About This

  • NOTHING LIKE OLD SCHOOL: The Clear-Free Premium Under Gravel Filter is air driven and utilizes an Air Pump (not included) to cycle crystal clear water throughout your aquarium, while keeping a crisp and neat look inside. This means there’s less “moving parts,” making for simplistic and easy maintenance. This filter is suitable for most 40 – 55 gallon aquariums.
  • BIOLOGICAL, CHEMICAL, AND PHYSICAL FILTRATION: As air is pushed through the Air Stones and rises through the Lift Tubes, water is gently suctioned through gravel and the filter plates, allowing both air and water to pass through the Filt-a-Carb Activated Carbon Cartridges. When water continues to be drawn through, anaerobic bacteria collects and colonizes within the gravel and filter plates.
  • ALSO AERATES YOUR TANK: Since the Clear-Free Premium Under Gravel Filter is air driven through the use of Air Stones and an Air Pump (not included), it also aerates your tank. In essence, your aquarium is being filtered and aerated at the same time, though the same system. It’s a filter and bubbler in 1.
  • ITEMS INCLUDED: The Clear-Free Premium Under Gravel Filter includes 4 Filter Plates, 4 Adjustable Lift Tubes, 4 Straight Airline Tubes, 9 Filter Plate Connecters, and 4 Replaceable Filt-a-Carb Activated Carbon Media Cartridges.
  • MEASUREMENTS: Each Filter Plate Separately = 11.25” (W) x 11.25” (D) / Filter Plates Together = 45” (W) x 11.25” (D) / Each Lift Tube at Filter Plate Base = 13.25” – 16.5”

Good Everyday Mascara
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
I’ve been using the Maybelline Lash Sensational Sky High Washable Mascara for a couple of weeks now, and overall I’m really impressed. The biggest standout is the length. It genuinely makes my lashes look noticeably longer without needing multiple coats. The flexible brush does a great job grabbing even the smaller lashes, and I didn’t have much issue with clumping as long as I applied it carefully. It also holds a curl better than I expected for a washable formula, which is a big plus. Another thing I appreciate is how lightweight it feels. My lashes don’t get that heavy, stiff feeling some volumizing mascaras can cause. It’s also easy to remove at the end of the day, which makes it great for everyday use. That said, it’s not perfect. While it does add some volume, if you’re looking for a very bold, thick lash look, you might find it a bit lacking. I also noticed a tiny bit of smudging under my eyes after a long day, though nothing too extreme. Overall, this is a great mascara for length and a more defined, lifted look. I’d definitely repurchase, especially for daily wear, but I’d pair it with something more volumizing for special occasions.

Last long
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
Absolutely love this Maybelline mascara! It makes my lashes look longer, fuller, and more defined without clumping. The formula lasts all day and doesn’t smudge easily. It’s affordable, easy to apply, and gives such a beautiful lash look.”

A perfect natural glam mascara
Color: PLUM TWILIGHT, Size: 0.24 Fl Oz (Pack of 1)
I have been searching for my ultimate, every day mascara for at least 10 years & I actually tried this one about 4 or 5 years ago (not in this shade though) and I remember it being a strong like at the time but not “the one”. Buuut this might be the one. Went on smoothly with minimal clumping. Elongated and curved my lashes upwards without using an eyelash curler. Held up for 9 hours in humid, sticky conditions and is still going strong. No flaking, smudging or transfer. I do wish the brush was different, or had longer bristles at least, but not enough to dock a star over. The plum shade is gorgeous and veers toward black in some lighting but has just enough color to enhance the eyes. It didn’t add a ton of volume, but enough to be noticeable and I actually prefer that because I have sensory issues with my eyes and that is why I sadly can’t do falsies. All in all, this is a 5 star, every day, natural glam mascara and now I want to try the green.
