I was wondering if lava rocks were available locally? Mr. Google sent me to Lazada, which is cool but would prefer to not wait on delivery if possible, if not no worries. Finally going to get a small aquaponics set-up going. Will be plumbing and wiring things in this week...already have the power supplies, pumps, aerators, etc. Will be looking at a smallish solar set-up as well, prefer to go solar on a daily basis and using AC as my back up. Will go by Polaris tomorrow to see check things out...any other recomendations would always be appreciated on sourcing things out. Thanks! Shawn
