Economies both in budget and scale As more countries strive to enter into aquaculture on a shoestring budget, John's "Small is beautiful" approach to algal production is a refreshing challenge to the megalithic tank systems still generally favoured in the USA. The difference being that running and capital costs are considerably less. Algal quality is consistently high with cell densities of 4000 cells/l. The company offers tailor made systems for any environment indoor or out using artificial or natural daylight. The practical designs are trouble free in operation with capacities from 2 to more than 20 cubic metes per day.
