We change water only due to nitrates its not for ammonia safety, that part can be skipped if you like. Your tank will smell bad if ammonia was ever an issue...stuff is very potent

if you want to change a good amount of water, your call on %

a fresh start may be less algae if we are lucky
If you change no water, no harm.

when a reef tank has sand and or rocks for attachment, and we are past the # of days on the bottle bac instruction alongside feed and dosed water and ammonia moves down from a high to low setting, and the water smells and looks normal, it means ammonia trends to .00x ppm long before a non digital ammonia test will let us see that.

Within an hour I suspect, that fast, not days. once it trends down it goes to the safe zone, and the tests simply will not let us see that unless we own a good working seneye.



should we ever find an example of high surface area in contact with known feed and cycling bac of the best possible strain, correct # of days waited, going grey crash and unable to keep a bioload after showing ammonia trending down this thread will have no purpose. The #1 gap we fill in for the old material is that the trend down is fast, consistent home to home, and doesn’t stall partially between 1+ ppm and .00x

it goes from uncycled to cycled (can withstand a 100% water change) in a matter of hours for the most active bottle bac brands. Dr Reefs ninety page bottle bac thread uses 100% water changes to ensure bacteria are adhered to surfaces, and it works when the bottle directions say it will.

we use too much surface area to casually leave the most important feed substrate (nh3) unused.


that is a truly fun gradient to be working against.

it doesnt mean occasionally a diseased fish or a bad acclimation or shipping ammonia burn won’t kill a new fish in a cycle one day. I just saw a kalk overdose post kill a fish too, things happen. Single losses are never systemic ammonia...the whole tank is visually wrecked of life when nh3 is not under control.


we are looking for obvious systemic noncontrol of ammonia nh3 and it will be so obvious, and smelly, when that happens that no test will be needed to see its effects.

old cycle rules gave nh3 noncontrol a wide variation of times it could manifest, like a minefield. Better buy an offset to make sure no pop ups happen


but a cycling chart has its ammonia stay down at day ten, no chart from any site shows it going back up for a reliable reason.


all we have to do to create the null condition is take a paint bucket full of dry rocks and input saltwater and ten good sized snails and a little food.

theyll be dead in max 36 hours, cloudy smelly water.

conversely, if you sub in cured live rock from the pet store, you have a nano reef the instant you set the rocks in the bucket. The snails will live and feed just fine.


rule:

Free ammonia can only trend to safe in a reef tank or it will trend to destruction, there is no middle ground holding. The trend is fast, within hours. That is the top rule in updated cycling science.

Team, we are backsliding. We are going in reverse as a hobby on free ammonia troubleshooting.

using our thread here for updated cycling science, none of these tanks have free ammonia, it’s how we are able to predict their entire reef status before they post update pics.


our hobby FALSELY claims that nh3 can be out of control yet all fish are fine, corals are fine, and lots of surface area is present. That’s a false claim, it happens when we exclude surface area mechanics from ammonia tracing threads. What ammonia does is predictable, it’s never never unpredictable

false unneeded bottle bac sales have happened now twice

do you see how the people who make cycling rules while selling bottle bac are doubly benefitted by using old science, yet robbed of boosted profits if we use new science?

Yes, this is completely true. On a PM exchange with Brandon, I setup a QT tank with new SW and a HOB filter. No fish. Added some media matrix to it and added a bottle of biospira. Gave it a week, tested water, no NH3, ~5 NO3. Added coral frags, all doing great. Once a week, add a pinch of flake food to feed the bacteria. Cycle done.

That is 100% agreeable
As long as rocks and sand are in the tank as attachment points all this time

fritz alone is instant cycling bacteria, meaning even if we added fish day one like so many thousands do, they still don’t die for lack of ammonia control

in addition, you are approaching day ten of any cycling chart, those tell us when bacteria set up shop, the ammonia goes down on or before that date especially when we’ve boosted known sources for filter bacteria

and you’ve specifically seen ammonia go down within the known range of the bottle bac.

the bacteria are plated on surfaces and immune to a 100% water change, Dr Reef found fritz able to handle this in a day or two max, after addition.

you are cycled by every marker we use, please update us! The living animals are the final say.

if your tank is in the least uncycled, it’ll go cloudy in two hours from the new fish and the whole thing will be dead by tomorrow. That’s not happened in any link here, or even one from the whole site.


no more bottle bac is due here. The initial sale was plenty and valid at that point.
So, to update you: one of the clowns died within 12 hours, but the other one is doing great. The one that died seemed really stressed and wouldn’t stop swimming against a strong current, even after I nudged him into a calmer area with a net. He just kept going back to where he was in the corner and never really settled in. We got another one today and it’s doing well too.

Not sure why some acclimate over roughly, glad the others are ok. Ammonia is such a thorough killer the water would go cloudy, the fish won’t feed or act normal, and they all die quickly. The #1 thing to watch out for is water clouding not so much a test kit reading, let me know if it clouds up as you begin light feeding/ no overfeeds and easing into full on reefing with the setup

thanks tons for posting!
