MICROBE-LIFT Gravel & Substrate Cleaner for Saltwater Aquarium and Freshwater Tanks, Tank Cleaner and Aquarium Water Conditioner, Clarifies Water, Reduces Sludge, Aquarium Supplies, 8 Ounces (GSC08)

Works well for my 29 G tank ,I have a planted coal slag tank and this keeps my the algae down and the water clean

It’s dark colored so your water will turn brownish when you put this in the tank, but it clears quickly. After using this for a while I can say that my water has never been so clear and my artificial plants have never been so clean. Extremely pleased and I only use the lower recommended dose on the bottle every two weeks.

Fast Easy shipping - worked first time I used it. Makes tank a little murky at first but then bammm cleans it right up. Filters do the rest.

Works gret

I had purchased this recently as previously I was using W.O.W. from Petsolutions and that product has been dis-continued. I wish I knew about this before. Microbe-lift gravel cleaner works great. As other reviewers have stated, when you first put this in your tank, it looks like ink and will turn your water very dark. This lasted for 4 days the first time I used it and then it cleared up quicker the second time and only lasts for 3 days. What a change though. This cleaned my substrate and it is very clear now and the water looks crystal clear. I have a 46 gallon tank but I do have great filtration with two Rena Canister XP filters. I would say the better your filtration, the faster the water will clear but this stuff does work. If you have a dirty tank or substrate, I would highly recommend Microbe-lift Gravel Cleaner. If you have that problem, just have some patience and this will work. A must buy for Aquarium maintenance.

This product is absolutely terrible and darkened my entire tank, including my plants

I have a 65 gal, 2 - 45 gals, a 20 gal, and my cats 3 gallon Betta tank, all freshwater. I must do most things right as I have 2 - 21 year old Amored Catfish (Bonnie & Clyde), and my Coy Angel fish on average are up to 9 yrs old. I began having a few different issues and the brand I've used for years stopped working. Out of the blue, I decided to a new brand, reading the information for the Microbe-Lift, I decided to try this brand. ALL 3 work great! I'm so impressed and I have much more time to enjoy my fish because the weekly maintenance doses keep all of my tanks crystal clear. I'm very happy to recommend the Microbe-Lift brand to EVERYONE that has any size and type of aquarium. I can always tell when all of my fish are happy because the Catfish, who are basically nocturnal, swim all over the tank during the day. I will continue to use Microbe-Lift as long as I have a running aquarium. Do yourself a big favor and get this brand!😃

Haven't used yet but my fiance and I were reading instructions and this instruction broke our brains.
