DrTim's Aquatics Reef Waste-Away Sludge Busting Bacteria – For Reef, Nano, Seahorse Aquaria, Fish Tanks, Aquariums – Unclogs, Cleans Gravel Beds, Removes Hidden Wastes – 100% Natural – 16 Oz., 473

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.

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!

I use it all the time in my 28 galllon nano cube salt water tank. It keeps it sparkling clean.

I have an extremely large aquarium of 300 gallons and this is probably one of the most helpful products I have ever had to disintegrate the byproducts left by my huge fish. Yes, I plan on buying this again but I just hope they have it in a larger size.

Not working fast enough, doesn't improved tank quality much

I used this to get rid of a green hair algae outbreak in my tank. In less than two weeks it was gone and I am down to a weekly dose. I am currently using this weekly instead of biopellets to keep the algae at bay. Carbon dosing, biopellets and this are basically all just using bacteria to soak up extra nutrients in the tank. As a side benefit the extra bacteria are food for your corals.

Solved my 1.5 year battle with algae. 120 gallon system with bio-pellet reactor. After manually removing all reachable algae, Dosed instructed amount every other day for about 3 weeks, week 4, all algae gone. Dosed 1/2 directly into bio-pellet reactor intake and other 1/2 of volume into sump love rock are with skimmer off for 3-8 hours depending on my schedule at home. Word of advice- if you need more than 16oz. Bottle for entire duration of treatment, it was far cheaper ordering multiple 16oz bottles vs. the 32/64oz bottle. Larger volume jugs were severely marked up. Be aware, I stopped dosing cold turkey when algae issue was gone, had another outbreak 2 weeks later. May need to dose once a week to keep bacteria levels up. Apex ORP reflected dosing and skimme on/off so at least there is some sort of measurable effect. Did not effect PH.

I have 30 g square tank, no skimmer, filter or cleaning crew. I dont' understand the point of a cleaning crew, since they also make waste? Anyway this product is my cleaning crew. I started to have some red slime on my sand bed. After using this, the next day, it was gone. It does keep the Nitrate and Phosphates down. I like that this product is natural. I have a mandarin fish and need to keep copepods alive. I try to keep everything balanced with good bacteria and whatever lives in my live rocks/ sand. I use Waste away for the last eight month weekly and so far everything works perfectly and my mandarin fish is still alive and eating well.
