I posted this in another section but just realized its a bit more appropriate here due to the questions regarding how much rock a tank can hold. Im trying to delete my old post but it wont let me> I am new to this forum. I have about 350lbs of rock/slate. Its a 125 gal tank. The caves go all the way to the back of the tank but its hard to tell with the pictures. Its still a work in progress; I need live plants still and a couple pieces of wood. I have aragonite substrate so I am hoping this will counter-act ill effects of the tanic acid leaching from the wood. I am only going to add the wood if all of the acid is leached out first anyways so I am assuming I will be alright!? Any ones ever use drift wood? Anyways I have no clue what to put in here now (fish) I took a million pictures (A few too many I believe so sorry ha) let me know what you think! I am open to suggestions. Im hoping to have it finished in a week or so.
