so excited to be upgrading the hermies from a 40 gal to a 75 gal. One question though if my 40 gal is 6inch substrate how much more substrate bags should I get to make the 75 gal 6inch?

According to online calculator you’ll need 300 lbs or (.111 cubic yards) of sand for a 6 inch depth.

Do you have the online calculator website? I'm going to be upgrading to a 55 gallon tank and need to know how many 50 lb bags of sand I'll need. Thanks!

300 would be 6 bags. That doesn’t sound like enough. ???

I'm not sure, because I'm no expert, but awesome set up! They'll love it for sure!

Thanks! It said 33 lbs. That doesn't seem like enough though. Hmmm...

I upgraded to a 55 as well. It should be about 4 bags of 50lb playsand for 6 inches straight up.

I think i used 3 bags and 2 bricks of EE, but now i want to make it 8 inches

6 should be right on the money (ish). But you should totally add a couple bricks of EE as well to add a bit more depth while you have the chance. It’d be a royal pain to add/mix later on if you change your mind after the crabs are burrowed in.

Although not necessary ofc. I’ve tried all EE, all playsand, and partially mixed/partially separate. They’ve by far preferred the mixed imo.

O wait.. it’s already been set up

Looks nice

I’m opting to use half of the hood leds on my 55g at a time, although they havent been proven safe or unsafe as far as i could tell

I average one 50 pound bag for every 10 gallons of a tank. When you start getting into larger tanks like 55 and up the estimate ends up getting a bit off. Like everyone said 6 bags should work out. I always like to have an extra bag of sand laying around for emergencies.
