Hi, this may not be the best group for this question but i couldn't find a more obvious one, i have had my GHL for about 10 years over 5 different tanks so its got lots of data / settings that are no longer in use, is there any value in doing a reset to default and starting from scratch? or can i just do a big tidy up exercise, i ask as i have had some strange random issues with various things in recent years and wondered if its just got itself messed up (or "fragmented" to use a windows term)
