Carefully selected Probiotic Bacteria that greatly help maintain optimal water conditions. The bacteria found in Pro Bio S has been carefully selected to transform phosphate, nitrate, and other organic compounds that will turn into biomass and then can be consumed by corals, or skimmed out of the tank. Another benefit of Pro Bio S is that you will notice less sediments build up on rocks and biomedia. By absorbing and converting organic materials, nitrate, and phosphate, your aquariums water quality will stay perfect with Pro Bio S.

Product Questions

Since my tank is too small for a single drop dose, can I dilute a drop in say... 2 ml water, then dose 1 ml per day? And if so, should I use RO, fresh saltwater or tank water? Alternatively, I am assuming I could dilute in 2 mls water and dose 1, wasting the rest, but I'd rather not waste half the bottle, etc.

While we assume you can, you will want to reach out to Aquaforest to be certain.

Does this also feed sponges ?

Hey Steve,
Thanks for reaching out to us. A key function of PRO BIO S is to transform phosphate and nitrates to a biomass which can be easily removed by the skimmer or consumed by corals, sponges, clams and other organisms

Please let us know if you have any further questions and take care!
