Easy-Life Bio-Exit Blue 1ltr — Litre bottle of cyanobacteria treatment for large freshwater aquariums and repeat courses
In a 400 or 500 litre planted display, a cyanobacteria outbreak covers metres of substrate, and a small bottle will not stretch to a full course. Easy-Life Bio-Exit Blue 1ltr (SKU: 725129) is the one-litre size of Easy-Life’s treatment for blue-green algae in freshwater aquariums, made by Easy Life International in Duiven, the Netherlands. Rather than poisoning the cyanobacteria, it encourages the heterotrophic soil bacteria that break down animal waste, and Easy-Life explains that restoring that microbiological balance in the substrate takes away the conditions cyanobacteria exploit. Used as directed, it is described as harmless to fish and plants. At 100 doses of 10 mL, the bottle runs a complete course on up to 2,000 L of water.
Each course uses two doses a week apart: 10 mL per 40 L on day one, the same again on day seven, and a water change on day fourteen. Nothing should be changed in between, and activated carbon is removed from the filter before starting so it does not take up the treatment. Shake the bottle before dosing and stay with the stated amount rather than adding extra. When cyanobacteria linger or regrow, Easy-Life allows the course to be repeated. Worked out for a large tank, a 400 L aquarium takes 100 mL per dose and 200 mL per course, so this litre covers five full courses; a 1,000 L system needs 250 mL a dose. That makes this size the economical choice for big displays, shops treating several systems and keepers who expect to repeat the course.
