Well I had done a 50 % water change a few days ago(risky I thought myself ) but that brought the alk down considerable, since then seen then a response in two loney mushrooms (they opened) I also have did 2 smaller ones water changes like 20% So I guess I am on the right track.
thanks all.will keep you updated.
