Answer from CR Aquarium Mr Dennis Tan ( aquatic consultant)
Normally the Bio-Vs alone is more than good to set up new tank. As the amount of bacteria in our Bio-Vs is very high and your tank can be mature very fast. Actually, you can just add water, then Bio-Vs, then fish.... Just that.... Use 1 capsule per 100 litre daily for 3 days. This is more than enough to make your tank mature. You can try it for yourself

Anti Algae is usually used in fresh water tank to prevent algae growth in tank. But now, our Bio-Vs can do same job. So it is best that you use the Bio-Vs in the correct way and it can serve many purpose.
To prevent of algae grown by using Bio-Vs weekly and this problem will not arise.
However, if the algae already there and you need to clear off the problem, we have to produce a new product for such problem. (R&D)
