    Seachem Laboratories Seachem Ammonia Alert

    Out of stock

    Seachem Ammonia Alert is an innovative colour-changing device designed to continuously detect and monitor toxic free ammonia in both freshwater and saltwater aquariums. The incredibly accurate sensor changes reversibly from yellow to green to blue, relative to the specific ammonia concentration inside of the tank. Ammonia is the #1 killer of aquarium inhabitants and the convenient device detects less than 0.05 mg/L (ppm) of free ammonia and alerts aquarium owners so that they can take the proper measures to lower the ammonia levels. When free ammonia is not present, the unit will take on a yellow or faint yellow-green colour and is normal for the dry sensor to have a greenish hue to it. There is no water sampling, chemicals or test procedures needed, but the dry sensor may take up to a few days to properly calibrate with the parameters of your aquarium water and will last over a year with accurate readings. In the aquarium, the presence of free ammonia is detectable continuously with a response time of approximately 15 minutes. Response to decreasing ammonia is significantly slower, requiring about 4 hours to go from TOXIC to SAFE on the removal of ammonia. The device is half the size of competitive units, ensuring minimal visual obstruction in the aquarium and lasts over 9 times as long. Properly caring for this unit is essential in maintaining accuracy and reliability over time. The unit can be effectively cleaned with a clean, soft material, yet avoid touching the sensor with fingers as skin oils can damage it. Drying out does not permanently damage the unit, but sensitivity will improve with age as long as the unit does not fully dry out. For the highest level of sensitivity, the device should be read under natural daylight or a daylight simulating light source. Please note that red enhancing light minimizes the intensity of green and blue hues, decreasing the apparent sensitivity of the unit. Some dye medications may discolour the sensor.

The media was created with a specially designed spherical shape to promote ideal hydrodynamics and the increased porosity of the beads helps to improve both the efficiency and the capacity to bring aquarium water to the proper parameters. Despite being effective for both freshwater and saltwater aquariums, Seachem PhosGuard operates better in marine environments where its use is more often required.

  • Seachem Catappa Tea Bags

    Seachem Laboratories Seachem Catappa Tea Bags

    Out of stock

    Tannins, found in substances like Catappa leaves, offer several benefits in aquariums, making them a popular choice among hobbyists. They have plenty of advantages! Tannins help to prevent fungal and bacterial infections in fish and their eggs, reducing the risk of disease in the aquarium. By influencing water chemistry, tannins can slow down or even eliminate algae growth, keeping your aquarium cleaner and reducing maintenance. Tannins can also help manage populations of pest snails and crustaceans, which can otherwise become problematic in aquariums. Fish species that thrive in low pH and soft water conditions will benefit from tannins, often showing more vibrant colours and increased spawning behaviours, and enjoying the shade provided by the leaves. Seachem Catappa Tea Bags bring these benefits in a convenient, mess-free format. They contain whole leaves but are packaged in a small, filter-friendly bag, allowing for easy application and continuous release of tannins into the aquarium without the hassle of dealing with loose leaf debris. Overall, incorporating tannins into your aquarium setup can enhance the health and well-being of your aquatic life while also providing practical benefits for maintenance and habitat enrichment.

    The Seachem DuoPad is a professional quality dual surface, non-scratch algae pad for glass and acrylic aquariums. One side is made with melamine foam, which utilizes micro abrasive technology to effortlessly remove algae from the sides of your aquarium. Melamine foam is an incredibly abrasive cleaner with a microstructure that is as hard as glass, but the open cell structure keeps it flexible, allowing the pad to efficiently remove caked on algae from minuscule surface scratches on the aquarium walls. The second side is textured and durable, making it perfect for scrubbing even the rougher grooves of rocks and driftwood clean. Chemically inert and made without the use of soaps or detergents, Seachem's DuoPad will not leave any negative impact on your aquarium. The white colour makes spotting leftover algae simple, allowing you to keep scrubbing until an area is fully clean.

    Seachem Laboratories Seachem Flourish Iron

    1 in stock

    Seachem Flourish Iron is a highly concentrated (10,000 mg/L) source of ferrous iron gluconate supplement designed for use in planted aquariums. Plants use iron as a way to produce essential chlorophyll, but a lack of iron will result in chlorosis or the yellowing of the younger leaves with short and slender stems. If the deficiency maintains severity and duration, each new leaf that emerges will be lighter in colour than the preceding leaf. Plants are able to better utilize this formula due to the fact that ferrous iron gluconate is already in the ferrous form so plants do not expend additional energy trying to reduce it. Ferric iron is only soluble below a pH of around 5.5, but this will be significantly higher in planted aquariums, rendering this type of iron useless. The ferrous iron found in Seachem Flourish Iron is the preferred iron form as it is an excellent source of carbon and is soluble in water of any pH level, making it more versatile and functional for a variety of different water parameters for planted aquariums. Additionally, the ferrous gluconate found in this formula is better suited to foliar feeding than iron-EDTA, allowing your plants to grow and develop at a quicker rate.
