Will probidio or zeo cycle my tank faster?


New member
Starting a new 500gal, have 300# dead marco rock and 200# live rock (from old tank). Would a bacterial system cycle the tank faster?

Zeo has a start dose same as prodibio. It's called zeostart2. Documentation says it can make a new tank with new water ready for additions within 3 weeks. I haven't used it to cycle a tank so no first hand experience here.

I used the Bioptimum and never had a cycle. I did buy 250 lbs. of live rock though. And did not have much die off at all. I never had an ammonia spike. I was adding corals in two weeks. I don't know if this is normal.
