there hasn't been any knock on effect on the cycle... yet. So rather than give yourself more hassle than it's worth, I'd hold off til you're fully cycled.what about thinks like slate then and rocks then?
i currently have some plastic ornaments in the tank, would it be a good idea to take them out when i begin cycling until its finished?
Wood again isn't a great idea as bogwood can drop the PH level a bit when during a cycle were trying to keep it up if we possibly can. With regards to ornaments (non wood) be careful not from a cycle point of view but the high ammonia levels can bleach anything plastic ruining there colours if there in there for any long period.
