Review: Works against "red slime" (cyanobacteria) is reef tanks - I almost passed over this product because the name made me think it was for fish that were wasting away. Not so! It is for clearing up cyanobacteria ("red slime") from salt water reef tanks. The products that claim to clean the "red stains" stop working after a few months. Bacterial resistance is my guess. So I've been looking at other types of products. This product is not the only "our bacteria will out-eat the red slime" product I've tried, so I was a bit skeptical. But after using it for a couple months (and continuing my weekly scrubbing of the red slime), I find I no longer have to scrub! The corals and other creatures in my tank don't react to it at all, unlike the "red stain removers". Well, that's not completely true. The corals exhibit feeding behavior after I treat the tank. This product doesn't cause my skimmer to over-skim, either. It is not reducing the hairy algae, which would have been nice. But, hey. I'm just happy to be rid of the red slime. The bottle is practically empty now. I expect I'll have to buy another bottle in the future and will gladly do so.
Review: Works for me!!! - Re new and waste away were used to treat my 240 gallon saltwater tank. If you scan the qc bar on the back of bottle it will take you to Dr. Tim's website. The website gives a recommended schedule for treatment. The bottle of re new was used first, the waste away treatment was started next. When waste away was started I also started lights out for the days. I still have another dose of waste away to do tomorrow. Today my lights came on and all I can say is wow, what a difference. I've struggled with the cyano red algae for a way to long. I tried several things and was very frustrated. So far I'm very pleased with the results so far. This tank has been up for 8 years. There is a blue tang that was from an old tank that is ~15 years old. I was ready to throw in the towel. The tank looks so much better. Thanks!
