I am upgrading my tank from 10g to 40b. I will have everything done to stat cycle after Thanksgiving weekend. I put a bag of biopellets on the sand bed on one side of my current tank and a 8X8X1 block of Marinepure against the glass on the other side so that I can have cycled media to hopefully speed up cycle. I just wanted to know if you guys think it would be better to place in DT or to go ahead and put in sump. I am going to be using the 10g as a quarantine so hoping that this will in fact speed up my cycle. Thank you in advance for any info.
