Cjbear087 Posted September 8 Share Posted September 8 So I plan on buying this sand https://www.swelluk.com/swell-aquarium-silver-sand?gad_source=1&gclid=Cj0KCQjwlvW2BhDyARIsADnIe-JLLQig55ACLi-87U0WiTUh_vqPUJ9wKBcMbjm4TEixCF9KJJQ16jgaAoTEEALw_wcB#aquarium-silver-sand-20kg and I was wondering if anyone could work out how much I would need for roughly 3 or 4 inches (if that would be good for a planted tank?) the tank dimensions are 121 x 51 x 80cm. Thanks I plan on getting 20kg bags so if someone could tell me how many of them I would need that would be great. Thanks Link to comment Share on other sites More sharing options...
Tanked Posted September 8 Share Posted September 8 Try this calculator. somewhere on the bag should be a volume calculation. https://www.calculatorsoup.com/calculators/construction/tank.php Link to comment Share on other sites More sharing options...
TAB Posted September 8 Share Posted September 8 Well that's #60 mesh sand. If it was clean, dry, silica sand it would be 2950 per yd3 110 per ft3 Your tank is roughly 48"x20" so each inch of sand is roughly 960 in3 divide that by 1728 to give you .55 ft3 x110 lbs/1ft3=60.5 lbs per inch of sand. There are 2.2 lbs per pound so each 20 kg bag will give you 44 lbs. So each bag will give you about 3/4" of sand. Link to comment Share on other sites More sharing options...
