Thread: Substrate depth

Is there a recommended minimum depth for gravel in a tank?
I currently have 1.5-2" at the front, 2.5-3" at the back of my planted 10 gallon. When I set up the new 37 gallon I'll need more gravel, but I am wondering if I need 3". Would 1 - 2" across the tank be OK? Plants are annubias and java fern, roots do extend into the gravel, but as the plants are mostly on rock or wood, I don't think I need much depth...

with just those plants, you should be fine with whatever substrate depth you want.300 gallon mega tank: build in progress
75 gallon community tank: tetras, danios, corys, platies, otos, pearl gouramis, bristlenose pleco, assassin snails, red cherry shrimp, bamboo shrimp
70 gallon growout tank: clown loaches, sailfin pleco
60 gallon goldfish tank: fancy goldfish
29 gallon frog tank / 10 gallon tadpole tank: 1 leopard frog, 1 tadpole
10 gallon and 5.5 gallon betta tanks: 1 male betta each, sometimes snails

It really depends on what plants you wish to keep in your upcoming 37 the depth and quality of substrate necessary. Heavy root feeders like the sword plants need a fine, iron rich substrate at least four inches deep. Epiphyte plants like the aforementioned anubis and Java moss don't need much or any substrate at all, as said.
