Safe for shrimp/snails??

Answer by Chewy • Mar 19, 2022
This water clarifier is safe for shrimps and snails.

Have 120 gallons aquarium. How many drops do l need?

Answer by Chewy • Jan 21, 2019
It is recommended to use 2-4 drops per gallon. A 100 gallon aquarium would require approximately 2 teaspoons of the clarifier.

is there any kind of fish (ex mollies) that this should not be used on? or corys? they seem to have an adverse reaction when I add it to the tank??? I've lost several mollies & wondering if this might be the cause?

Answer by Chewy • Feb 17, 2021
This product should only be used in fresh water and cichlid aquariums.

do i need to rinse my filter pad out after using this product?

Answer by Chewy • Feb 18, 2023
After using this clarifier you do not have to clean your filter pad out.

Worked for a day

Worked for one day on my 5 gallon (only shrimp), barely worked on my 20 at all and 2 of my fish died so I ended up doing a water change on that one. Unfortunately

Worked for one day on my 5 gallon (only shrimp), barely worked on my 20 at all and 2 of my fish died so I ended up doing a water change on that one. Unfortunately I bought 2 bottles because I read online it worked so well and wanted to have an extra on hand it case it ever happened again. Would not recommend.

Not for tanks with snails

I ended up not using this product because it is supposedly harmful to snails... which I have several.

Been using for over a decade

Acurel always clears up any haziness in the water . I usually use after changing out a filter.

I wouldn’t use anything else to make my 55 gallon aquarium crystal clear. Chewy has the best price on it to. Highly recommend! I’ve used it for years. Nothing else

My aquarium fix from Chewy

I needed this product and couldn't find it anywhere. Also couldn't find the fish food I wanted for our fish, Chewy had it. AcurelF bottle was wrapped in another

I needed this product and couldn't find it anywhere. Also couldn't find the fish food I wanted for our fish, Chewy had it. AcurelF bottle was wrapped in another bag , just in case of leakage. I appreciate that. I really appreciate that it got to me quick so I can fix what's wrong with our aquarium fish water.

It really works

I have 33 long aquarium with real plants, 2 30 gal. Filters, and 1 sponge filter. The water was always crystal clear. Then for no apparent reason it became cloudy

I have 33 long aquarium with real plants, 2 30 gal. Filters, and 1 sponge filter. The water was always crystal clear. Then for no apparent reason it became cloudy. I chose this remedy based on many positive reviews. I added only half of the recommended dose just to be cautious. It took 2 days to the water to become crystal clear. And all the fish are doing fine. Including before and after photos.
