Thanks X3NiTH for your contribution to this discussion. I definitely think I need something to buffer up the GH and the KH in the tank, I have been adding some SERA Mineral salts that I used to add to RO water when I used RO before so that is what is probably buffering the KH to 1. The Nerites are doing a great job at the moment of cleaning up the rocks, I have taken quite a shine to them.
This morning I did a water change and removed some of the rock at the right hand side of the tank which seemed to be in the way of the water flow. I am trying to look at this from every angle to rid this stuff from my tank. I even wondered if the plastic substrate supports from TGM could be leaching something in reaction with the Co2, but Jim uses them and doesn't have the same problems.
I have tried having the Co2 on 24/7 but on a lower bubble rate of around 45 per minute and it made no difference. I have just connected up my Dupla PH Controller that I have always used in the past and set the PH to come on as soon as it goes above 6.9. Speaking of your comment below
No it was not a mistake on my part it is definitely 6.75 at lights on and the PH Controller has just been calibrated with PH 4 and PH 7 solution so it should be pretty accurate.
The UV arrives next week so as things are I am going to try it anyway and post here for all to find out what happens.
Cheers,
Steve.

so I presume this is a mistake and you meant to say pH 5.75 at lights on.
