I have a 15g innovative marine tank. And I was wondering if it’s just me that’s incredibly picky about GHA and dirty-ish sand. I’ll post photos of what im talking about. I wanna know if im alone in this or if many others feel that their tank needs to have little to no algae to be a good-looking tank. And any solutions to rid GHA growing from my sand making it clumpy? I have 2 mega nerith snails that somewhat move the sand bed but I can’t figure how they eat. When on the glass I never see a mouth moving and actively eating like my astrea does.
