Wow sorry seem to have dropped this thread somehow negative I have set it up in my shop to make sure everything was there but then took it down I suspect I hope brown goo will not infect the RDWC I ran bubble buckets for awhile never had any issue matter a fact I didn't even know what the brown algae H and others spoke of looked like so I had to look online I want to redo my shed so I can give the system a try
