Hi Sunny... In using MB7, maybe you could help shed some light on the dosage, the instructions are a little confusing. Bottle reads:
Stable, Low-nutrient Systems: To maintain a low concentration of available nutrients in all marine and freshwater aquaria, 5 ml (1 capful) of MicroBacter7 per 50 US-gallons (189.3 L) [˜2 drops per gallon (3.8 L)] of aquarium water no more than once each week; alternately, add 1 drop per 50 US-gallons daily (or 1 drop per 25 US-gallons every other day). Turn protein skimming and UV-sterilization off for a period of 4 hours following addition to aquaria. Dosage may be adjusted according to perceived benefit to aquarium, however it is recommended that the dosage not exceed 1 drop per 10 US-gallons per day. With time, hobbyists may determine that decreasing the dosage and/or dosing frequency by up to 50% sufficiently maintains a low-nutrient environment. During changes in biological filtration or when increasing the aquarium bioload, dose 1 drop per 25 US-gallons daily for one week, then resume “low-nutrient†dosage.
So for (rounded off for simplicity) a 150 gallon system, should I add:
A) 15ml (3 cap fulls) once a week? ( I would guess this would be in excess of 200 drops)
B) 75 drops (2 drops per gallon) once a week?
and then the kicker on the label above: dosage is not to exceed 1 drop per 10 gallons per day? = 15 drops.
What am I reading wrong?
I have nil nutrients, and the tank is stable (using vodka) steady 1.8mL per day, but want to begin using MB7 (I have it, but don't know what levels to start)
Any help would be appreciated.
