	Aquaculture products
	All-in-one concentrated algal nutrients No mixing, no errors, no contamination, Varicon Aqua's range of concentrated all-in- one culture media make it simple to grow algae to the best yields possible with no fuss. Available as totally soluble powder or concentrated liquid, they contain all nutrients, trace elements and vitamins needed by most common species used in aquaculture or nutriceutical production. Available for F/2, Walnes and our own nannochloropsis/ chlorella formula and as a trace element/ vitamin mix that you can add your own nitrates and phosphates to.
	Algal concentrates By popular request for supplies of concentrated micro-algae we are now holding stocks in the United Kingdom of high quality algal concentrates manufactured by Reed Mariculture Inc. Ideal for rotifer culture due to the high nutritional profile and elimination of shock caused by mismatches in pH and salinity between rotifer water and algae water in traditional culture methods. Gives very high densities of rotifers.
	Algal cultures Varicon Aqua sells plate master cultures of common aquaculture species that can be stored in a cold dark place for months, eliminating the need to continuously sub-culture liquid stock masters. Common strains used in aquaculture are available for immediate delivery. Other strains can be grown to order in any desired volume. Only axenic cultures, sterile nutrients and pure water (for marine organisms we use artificial seawater) are used in the preparation of our cultures. Purchasing large volumes of algae reduces algal production time, avoids shock from dilution in the on-growing environment and improves survival in transit
	Rotifer eggs and live rotifers We supply rotifer resting eggs (Resting Rotifers™) from Florida Aqua Farms and new long-life live rotifers from Reed Mariculture packed in breathable bags that keep for 2-3 weeks in a refrigerator. Picture courtesy of Florida Aqua Farms

	Tubular Bioreactors Tubular bioreactors grow many micro-algae very successfully at between 10 and 20 times the density obtained using bag or fibre glass tank culture methods and in a fraction of the time. There are many literature references to the advantages of this method. Now we make it easy for you to grow algae this way with a proven modular system that starts at a very low cost. We have everything you need to start using or experimenting with this powerful means of algal production. All the materials you need and full instructions are available from us. There are many successful users of our own patented BioFence tubular reactor system. We can also supply and install complete systems. All the information you need is on this site.
