Meridian Sand 9kg Meridian Sand 9kg

Meridian is an all natural oolitic (spherical or egg shaped) aragonite substrate for all reef and marine aquaria. Meridian is the premium aragonite substrate for the reef aquaria. It's grain size (a fairly uniform 0.25 - 0.50mm) is ideally suited to reef inhabitants and it's chemical composition will assist in stabilizing calcium and alkalinity while preventing large pH declines. Unlike competing "wet" products marketed under the guise of being "live", Meridian is sold dry, thus you pay only for gravel and not for unneeded water. Dry or wet, there are bacteria on every substrate available. If one is concerned with shortening the tank cycle time for a new system, then the use of a product designed for that particular purpose would be more appropriate (such as Seachem's Stability)

Flourite 7kg Flourite 7kg

Flourite is a specially fracted, stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any aquarium environment. Flourite 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. Flourite is not chemically coated or treated and will not alter the pH of the water. One bag is sufficient for about a 5 cm (2 inch) deep bed in a typical 40 L (10 gallon) tank. Recommended use is 1 kg (2 lbs) for approximately each 200 cm2 (31 in2) of tank bottom at a depth of 5 cm (2 in).
