As some may know I'm just getting into pond management and I'm reading all I can. I've been reading alot about aeration. I have a system already but am wondering about emergencies as I have read about these situations. I have heard alot about horizontal aeration but can't find any info on products, like Super Horizontal Oxygenator II. I don't have a tractor so that type is out. If anyone has suggestions I'd appreciate it.
