it takes awhile to get the hang of 'sweeping' the gravel vac above the sand to collect detritus. but not too much of a hassle.
the rampaging midas makes cleaning the most difficult. he loves to knock the hell out of the gravel vac/my wrist.
i will go back to black gravel in the future. for darker color and better substrate spitting. watching him spit sand around is kinda weak. meh
