Eventually it turned a bit too jungle for my liking so I'm starting again. Less plants this time so I can stay on top of it. I won't do any splitting and only use cuttings to replace rather than spread. And I want the frogbit back now that the duckweed has finally gone. I will stick some anubias onto the ceramic pipe. That;s strategically placed because its where the water hits when I do a W/C. Tested today and does a great job, zero mess after adding 120 litres from the top.
I have also ordered an Aponogeton. As its no longer an SA tank I don't have to worry that its out of place

. Yeah yeah - I know anubias isn't either, but everyone needs some of that!
