Testing the Waters

In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions.

Your API Test Options

Choose the test method that works best for you. Whether you’re a bit pressed for time, or you prefer to measure your parameters on a more in-depth scale, or you only need to test one or two specific parameters, API has what you need!

Dip and Read

Just dip a 5-in-1 TEST STRIP in your aquarium, swirl twice, and compare to our color chart for fast and accurate results.

The Scientific Approach

For more detailed analysis, use the FRESHWATER MASTER TEST KIT, POND MASTER TEST KIT, SALTWATER MASTER TEST KIT, or REEF MASTER TEST KIT for precise readings of parameters.

Stylish comfort you can wear all day!
Size: 6.5, Color: Chestnut
My wife has been been wearing the UGG Goldenstar Sandals for a few weeks now, and they’ve totally exceeded expectations. These sandals strike the perfect balance between comfort and style, and she’s gotten so many compliments on them! Pros: • Super Comfortable: The cushioned footbed feels like walking on clouds. Perfect for long days on your feet or casual outings. • Lightweight: Unlike some chunky sandals, these are surprisingly light but still feel supportive and well-made. • Adjustable Straps: The Velcro straps make it easy to get the perfect fit, and they’re great for swelling feet after a long day. • Versatile Style: They look great with everything—from jeans and shorts to casual dresses. • High-Quality Materials: Typical UGG quality—durable suede and solid construction. Cons: • Suede Requires Care: The upper is suede, so they’re not ideal for wet conditions and do need a bit of maintenance to keep looking fresh. • Pricey: They’re on the higher end cost-wise, but I’d say the comfort and quality justify the price. I’m really happy with these sandals. They’re a perfect mix of fashion and function, and I’d definitely buy them again in another color!

Best Sandal Ever
There is nothing about these that I don't LOVE. These are so comfortable and look so good. I have 6 pairs in every color. They r my absolute favorite. Run true to size. Listen to Amazon about sizing. They know... I am between size 7 and 7.5 and they recommended 7 and it was a perfect fit. I have not had any issues with the Velcro closure. Amazon has the best prices for UGGS.

Sandals that go with just about everything.
As a lover of everything Ugg, these didn't disappoint. They are some of the most comfortable shoes I have, very lightweight, and go with just about everything. They remind me of the old school Dr. Martens and I had a massive collection of those in high school. I have worn them quite a bit and you can barely tell as they are holding up extremely well.

Cute and comfortable!
Size: 6.5, Color: Chestnut
These are cute and surprisingly comfortable! My arches feel supported and the soles don’t feel as block-like as other platform style sandals! Things to note: The footbed liner is not made of suede and is a little slippery. It’s like a neoprene liner which was unexpected for an Ugg shoe. Also, I only intend to wear these sandals as slides (a la Birkenstocks) so the “adjustable” Velcro strap over the top part of the foot seems useless. It doesn’t snug the top down at all, functionally speaking it is only to wear around the back of the ankle. Maybe this matters to someone thinking they could tighten the top down a bit. The ankle strap is comfortable but could be a bit longer. Overall they are a cute option to the platform Birks that are very uncomfortable imo. Love the options to order half sizes. I’m usually a 6 in Ugg boots but ordered my regular shoe size 6.5 and they fit well. My heel would be at the very end of my sandal if I sized down. True to size. Keeping and will order in another color!
