Description
With Live bacteria included !
AF Bio Sand is a natural white sand derived from the highest quality deposits. It is free of any contaminants and its calcium carbonate content helps to stabilize water chemistry.
The latest technology in AF Bio Sand significantly accelerates the maturation process of an aquarium, and allows faster livestock addition in a newly set up tank. The bottles included contain laboratory isolated strains of nitrifying bacteria and a nourishment, facilitating their development and multiplication.
The specialist formula of the product guarantees closing of the nitrogen cycle and elimination of harmful chemical compounds much faster than if using traditional substrates. The extremely easy usage of AF Bio Sand allows instant preparation of sand for use in the aquarium. Due to the extremely wide range of application, AF Bio Sand will also work perfectly in mature tanks as a substrate supplement. Sand granulation is 0.5-1.5 mm.
Instructions For Use
Sand residue emerges during the transport and it’s perfectly safe for your aquarium, though, in order to avoid water turbidity we strongly advise to rinse the sand in RODI water before use. Pour the contents of both bottles into 3 liters of saltwater, mix thoroughly, add to the sand bag and leave for 24 hours. In order to allow bacteria multiplication, do not close the bag.
We do not recommend storage in cool places, as it significantly increases the time of bacterial multiplication. The optimal sand maturation temperature is around 25-28°C (77-82°F). After 24 hours the sand is ready for use in the aquarium. When using in a functioning aquarium, please add sand gradually into the tank (small amounts day by day), monitor parameter changes and observe the corals.
Product for aquarium use only. Not suitable for human consumption. Keep away from children.
Aquaforest Bio Sand for new SG marine setups
Choosing a substrate sets the tone for a marine tank, and Bio Sand takes the gamble out of starting from dry. This aragonite-based sand ships with bottled live nitrifying bacteria, so instead of waiting weeks for a sterile bed to colonise, you are seeding the substrate from day one. The calcium carbonate content also helps buffer water chemistry, which is handy in a closed reef where parameters drift if left unattended.
For Singapore reefers, the bagged 7.5kg and 10kg sizes are easy to plan around when you are working out depth for a tank that fits an HDB or condo footprint. We usually advise a shallow-to-moderate bed unless you are deliberately running a deep sand bed for denitrification. Rinse expectations aside, this is designed to go in with minimal fuss, and the included bacteria bottles give your maturation a genuine head start in our warm climate.
