    Something new for our cycle referencing and proofs thread. That is a low surface area setup. No sand. No rock quarantine tank using an external filter with siporax as the surface area media. Here's how I think that thread relates to ours

    Single parameter cycling. What does ammonia do after the known submersion period has passed vs other params, and has that mattered on previous pages, and do params other than ammonia matter here?


    *in our thread, we never assess a cycle off what the final wastewater numbers are, we change the water out and digest test at a custom level using salifert testing, relative to a tanks surface area varistion from norm. We test the opposite of metabolite laden wastewater, we test the clean palette to really see where a cycle has occurred or not

    We don't use API either

    Do we have to digest test at the stated two ppm levels in a tank using very low comparative surface area? No rocks or sand is mighty different than most. Worth considering.


    Another really interesting feature of this particular tank was that the sole nitrifying surface area was in the back chamber, in a baggie, not the same as display tank constant-contact ammonia water with live rocks and sand. For this setup that seems to be misbehaving above, their tank water swirls around up front a lot before portions of it reach the back, for nitrification, but we're testing and making assessments only off the front portions.


    All cycles behave the same relative to boosts and surface area at hand, in this case to get a classic-behaving cycle, we had to account for special arrangements. His surface area was active within 30 compared to normal setups. I suggested moving the siporax to another container and testing there, in closer confines.

    Blast, I wish I'd found this post before I dosed my live, group B rock with ammonia. Can I suggest that this be pinned? The discussion on the different types of live rock (group A/B) vs dry rock and how best to cycle was very beneficial to this 'newbie'.

    This, I wasted a lot of my red sea nitrate/nitrite test kit(and time) testing for nitrite while cycling my first few tanks...
