So I just spent 12 hours cleaning my tank. I scrubbed off so much hair algae and rescaped my 120g tank. What I am wanting to know is that the new flow pattern is really pushing around the sand bed. I was wondering it is would be ok to add new heavier sand. I have thought about getting a bit heavier sand. I beleive I am using the ocean finji pink and it is really blowing around. Can I just pour new sand over the old sand or will it cause a mini cycle. Or I live on the east coast next to some nice beaches that have some heavier sand, would that be ok. I am not too worried about parasites.
