I filled my new 75 last Friday and was prepared to wait 4-6 weeks for the cycle and all that good stuff. I used all dry rock with "live" bagged sand. After doing much reading and talking to people in my area I decided to use Fritz Zyme turbo start 900. I put the required amount in for my volume on Saturday. I put ammonia chloride to get the ammonia to 2 ppm. Tested today and my water looks pretty good. Ammonia-was just trace call it .25, nitrite-1, nitrate-2.5, phosphate-.25. Salinity is 1.025. Going to test in a couple days to see how it looks.
