It effectively breaks down ammonium and nitrite, utilizing specialized cleaning bacteria. Sera marin bio reefclear, a product of Sera bio technology designed for marine aquariums, works to eliminate ammonium and nitrite with the aid of these beneficial bacteria. The inclusion of mineral volcanic rock helps to eliminate harmful substances, efficiently binds turbidity, and offers a surface for the cleaning bacteria to thrive. This ensures your water is healthy, clear, and biologically active. **Recommended dosage:** Shake well for 10 seconds before applying and then dose right away! A brief, milky cloudiness is expected and indicates the product is working. Depending on the level of impurities in your water, turbidity should clear up within 4 to 24 hours, leaving your water crystal clear. **Dosage for setting up the aquarium:** Use 1 scoop* of Sera marin bio reefclear for every 25 liters of aquarium water. Once ammonium levels are undetectable (for instance, confirmed with the Sera ammonium/ammonia test), it’s safe to introduce your aquatic animals. **Dosage for an established aquarium:** Administer 1 scoop* of Sera marin bio reefclear per 25 liters of aquarium water once a week. **Dosage after water changes or filter cleaning:** Use 1 scoop* of Sera marin bio reefclear for every 25 liters of aquarium water. *1 measuring cup (10 ml) should be filled to the outer line.Shipping Notes

Color: Medium size (ø 5.5")
The toy is best for "non aggressive " chewers.
The seller is fantastic though!! They resolved an issue proactively, without being asked-something you don't see often. That level of integrity sets them apart, and I would absolutely buy from them again.

Do not waste your money
Color: Large size (ø 7.4")
Not for aggressive dogs. I thought this was good for the money it’s not. My dog chewed this up in less than a minute. Not too happy

It's A Beast - But It'll Last Forever
Color: Large size (ø 7.4")
This big orange interactive dog toy does a few things differently—and mostly, it does them right.
First, there are no batteries and no charging required. The internal noise maker is activated by movement, producing little squeaks and quacks that grab a dog’s attention without turning into an electronic science experiment. Second—and more importantly—this thing is built to last. It’s designed to work as both a ball and a tug toy, which means it’s far tougher than the typical interactive balls that get shredded in short order. I fully expect this one to stick around for a long time.
That said, the reaction from my dogs was… mixed. All of them were a bit spooked at first. The sounds made them curious but cautious. My Border Collie was the first to commit and play with it, and she gave it a solid try. After a while, though, interest faded and the toy ended up sitting on the floor largely ignored.
I can get them engaged if I roll it around and hype things up, but the two dogs that usually love tug-of-war haven’t latched onto this one yet. My guess is this toy will shine more outdoors. Once spring rolls around and it’s flying across the yard instead of the living room floor, I suspect it’ll get a lot more action. My dogs tend to burn energy—and enthusiasm—much faster outside.
If you have a heavy chewer that destroys fragile interactive toys (and drains your wallet in the process), this is a very welcome alternative. Considering how quickly $35–$50 electronic balls can meet their end, this toy earns its place in the basket for durability alone.

Good for non chewers
Color: Large size (ø 7.4")
Dog lived it for the 4 minutes before he chewed a large hole in it. Definitely not for heavy chewers.
