hello, i saw you asked about a biocube before. i would recommend not getting it. that was my 1st tank and i grw out of it in 2 months. wish i would have just got a bigger tank from the start. also i have a 90 gallon tank i have i want to say about 110 or 120 pounds of LR with no problems and its been up for 4 years. my rock is bali rock though and is very porous so has more surface area on it and allows more flow through the rock. im not to sure about the sand though, i want to say 80 pounds but not 100%. also got sand and rock in my sump/refugium as well
