Thank you for your help, I actually ordered the TMC reg from AE to stay on the safe side. I'm away next week working so my emergency routine of switching off 2/3 of the tubes, diy co2 and liquid carbon I can't keep up as I have no-one to administer the EC for me. I've been plagued with BBA in this tank before which as you know loves a good fluctuation(after long time nearly cleared up) so I was trying everything I could to prevent it as I had been running the co2 quite high previous to my reg packing up. Hopefully all my measures will have smoothed over that transition from high co2 to nearly none and the reg will come before I leave town.
Anyway off topic there
back to the reg, I should only need the d-connector to take to halfords as it is going on a FE I will let you know if it works ok. I need a spare set up to prevent this situation happening again anyway. I have the needle valve off the old broke reg and also another one at my office that was off one of those regs that use the old 8gram co2 bottles from way back in the day so I'll compare the threads and see if they match and then compare them with the halfords one and see if the thread is the same rather than having to change the 4mm pipe to the 6mm output plus a needle valve. Hopefully I can get a spare reg set up for emergencies with just the purchase of the halfords part and preventing me freeking out again.
I have heard that the knob on the Halfords reg may be a dummy I'll post up if that's the case and it is a couple of quid more expensive than other parts listed in this topic but it was worth putting up if anyone finds themselves like me needing one in a hurry, most people have a halfords somewhere local.
