Questions & Answers

10 Customer Questions

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.

Will this product work along with the Stress Coat?
Answer by ChewyNov 03, 2022
The API Stress Coat and the API Turtle Sludge Destroyer are compatible and can be used in the same aquarium concurrently. Make sure when using any new water that it is dechlorinated first (with Stress Coat or other dechlorinator) before use of any bacterial product (like the Sludge Destroyer) to make sure the bacteria is not exposed to chlorine or chloramines in the tap water.

Will my turtle die if I add to much sludge remover?
Answer by ChewyJul 24, 2022
Overdosing of sludge remover will not be harmful to the turtle.

I wish I had known about this magic liquid potion 10 years ago!! No more thick, dense and sludgy water! I can actually see our turtle again! I've been using it for 3 months. Excellent product! Our turtle looks so healthy and happy. If I could give it bonus stars, there would be 5 more.

Sludge destroyer

I didn't realize what a good job that sludge destroyer does. It's wonderful. I will be adding this to my auto ship. I did a water change for my turtle tank. All of the sludge was caught up in the filter. Very easy to do water change.

Great stuff

Works great. I have 3 painted turtles and this made my tank water look and smell SO much better within about 30 minutes

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.

it works but not for long

I have to clean my turtle's tank once a week and the water is bad after about 3 days..Bottle says every 2 weeks use product and clean water once a month I make it nowhere near there.

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.
