one round of feed is plenty, we expect that much ammonia to cause non digital kits to stall in resolve for weeks on end (page one examples) but it will feed the bottle bac nicely along with carbon and nutrients from the fish feed. when fish food is not given during a cycle, standard room contamination provides enough carbon input as well as of the alternate nutrients bacteria need for cycling to be able to oxidize ammonia waste. the fish food speeds up deposition of bacteria on surfaces quickly per Dr Reef's bottle bac study thread.
at no time does any cycling reef require even a third that much ammonia, his instructions for everyone to dose that much overpowers nearly all test kits well past their ability to read accurately, and the result is a perceived stall, and then redundant sales of bottle bac in follow up.
also in play in false stall notions is the painted and stated fear from those same directions that ammonia over 5 ppm or nitrite/I forget which warning level it was/ causes a stall
and inputting 2 ppm ammonia per his rules at the start nearly guaranteed to make cyclers think its above 5 simply because the vial will be so dark they have to guess...so they buy new bottle bac thinking this addition has killed their starting cycle.
Old cycling rules are designed to cause doubt and sell orders of repeat bottle bac in my opinion. in furtherance of that notion, we don't have a single stalled cycle here in 29 pages and out in the postverse nearly every cycle appears to be stalled on the old rules, watch for new posts about it this week in forums we haven't even seen written yet. they're coming, every week are new stall cycle posts.
we are against that entire process here
not to be rule breakers but to earn one detail on every page every job that no other cycling thread lends:
a timely start date with zero losses reported.
starting with that much ammonia up front is the primary reason we elect to do water changes on an assigned date...the extra boost did not kill or stall ammonia processing, it fed the bac very well but overpowers the non digital kits with factors yet to be detailed. by doing a full water change on those ammonia blast cycles we remove any concern and replace the water table with known safe levels of ammonia water. (and then sometimes they still take a test and the kit shows high, lol, its wrong, seneye wouldnt show that see page one post #2 first link)
***it is very important
@discostew that we not post test kit readings from non digital kits along the way, this cycling thread is polar opposite of any cycling thread on the web for that reason*******
we don't test for nitrite at all here
and ammonia testing we either want calibrated as Brad mentions or as digital seneye uncalibrated, post those all day long.
what we use for proofing is fish in a clear water tank--that's what sets us apart.
Your arrangement disco stew can actually carry bottle bac instantly, on day one, the minute you dosed bio spira or Dr. Tims. the huge blast of ammonia may take some time to clear, but we don't track wastewater clearing time here so it will be unfactored in your assigned start date.
5 days, lol that's how long implantation will take for your setup discostew. In five days do a 90-100% water change and you have a complete cycle left on surfaces, per Dr Reefs bottle bac thread where all the top name brands were given measured time to adhere and then he did a full water change + retest as proofing, and those brands you use are done in more like 48 hours so five days is well beyond the wait time required, you just paid for concentrated bac in a bottle and it'll work for sure.
additionally, its not possible you bought two dead bottles of bac. by adding two different brands one is certain to work in this timeframe and 99.99% of the time both bottles were functional.
Your tank will carry fish just fine in five days + a nearly complete water change, regardless of what any cheap test kits say=what we've been doing here all year
thanks for posting, can't wait to see your pics of fish in a tank or hear about them
