Our softner pillow is perfect for Bettas and other soft water fish such as Discus and Killis. Simply add the pillow to your filter and it will immediately get to work. The beads within the pillow remove magnesium and calcium ions, as well as heavy metals from the water to lower the GH and maintain it. The softener pillow can be recharged by soaking it in a salt solution. This is a must for any betta keeper who lives in a hard water region, we use it ourselves with all our wild Betta and blackwater fish.
Our high-density biomechanical aquarium sponge pads are constructed with a course top layer followed by a dense layer of polyester fibres.

Our Castle Dawn Aquatics biomechanical aquarium filter sponge is triple-layered, using coconut and bamboo carbon as the outer layers. Bamboo carbon absorbs harmful chemicals as well as releases essential minerals into the water such as potassium, sodium, calcium, and iron. Coconut carbon is 50% more effective at absorbing organic and inorganic chemicals than any other activated carbon. With the carbon layers, the sponge is extremely effective at removing discolouration from the water caused by algae and tannins, keeping your water crystal clear.
INTELLISPONGE smart filter media is infused with natural components to provide optimum biological and chemical filtration.
Each colour adds something essential to the aquarium, brown which is infused with volcanic soil is rich in essential elements and can help Soften the water.

Our high-quality crushed coral filter media is ethically sourced and is collected from the sea bed by hand and not by net dragging, which is extremely detrimental to the sea bed and existing live reefs.
Crushed coral is a natural PH buffer stabilizing a pH of 8.2-8.3 making it perfect for marine and African rift lake cichlids.
Due to its porous nature, crushed coral has a large surface area creating an ideal environment for nitrifying bacteria and will naturally raise the GH and KH of the aquarium water.
Our high-quality lava rock filter media is hand-selected and is rich in essential elements including magnesium, calcium, iron potassium and manganese, making it ideal for shrimp aquariums.

Peat filter media not only benefits the inhabitants of the aquarium but also aquatic plants. The released Humic substances from our peat filter media bind and immobilises heavy metals, increasing the availability of important nutrients for aquatic plants such as iron, and allowing phosphorus and nitrogen to be more efficiently absorbed.
Not suited for Cardinal Sulawesi shrimp(Caridina dennerli).
Our Kaldnes media is made from 100% virgin Polyethylene. Kaldnes media is suited for fluidized filters where the media is kept in constant movement. The media is constantly crashing into each other causing old bacteria on the outside to fall away allowing more surface area for healthier bacteria to colonize. It is this process that removes harmful ammonia and nitrite from the water. Fluidized Kaldnes media provides the maximum active surface area for the bacteria to colonise, more than other types of static media.
Our high-density durable premium aquarium filter sponge pads are constructed with several layers of polyester fibres capturing large and fine particles. The filter pads are up to 5cm thick and can be cut to size to suit any aquarium filter or sump. Our aquarium filter sponge pads are fluorescent dye-free which is commonly used to enhance the whiteness of polyester fibres.
