Started with a crushed argonite sandbed (approx 1.5" deep - grain sizes 1.5mm ) in my 90gal tank (brand new, still cycling) with 50lbs porous pacific LR
about 4 weeks ago.
Friday I found a deal locally on some old castle/southdown sand and added 80lbs right ontop of the original substrate. I now have about a 4" to 5" bed.
Question is: Should I leave them separated, or stir them together? The fine/sugar sand is sitting ontop of the crushed argonite.
Thanks in advance.
I will be adding another 40lbs live Keys rock in a week or so.
