Hiya, i have some live plants now - i didnt at the time of taking the pic.
No its definately the unit. I have tried replacing the bulbs and changed the fuse and then changed the whole plug (just incase, lol) but i seems that it is the unit

Ive found one for £48 - i think thats gonna be the cheapest i can get it.
Ive not had mush look with this tank to be honest. I had to replace the heater just before xmas, it just wasnt heating the water and it was on the highest setting.
