hey guys i have a newbie questions, i have a dwc and it has no problems but i have a ebb and flow 55 gallon resevoir and the i just changed the water out 2 days ago an was gonna transplant plants today but the water stinks bad!!! It has to have algae down there the way it smells, so what do i do? Can i add bleach to kill it or just drain clean and refill, and what can i do to prevent this from happening again? Also the resevior is blue,i could tricked on ebay, is that part of the problem? We wrapped mylar around it to reflect the light but not sure if this was a good idea? 1000 watt mh bulb in a 4by8 feet room about, with 12 pots and one 8 gallon dwc bucket. Thanks sandee
