hi, thanks to all that have replied. im completely new to this forum thing.
i have attempted a photo as suggested by woodstock but the orange blobs are rather small at the moment, i cleaned the glass (silly me) so i tried a piccy of some on the live rock. The purple calcerous algae is growing on pipes etc and does not come off easily. the orange stuff scraped off really easy.
i recently put some red sponge in the tank, dont know the name of it but looks like red reindeer antlers. dont know if this has any relevance as blobs are orange.
thanks again for the help, when i get more time i'll describe my set up in detail, gotta work out how to use the profiles etc properly first. hazza .
oh heck, how do i get a photo from my documents to the message box
