Does this product work well with cleaning water?
Answer by ChewyAug 03, 2017
This product creates a cleaner, healthier environment and reduces aquarium maintenance.

Is it safe for fish
Answer by ChewyFeb 28, 2021
The Turtle Sludge Destroyer is safe for all aquatic pets including turtles, frogs, newt, fish, etc. It contains only the live bacteria that break down the sludge and these bacteria are completely nonpathogenic and completely safe for all life.

This says it can be used for aquatic frogs, what about bullfrogs? I have an African bullfrog who is in his water almost 24/7
Answer by ChewyMar 28, 2022
This can be used with Bullfrogs as well.

Does this help with algae
Answer by ChewyApr 13, 2021

Great product

I am using the sludge destroyer to keep water clear in two tanks with medium sized water turtles. Regular water clarifier wasn't getting the job done, even with good filtration. This product is a simple formulation that keeps the tanks remarkably clear when used every couple of weeks, coupled with good pumps and clearning the filtration every 6-7 days.

Worked better than I anticipated

I only added this to my tank once but after almost a year of having issues with a cloudy tank within a week after cleaning and/or changing the water completely, my tank has cleared up nicely after using this just once. I'm honestly impressed.

Wonderful Product

This sludge destroyer works like a charm! After I pour it in, it only takes an hour or so to see the results.

Works well

I have a musk turtle and this sludge destroyer really helped make sure the debris goes through the filter.

Only product that is effective

I have cared for my two turtles for 45 years, been through countless pumps, and multiple aquaria. The vast majority of products simply do nothing or make things worse. Often the chemicals create a scum of their own. This product works best when the water has waste in it. I do not use it as instructed when the water is clean or filters are new. But when the water begins to age I begin to add this and the water clears quickly and waste/aroma quickly dissipates. There is very little I don’t know about running turtle aquaria after 45 years with the same two turtles. This is good stuff but I suggest using it only as a water/filter life extension- not as a first thing. The photo is of the water after one day. The water is one month old and was getting aromatic and cloudy prior to the addition of the product.

Gets the Scum Out of the Tank

I’ve been using this product along with Reptisafe water conditioner in the external canister filter for my turtle’s tank since 2016. It is very good for getting the accumulated scum off the sides and bottom of the aquarium.

Sludge destroyer destroyed my tank water

My turtle is very messy. I tried sludge destroyer but it just made his tank water cloudy and smelly despite having three filters running and resulted in my turtle trying to desperately escape within a few hours of putting it in. Luckily I had another vacant, clean tank I could put him in while cleaning his tank out. I have since found another product that is excellent as it adds, and keeps, the good bacteria in while keeping the water clear and smell-free until the next water change.

Smell Be Gone

My turtles 20 Gallon tank would always turn clowdy and begin to smell two or three days after a water change. After I bought it and used it to treat my tank. My water is clean and is barely clowdy at all. Thanks!
