Ok paul, The colour was dark green in the morn out of the tank. I put it back in and tonight it was a pee green/ yellow bud. its strange. I think im just not getting my co2 to disperse properly.
This proves that where you placed the DC tonight co2 is getting there, take it out again - let it go dark green again - put it in the tank again tomorrow, but put it in another spot. To keep a record of where you have placed the DC, get a piece of paper, draw a rectangle (this is your tank) and mark on where the DC has been and the colouration observed, then analysis your results.
Regards
paul.
