yes, completely tearing down my 55gal, increasing tank and sump size and adding a fuge.

im aware of the silt in the bags of dead sand, was planning on rinsing it VERY well.

im pretty sure all the sand and rock thats in my current tank is well cured. Even though the base rock im getting says its cured, I should still cure it here on my own as well?

Thanks for all the help.
