Thank you, I was looking at going up to the skagit and finding some pebble type for the base layer and then a few bigger rocks to make caves and stackable shelving for the tank. I would clean them obviously .Yes I use river rock, mountain rocks etc.. all the rock we buy came from the earth too. Just be careful what types of rock you use, most are good to go. but limestone wil raise PH and some contain minerals that may be harmful.
Have any pics? Looking to get some ideas....just picked up a 55gallon marine land aquarium kit from petsmart for 65 bucks (hip to save) has a deal buy online pick up in store and it drops it to 65bucks so I want to do my own landscape in this tank.I have river Rock in all of my tanks.... Just boil it for a while and then I add it in. Agates are my favorites
