Naw no nanos for me Sam, just gonna use a Juwel reckord 60 24x12x12 for the moment, although I contacted craynerd re: the tank that he has for sale, I would be prepared to buy this off him but it depends if he is willing to post to the ROI, wait and see on that one.
For the money you can't go wrong with the light units from ebay IMO, basically its the same one as yours and included daylight tubes, I'm sure I will be V happy for the price I paid, the equivalent arcadia would have set me back nearly €250 inc postage online, a price I would not pay, nearly 4 times what I'm paying for the other unit!
Don't forget that you have to have a decent amount of PO4 in order for the nitrate to be used at all, still trying to figure out how Im going to run the CO2 myself in the small tank, will be a few weeks before I set the tank up waiting for the new ADA order over at Aquaessentials, I want to use Aquasoil with this setup.
