I just wanted to share my experience with everyone. I had a very persistent Bacteria Bloom that had been going strong for about 2 weeks. I was reading everything online and didn't want to go the UV route, but it was becoming obvious that this wasn't going to just go away. My tank was newly set up, dead sand, dead rock, cycled with One and Only Nitrifying Bacteria with clown fish (300 gal system), after cycle added CUC and more fish that's when I got bacteria bloom, ammonia, nitrite, everything fine, funny note it ate up my Alk i'm assuming for carbon. I read on here that Dr. Tim recommends his Waste Away product for Bacteria Blooms. I reached out to him through his website, and got a response that yes they recommend Waste Away for Bacteria Blooms. I didn't get a response to how bacteria fixes bacteria, or how much product to add, whether to turn skimmer off or anything else. Well the Waste Away showed up and I was desperate so I went ahead and added it. I just did a full dose for my tank, they say not to fully dose for fear of bacteria bloom, but I wasn't afraid of that since I already had one. I turned my skimmer off for about an hour, then turned it back on. Sometime during the night it freaked out and was overflowing when I woke up. I cleaned it and started the skimmer again. After 24 hours it was definitely clearing After 48 hours it was clear, I could see larger white spots in the water but so much clearer then it was. Was producing large amounts of good skimmate at that point. After 4 days I still have some white spots floating around so I can't call it crystal clear yet, but in my book success for sure. I will do a water change and a second dose once i'm 7 days away from the first dose. Anyone who is searching and researching about persistent nasty bacteria blooms I can say Waste Away absolutely worked in my tank!! Thanks Dr. Tim.
