Hi Guys,
Well thats my own fault for having a go half baked eh! well thanks for the ideas and the notes I will do that for sure did not think of that to be honest.
I think the air pump will be coming the weekend so I hope to have a go at doing it properly then.
I will do it as scientific as I can so if it goes wrong maybe it will give clues.
Thankyou again for all your help I really cant praise this forum and the people enough.
Best Regards
Richard...
