I promised an update, so here's the new tank.
I'm afraid I lost a couple of glowlights in the transfer (I think I should've done a big water change just before adding them as - despite readings being fine - there was probably some adverse stuff in the water from plants having died - see other thread on that).
But otherwise everything fine so far, with plants, fish and biogravel in. I've also tidied up the 19L a bit - though it probably needs a bit more work.
