Thanks for all the advice and I appreciate the welcome. Sorry for not including background on my system.
I currently have a 10 month old fish only low bioload 300g system while I am continuing to work out the lighting enigma. (By the way Rob has impeccable timing with the lighting series. ) I'm hoping the weekly water changes of about 10% are ok until more demand is put on the system.
