Seachem Onyx Sand

$27.80 – $43.70

  • Premium natural sand for the planted aquarium
  • Good for the life of the aquarium
  • Supports optimal KH levels for freshwater planted aquariums
  • Rich in carbonates

Description

Onyx Sand™ is a naturally dark gray sand that perfectly complements and enhances the appearance of any aquarium. It provides not only iron and other minerals but supports optimal KH levels for freshwater planted aquariums. Being carbonate rich, Onyx Sand™ provides an advantage to any plants able to utilize bicarbonates. Although ideally suited to planted aquaria, it may be used in any aquarium environment. Onyx Sand™ is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Onyx Sand™ is not chemically coated or treated but does have a slight buffering capacity that may raise pH by 0.1 – 0.5 pH units (depending on source water characteristics). Onyx Sand™ is good for the life of the aquarium and need not be replaced.

To determine the number of bags required for your aquarium, please note that each bag (7 kg, 15.4 lbs) occupies a volume of approximately 4,250 cm3 (260 cu. in.). To determine your desired volume multiply tank width by length by desired depth. This bag is sufficient for about a 3.5 cm (1.5 inch) deep bed in a typical 40 L (10 US gallon) tank.

Directions

Although it is pre-washed, because Onyx Sand™ is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust.

TIPS: When adding water to aquarium, fill slowly to avoid disturbing Onyx Sand™ bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss). Clarity™ clearing.

Seachem Pearl Beach

$30.60 – $54.40
  • Natural aragonite sand for all types of marine, reef, and tropical aquaria
  • Assists in stabilising calcium and alkalinity
  • Helps prevent large pH declines
  • Pure dry sand (no water fillers)
Seachem Pearl Beach is natural, aragonite sand for marine, reef and tropical aquaria. The oceanic substrate helps to stabilise calcium and alkalinity in your aquarium, and prevents large pH declines.

Advantages

Seachem Pearl Beach is all natural aragonite sand ideal as substrate for all reef and marine aquaria. This sand is particularly suitable for reef organisms, while its chemical composition helps to stabilise calcium and alkalinity, thereby preventing large pH declines.

Dry vs Wet Gravels

Unlike competing wet gravels, each bag of Seachem Pearl Beach contains pure sand gravel without water as filler. Some wet gravels are marketed as containing living, microscopic animals when in fact they only contain common bacteria. Dry or wet, bacteria exists naturally in every substrate. If one is concerned with shortening the aquarium cycle time for a new system, then the use of a product designed for that particular purpose would be more appropriate (such as Seachem Stability).

To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity to accelerate clearing.
