Calculating the maxium weight limit of your enclosure.

This chart excludes terrariums since they are not meant to hold water and are thus unusable.1gal of water weighs approx 8lbs.10gal aquarium- 80lbs max weight limit.20gal aquarium- 160lbs max weight limit.29gal aquarium- 232lbs max weight limit.30gal aquarium- 240lbs max weight limit.40gal aquarium- 320lbs max weight limit.50gal aquarium- 400lbs max weight limit.55gal aquarium- 440lbs max weight limit.70gal aquarium- 560lbs max weight limit.75gal aquarium- 600lbs max weight limit.90gal aquarium- 720lbs max weight limit.95gal aquarium- 760lbs max weight limit.100gal aquarium- 800lbs max weight limit.120gal aquarium- 960lbs max weight limit.129gal aquarium- 1032lbs max weight limit.150gal aquarium- 1200lbs max weight limit.This chart is not intended to indicate that these aquariums can sustain the weights listed without proper support via a stand only that they are rated to hold the weight listed while properly supported.

Ok your next assignment is to calculate the weight of the substrate for each tank - if each tank had 8" of properly moistened substrate. Go!

@finalfantasyxii, basing my calculation only on play sand your looking at 1gal of water per 50lbs of play sand to properly hydrate it which means your adding 8lbs extra to the sand.A ten gallon would need one 50lb bag of play sand to get eight inches across the bottom add in the weight of the water added to hydrate the sand and your at a total of 58lbs.Double this for a twenty gallon and your at 116lbs of substrate water included.For my old forty gallon it took six bags of play sand or four bags and six bricks of ee so the weight for sand only was 348lbs water included but since ee even when hydrated weighs significantly less than dry sand the six bricks would only add about 18lbs water included.My 129gal takes 12 bags of play sand so your looking at a substrate weight of 696lbs water included.

I knew you would be able to do it! You are so awesome! I am totally going to use this info. Thanks!

I'm not really that good with math I just like doing calculation it exercises the brain.lolIt's easy to do the math when you've owned a good size range of tanks and have done the substrate depth mentioned.

Wow 12 bags? Are they the fine grain playsand from like toys r us?My 92 gallon takes 4 bags (of regular home depot playsand) and 2 bricks of EE to fill it to 6 inches. Add 1g of water, well 2 if you include what's in the pools, and all the other junk, it's probably around 175lbs total.I was always worried that all the sand would break it! But yeah then I realized they're meant to be full to the brim with water which would weigh way more than the sand. Lift with your legs!

@JMT, Nope I use the Quick Crete brand play sand from Home Depot and when first set up my 129gal tank I'd only bought seven bags which only gave me a uniform depth of six inches so I had to go back and buy five more bags to get the ten inches of depth I currently have.I actually need to up my substrate depth to twelve inches because my jumbos are having a harder time lately with the substrate depth where its at.My tank is right at 26 inches tall so I have so overhead space to play with but I'm thinking about sacrificing that for the extra sub depth.
