Aqua-Pics Bacta-Boost D 50g — Dry starter bacteria with margin for a second treatment
A tank cycle rarely goes exactly to plan, and running out of starter bacteria halfway through the maintenance weeks means a gap in dosing right when the filter needs it most. Aqua-Pics Bacta-Boost D 50g (SKU: 724823) is the mid-size pack of Aqua-Pics’ dry bio-starter, a 100% natural ammonia and nitrite reducer that the maker describes as super concentrated, supplying the beneficial microbes and enzymes that break down fish waste and convert ammonia and nitrite into nitrate. It suits fresh and salt water, and 50 g gives enough margin to run one tank’s full course with product left over, or to cycle a second tank later.
Dosing starts with one level teaspoon, about 3 g, per 100 to 300 L on the first day, then drops to a half teaspoon, about 1.5 g, per 100 to 300 L twice weekly for 4 to 8 weeks, with the maintenance dose repeated at each subsequent water change. Nitrate from the processed ammonia and nitrite is handled the usual way, by plants and water changes, rather than by the starter itself. A single full course for one tank uses roughly 15 to 27 g across the initial dose and the twice-weekly maintenance doses, so a 50 g pack stretches to about two complete courses, useful for restarting a tank after a disruption or keeping a second system on the same schedule.
