Hi Jek, I really like the look of this scape so far! I actually started mine as a low tech but then decided to add some co2. But going back to some of the discussions early on I'm not going crazy on how much co2 I'm injecting. I don't know what you have your light set to but I found 30% about right for low tech with the twinstar. I'm also thinking of ordering a cabinet for my ada 60p from Green Aqua as my current one (IKEA Besta) is showing signs of water damage and let's the overall appearance down. I'm a little worried about moving the tank to a new cabinet as my scape has a few large rocks in it, may have to wait untill I rescape! Did you go for 70 or 80cm in height?
