You can use the bottled bacterial supplement, but it is frankly a waste of money when you have plants like the photos show. You don't want to be stealing ammonia/ammonium from the plants by encouraging nitrification. And, with plants as here, you are not going to see cycling occurring even if it did. The plants grab ammonia/ammonium, and faster than the bacteria can. The only supplement worth using is Tetra's SafeStart, or Dr. Tim's One and Only but this involves ammonia and I do not recommend that, you could easily kill some of the plants. None of the other bacterial products contain the true nitrifying bacteria, they are next to useless.
