Slightly higher if anything I did notice my ph is a little low and my alkalinity is super low literally half what it should be so I'm thinking that might be why the cycle stalled

why did you put a reef in that

calendar reminder set to track disease expression outbreaks, expected by June '25 (8 mos is the popup time we can see by studying a thousand new tank cycle outcomes, or by scanning the first page of today's disease forum posts, and finding out how old their tanks are by selecting 'find all threads' from the thread author. the majority tank age when sampling multiple pages is 8 mos or less until the losses begin, skewing into very high % for white rock/dry rock startups)

your cycle is that kind, as I'm reading.

the cycle isn't stalled. you're using old rules we don't use anymore to determine stall/pass.


nobody writes articles on the new rules, we can't even agree on what they are lol but rest assured your tank is ok for basic bioload carry so its no wonder the old rules still are the most conveyed to readers.



the key is disease management, for sure. the prediction is that by June of this year, well into your cycle issues being long gone there will be post history about fish disease/losses. that's a powerful emerging factor in today's reefing... it saves money to take note of these trends for sure. to not take note of them, keeps Jay very very very busy on rotation. his forum is the busiest on the site, thousands of prep skippers coming due for help.

a fascinating thing about reef tank cycles is the lore of the failed or truly stalled cycle that kills things


try and find one of those. find three, see if you can find three truly failed cycles from this year and post those links

that's key, it's lore. nobody has loss cycles here, or anywhere.

where the real losses are:


what updated cycling science does is relay to you that ammonia control is no longer an issue, engineers have that all figured out we don't have to. 100% of all cycle planning is in the disease preps, that will keep your fish alive.

Huh I'm so confused
I'm pretty sure it's stalled hence the low alk etc and no change in nitrite. Why else would the seachem not decrease nitrite etc unless the bacteria was dying because of low pH etc which would mean it's stalled as no live bacteria left in the system

Bacteria is really hard to kill.

Dr Tim recommends a lower salinity to do your cycle I am doubtful your low ph and alk numbers are messing with . I am currently cycling a tank with Dr Tims and Marco rock at 25 ppt. My numbers will be all over the place for awhile I imagine. You have lots of chemical interactions happening inside your tank as it matures.

Adding too much ammonia will stall your cycle( per Dr Tim not me) So like people have said find out what your ammonia is at. Get your Alk in spec, make sure it is going to stay there and TAKE A WATER SAMPLE to the fish store before you buy fish. I bet they will analyze it for you to make sure you are good to go.

Day 18 nitrite looks over 1ppm still
Ph maybe 8
Alk 5 so very low still
Nitrate 40

So after 25 percent water change nitrite is the same, pH has risen slightly, kh/alkalinity is the same, nitrates have lowered. I don't understand how nitrite and alk hasn't changed after water change

If you want to boost alk, I'd just use baking soda. Water changes are a very expensive way to boost alk.
