AIO Biopellets question

[dcw1sfu]

Any thoughts on mixing the All In One (AIO) biopellets with a regular biopellet? I have almost 1 cup of AIO biopellets in my Aquamax reactor hooked up to a Ehiem 3000 and its now barley tumbling. I had to take a bit of the pellets out to get it to tumble properly as I guess these pellets are alot heavier. I was thinking of taking a bit more of the AIO pellets out and putting a quarter cup or more of Vertex biopellets in with the AIO pellets. Would this cause issues??
