that was a good read. it is a little out of alignment with todays cycling trends however, specifically: what reef forums are doing regarding nitrite.
search out any posts Randy has made on nitrite in display tank reefing, compare it to the highly detailed design there in that print to render nitrite neutral
we didn't need a detailed way to control nitrite in a marine quick filter setup.
see the first few paragraphs of the writeup on page 50: he labels the nitrite cycle as if it's consequential at marine salinities. those animals mentioned for saltwater tanks or zoo exhibits don't need nitrite cycling.
"potential deficiencies or problems with the biofilter." <--that's due to nitrite noncontrol, not noncontrol of nh3 which is the only factor that matters in marine tank cycling. they still hit the normal expected timeframe for that data point.
additionally:
in a standout pattern I'm seeing across studies (see Taricha's various threads as well) look at the initial ammonia drop being greatest on day 11 on that data from the article link.
what date on a 40 year old cycling chart does ammonia show to drop? just after day ten. their drop was on day 11. that's impressive.
impressive for the chart already existing before he proved it again in the data shown in the article... the ammonia data there is savory because it confirms what we've already been using in updated cycling science for marine aquariums. ignore nitrite, make any common effort at fostering ammonia control and by day ten it'll all work out fine. day 11 in that case above
*so it's not that coca cola did anything faster than we do here with skip cycles, or testless cycles which get any tank ready by a known need date. it's that he added another spoke to the wheel already in place.
you can do the same thing with fish food, there are hundreds of examples available online. the coke did nothing special
when we read above about them needing to redo the public aquarium and have a known ready biofilter for their delicate shark and rays display...a call to
fritz company to order several gallons of
fritz 9 would have done it, they could have input the sharks day 1 with the bottled bac scaled up correctly like we do here with two clowns.
we have ways of getting what they want much simpler, faster even than they did (we routinely build skip cycle reefs that control nh3 on day 1, not day 11)
what would have impressed me with that data above: if they were able to earn ammonia control faster than the charts show. they didn't. it's the only aspect of their biofilter design that mattered *other than total surface area* and flow channeling designs core to the tanks the fish were in.
