Description

API pH Up, 16 OZAPI pH UP pH adjuster elevates the pH levels in your aquarium, helping to create a more alkaline environment when levels dip too low. pH measures the acidity or alkalinity of water, with a neutral value of 7. 0; values above 7. 0 indicate alkalinity, while values below 7. 0 indicate acidity. Since various fish species require specific pH levels to thrive, it's crucial to regularly test your water to ensure that pH levels are within the desired range.

API® pH UP pH adjuster elevates the pH levels in your aquarium, helping to create a more alkaline environment when levels dip too low. pH measures the acidity or alkalinity of water, with a neutral value of 7.0; values above 7.0 indicate alkalinity, while values below 7.0 indicate acidity.

Since various fish species require specific pH levels to thrive, it's crucial to regularly test your water to ensure that pH levels are within the desired range. The pH UP pH adjuster acts quickly, is clear, simple to apply, and will not cloud your aquarium water. Additionally, being free of phosphates and nitrates, it will not promote algae growth.

Use an API pH TEST KIT to measure the pH of your aquarium water. To increase pH, add 1 ml for every 10 gallons of aquarium water.

Before administering another dose of pH UP pH adjuster, make sure to take another pH measurement.

Some fish may react sensitively to pH changes exceeding 0.2 within a 24-hour timeframe, so any adjustments of this scale should be approached with caution.

Best mascara I've tried!
Color: VERY BLACK, Size: 0.24 Fl Oz (Pack of 1)
This is hands down my favorite mascara! It gives amazing length and volume without feeling heavy or clumpy. My lashes look so much longer, and it lasts really well throughout the day. I keep coming back to this one because it works better than many more expensive mascaras I’ve tried!

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.

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.
