Jrkrouse13 Posted February 23, 2017 Share Posted February 23, 2017 Just starting out a new nano 20g long tank. I purchased about 40lbs of LS and am wondering if this is too much or a good amount. Across the board it is about 2-3 inches in height. I know this reduces overall water amounts which could be good and bad but does it make a difference if the sandbed is that large. Should I remove about an inch? Is an inch of sand worth the loss of the extra water? is that overall extra sand making a difference for the tank? Link to comment
Nano sapiens Posted February 23, 2017 Share Posted February 23, 2017 You'll find that many use shallow sand beds of 3/4 - 1-1/2" for small nano tanks (1" average in my 12g). A 2-3" sandbed (or even a bit more) can work, too, but takes away from vertical water height and can look unsightly to some (personal preference). Deeper sandbeds are typically used when burrowing fish/inverts are present. Link to comment
Maui's Reef Posted February 23, 2017 Share Posted February 23, 2017 My last 29 Gallon had a 5-6 inch bed to keep nitrates down. It worked beautifully. All you lose is height. Link to comment
Clown79 Posted February 24, 2017 Share Posted February 24, 2017 I prefer 1-2" sandbeds. Easier to keep clean with vacuuming. My 10g had a deeper sand bed and it was a PITA. Link to comment
