i would only use lr/ls or raw shrimp, no animals, and DEFINITELY NO BOTTLED PRODUCTS, IMO, they anr not worht the money spent on them and do not do enough of what they claim, and they definitely do not speed the cycle enough to give them honorable mention, i had more problems with these products, and i cycled our 75 in 2 and a half weeks without it, AND had alot less problems with stability
HTH and good luck
