Hi, my friends!
As a safety measure, is there a maximum amount of pounds of rock per gallon of tank volume; that you must follow as a general rule when adding rocks?
Then, how many pounds of rock should be added in a 55 gal tank as an adequate and safe amount?
Does it help to put lighting grid on the tank bottom?
Thanks for your help!

you can put far more rocks in the tank than it can hold.

but 100-200lb would fit in their with no problems

there is a debate about eggcrate(lighting grid, and I think a lot comes down to the confusion over the word diffuse.

eggcrate WILL diffuse the weight of the rocks to a degree, though it will not spread the weight a huge distance, it will stop the weight of the rocks being concentrated on 1 point, it will instead spread it around the edges of the cube that its resting on, which is a much bigger surface than just 1 point of the rocks.

also, it will cushion any falls to a degree, and stops rocks from scratching the glass. another thing is it provides a "grippy" base for the rocks, so they dont slide when resting on the eggcrate.

I like to eggcrate more because the amount african like to dig. This prevents them from complete dislodging the rocks....
