U can start zeobak and zeostart3 for the first 3 months 50% dosage. The zeolite rock is not necessary. After 3 months u can increase 10% and start spongepower. If u can get some real live Rock then it will help speed up the cycle process.@ycnibrc . I'm just starting out. Fishless cycle with ammonia. 2.5 weeks so far. What should I do to start off with Zeovit? Would like to do hybrid approach. I have RSR650, Bubble mangus curve 7, caribsea life rock and sand. No lights yet as. Looking at Reefi, red sea and other led options. Do i need zeo reactor to start or at all? Should I get lighting setup before starting? Can stones be ran passively in sump? Been reading all the threads, lots to absorb so thanks for your time in helping us out.
