Looking good Chris, the scape has grown in well and will look great once the hydropiper gets a move on haha, the wooods looking rather grand too 8) If I could I'd have dozens of nanos set up, there great little things. 8)
EHP is a strange one I havnt found much searching on google really, and as you say with the Co2 and fert decent light ect you'd think it would be fine but it doesn't really entertain you much. I've had no co2 now for a good 3weeks and its still just behaving how it was when I had co2.
I've started a lunch box with a few pieces of EHP and if I can get them to play ball then ill take the rest from my tank and replace it with HC, what was your HC set up like?(substrate,dosing wise) I've heard moist potting soil is a good.
Cheers Chris
