we can find links that show nitrifiers coming out of tap water and into the water we drink. talk about a place one would typically say you can't find nitrifiers...check local water supply colony counts from the w treatment lab avail to most cities...this is a complex including nitrifiers. How much raw ammonia do you detect in your tap water? Me, zero yet we have no sterile tap, hmm.
nitrifiers come out of untreated tap, makes one wonder why an aquarium open topped and contaminated for 30+ days is such an impossible source. How hard do they work to keep drinking water clean
Imagine how dirty a 45 day tank of standing water will be that on more than one occasion had bare human hands in it and had zero disinfectant properties upon startup 45 days ago
This read was challenging but interesting in that it outlines scum layer associations between heterotrophs and nitrifiers....same community different food sources but in the end a self supporting nutrient sharing web
The reason adding a light fish bioload to a tank that has set with water 30-60 days doesn't have the same clouding, smell, and ammonia registry as it does by adding them on day 1 is due to a base seed of these communities that is the result of natural cycling. They take off fast upon full bioloading, few days time
I never thought that water only cycling would handle instantly a full fish bioload, but the cycle does begin and can handle the early fish loading measurably better than inputting the same bioload day 1
Show me a water sample devoid of GAB heterotrophs and I'll agree there are no nitrifiers.
We can find nitrifiers thriving in places not expected we can easily see
The lfs that used to tell their customers to wait 30 days after tank fill to add fish had this basic concept as well.
