2 Hrs a day...That's a lot...
Several of my tanks are paired and the smaller ones share the fuge with the larger ones...
So to test and adjust salinity,cal,alk on one...two or three are done at the same time...Same with water changes...
Low bioload, good filtration,Skimmer, Large cleanup crew, feed every other day and the stability of a large water volume keeps maintainence/emergency work to a minimum...
I spend maybe a half hour a day, cleaning glass and top off water (Auto top off coming soon
) A little more over the weekend if I'm servicing equipment (cleaning pumps etc...)
I think "feeding" all these little buggers takes the most time...
