glad i could help Tim. BBA has been my aquascaping partner for a long time now and it still hides in the background waiting for an opportunity. I am now working up a theory which seems to be proving right that even something as inconspicuous as not topping up my tank for 2 or 3 days will in induce BBA to jump out from behind the curtain, which im assuming is because there is greater surface agitation so more off gassing, as such fluctuating co2.
I already realised the hard way that turning up my pump which runs the reactor will also induce it, again only anecdotal but think the higher flow rate reduced the dissolution of the co2 in the reactor as more gets pushed through as bubbles. It seems obvious now but took me a week of head scratching to remember what i had done that may have caused it, then tried it again... bingo BBA!
Anyway apologies for going off topic for a minute Paul.
