I went back and reread that article again, they used multiple mixes of bottle bac, charted an ammonia drop within the known timeframes, and still considered themselves stalled/useless biofilter
I thought that just happened on reef boards from web posters.
I wanted to verify how they got bacteria into the emergency holding tanks.
clip from the article:
"During the renovation of the historic Dallas Aquarium at Fair Park in 2009-2010, aquaristswere placed in a similar predicament as the rigors of construction led to the time reserved forcycling and stocking of exhibits being constrained to a miniscule period. Two of the largestexhibits, a 220,000-liter shark tank and a 34,000-liter stingray touch tank were among the first tobegin cycling with multiple doses of bacterial inoculum from multiple manufacturers, but evenafter 40+ days the biofilters of both remained unable to effectively process nitrite (measured asNO2-) to levels safe for teleost fishes. During this time, additional cultures of NOB were added,temperature was elevated, and diligent additions of inorganic carbon were made, though thebiofilters were stalled and unable to complete cycling in the constrained timeframe. During thisperiod the authors received communications from colleagues and microbiologists that eachsuggested potential deficiencies or problems with the biofilter."
that means even phd's who run zoo exhibits are using 20 year outdated cycling methods. that's astounding to me.
