I have a 20 long with softies and am wondering about flow?? I have one hydor in there now and it's only 245gph I think and I'm getting hair algae and cyano.. I know that's not the cause of it but it doesn't help that I have dead spots so I was wondering what the recommended gph would be for the tank and placement. Thanks
