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.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

Love these flats!
Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!

LOVE LOVE.
Size: 7.5 Wide, Color: Beige
I love these shoes so much I had to write a review. So comfortable. Cushioned. Fits perfectly especially if you are more on the wide side. They are soft. Flexible. Easy slip ons you can walk around in all day. I want to try more colors.
