Aqua-Pics Bacta-Boost D 25g — Dry starter bacteria for a single new aquarium
Not every aquarist wants a bottle of liquid taking up fridge or cupboard space for a bacteria supplement used a handful of times. Aqua-Pics Bacta-Boost D 25g (SKU: 724822) is Aqua-Pics’ dry, super-concentrated bio-starter, described by the maker as a 100% natural ammonia and nitrite reducer that supplies the beneficial microbes and enzymes needed to break down fish waste and convert toxic ammonia and nitrite into nitrate. It works in both fresh and salt water, and the 25 g pack is sized to run one new aquarium through a full starter course rather than stocking a fish room.
Aqua-Pics directs a first dose of one level teaspoon, about 3 g, per 100 to 300 L of water, then twice weekly for 4 to 8 weeks a half teaspoon, about 1.5 g, per 100 to 300 L, repeating the maintenance dose with each water change afterwards. Aquarium plants and regular water changes are left to manage the nitrate produced once ammonia and nitrite are processed, the normal arrangement for a biological starter rather than a complete water conditioner. A full course for one tank, the initial 3 g dose plus roughly eight to sixteen twice-weekly 1.5 g doses over 4 to 8 weeks, uses somewhere around 15 to 27 g, so the 25 g pack covers one tank’s complete starter course with little left over.
Usage & Application
When to Use
- New aquarium set-ups: The first dose seeds the biofilter before or as fish are added.

- With water changes: Repeat the maintenance dose each time water is changed.
- Fresh or marine tanks: One dry formula suits either water type.
Dosing & Administration Guide
- First dose: 1 level teaspoon (about 3 g) per 100 to 300 L of water.
- Twice-weekly maintenance: 1/2 teaspoon (about 1.5 g) per 100 to 300 L, for 4 to 8 weeks.
- Repeat with changes: Continue the maintenance dose at each water change after the course.
