Hi all who are reading this. I'm hoping someone has a replacement light unit for my new ( well new to me) Rio 125 tank. I bought it locally and when I got it back I realised the lid is not the right one and doesn't fit properly. My fault as I should have scrutinised before buying but I didn't know what the right lid should look like. Anyway, now £100 down I need to find a lid and light unit. Does anyone have one they wish to sell or know where I can get one now cheap at all? Appreciate your help so much, can't put any fishies in until I have one as my cat can lift this lid!! Arghh
