another week of slow decline, I have come to the conclusion that the CEC of the amazonia has resulted in it becoming tainted by the mysterious additive. I have planted some of Stu`s HM, which has slowly declined, yet the stems I left floating for the duration have remained healthy.
There is still some HC grimly hanging on, but that was planted in the Xingu Forest Sand. I`ve decided to suck out all the Amazonia and hope to find an opportunity to replant some time soon. I don`t think I`ll be adding any Didiplis diandra this time. Crikey, this thread is probably more appropriate to the journal section now :!:
