Thanks Eileen! I think I'll check out both KRC and RCP rock in the local area. Looks like RCP might have some neat selections too at their lemon grove location. I know right where KRC in lakeside is also, so I'll make a trip to both places tomorrow morning. May get a bundle of lava rock, and then see if they have some other stuff with neat textures.
If they have plenty of options, it's so cheap I won't mind buying several different aquascapes worth and then what I don't use can sit outside till I can use it lol.
Thanks for the idea!!
