imo if your just starting to cycle, running the bio pellets might hinder your progress because during the nitrogen cycle, the last stage is nitrates. Which we all know of. Now from my understanding, running biopellets is supposed to enhance the bioload of anerobic and aerobic bacteria to reduce nitrate and phosphates levels. You need both for it work properly. So running it now may not be the best option for you... I would let it run it's natural course and later on after 6 months start to run it. Jmo of course.
Patience is the key my friend.....
