Prodibio BioDigest is a concentrated blend of live, multi-strain bacteria that jump-starts and maintains biological filtration in freshwater and marine / reef aquariums. Each single-dose glass vial delivers bacteria that work together to break down waste, keep ammonia and nitrite under control and bring nitrates and phosphates down — the root cause of most nuisance algae.
Why use BioDigest?
- Cycle a new tank faster — establishes biological filtration in freshly set-up freshwater and saltwater aquariums.
- Complete nitrogen cycle — converts ammonia to nitrite, nitrite to nitrate, and nitrate to harmless nitrogen gas.
- Lower nitrates and phosphates — for cleaner water and healthier fish, corals and plants.
- Helps prevent algae — including hair algae and cyanobacteria (red slime).
- Digests organic waste — heterotrophic strains break down fish waste, uneaten food and detritus.
- Multi-strain formula — selected Nitrosomonas, Nitrobacter and Bacillus strains that work in synergy.
- Single-dose vials — no measuring, no guesswork: one vial, one dose.
Which pack should I buy?
At the standard dose of one vial every 15 days for one aquarium:
- 6 vials — about 3 months of treatment. Great to try it or to cycle a new tank.
- 12 vials — about 6 months of treatment.
- 30 vials — about 15 months of treatment. Best value for committed reef and planted-tank keepers.
How to use
- Shake the vial to mix the contents.
- Place the cap on one tip of the vial and press gently with your thumb to snap it open.
- Turn the vial over just above the water, snap the other tip and pour the contents into a high-flow area of the aquarium or sump.
- Repeat every 15 days.
Tip: to speed things up (for example while cycling), dose more often — don't pour in larger doses at once.
Dosage
1 vial (1 mL) every 15 days. Prodibio rates each vial for aquariums up to 1000 litres (250 gallons).
Best results: pair with Prodibio Bioptim
