Cycle Stalled?

Nothing is odd to me in this hobby. If you're concerned that ammonia, nitrites, or nitrates are too high and stalling your cycle, nothing bad will happen from a 50% WC. I've done a WC in the past when my nitrites shoot above 5ppm during a cycle. Whether it helped moved the cycle forward or not, who knows, but it definitely didn't harm it.
That shouldn't affect the bacteria in the tank right?

Not likely. The nitrying bacteria you're after colonizes on surfaces and not in the water column. If it's already been a few weeks of your cycle, the rock/sand/ceramic media should have most of the bacteria you're after now. Changing the water shouldn't reduce bacterial load by much, if at all.

I’m in the same situation. Day 26 of cycle, and I’ve had Ammonia, Nitrites and Nitrates all in very high amounts since day 8. Ammonia still isn’t gone—about .25 , nitrites are as high as kit goes 5.0. Nitrates about 80. I’ve done two small water changes. Weird beige fluffy stuff on everything. I have 4 snails in the tank now,

Having the same problem. In my case ammonia is being consumed in <24h, which is a good sign. But my Nitrites have been high for 7-10 days now at least (off the Red Sea scale). I also did 2x 50% water changes and still have high Nitrites (and Nitrates). Frustrating though it can be it's really always just a waiting game in my experience

I have a similar yet different problem, I used a frozen shrimp, removed it after 3 days. My ammonia levels went to 1.0 ppm, Nitrite to .25 ppm, Nitrate to 5.0 ppm. I thought everything was happening, for the last 4 days the the Ammonia level is at 1.0, Nitrite at .25 and Nitrate at 0. I'm thinking of adding some more ammonia source either a little fish food or another shrimp to get the process going again. Good idea?
Oh and I added some bacteria at the beginning.

Read my build thread. I have three points:

1. Between 2 bottles of Dr. Tims (purchased from different dealers at different times) and one last one of Fritzyme Turbo 900, only the Fritzyme (which is stored by dealers refrigerated) dropped the ammonia in the predicted timeframes.
2. Nitrite can go on for quite some time, especially in a dry-start tank. Like months. I started my build in September, and I didn't see true 0 levels until January.
3. If you are dealing with marine fish NO2 should not be a concern at typical aquarium levels. Read here: http://reefkeeping.com/issues/2005-06/rhf/index.php

There is a very neat rule of thumb to consider for this thread

cycles come in two ways: forum cycles vs convention reef cycles.

forum cycles will not allow a start until api shows zero ammonia, nitrite but some nitrate. any variance to that set is deemed a stalled cycle.


but reef conventions use different rules, and have done so since probably the 70's or 80's

they cause an entire room of instant-aquariums to be in place, and cycled, by a start date and not by variance

All the reefs posting in this thread have an option between the two approaches. if at any time someone feels they want their reef ready by a given date this week, we can just opt into the convention ruleset and have that done.

Dont assume convention cycles are weaker just because they're skipped, or 24 hours set...they're not weaker. Nobody trusts a partially cycled tank to house 50K$ in frags. we're the buyers, they're the sellers thats how reef cycling works.

so to flip the script, just opt out of forum cycling

above when nitrite was mentioned disfactored, that's part of how they do it agreed/nitrite no longer needs tracking.

neither does nitrate...we know its being produced by rule if ammonia goes down even if api doesnt measure any.

ammonia control is where its at. getting api ammonia to reveal true ammonia control vs a stuck cycle is second key detail to unsticking any stuck cycle.

Thanks Brandon429, personally I'm leaning that way, I've added an ammonia source, monitoring the ammonia level. Going to remove the source and see what happens.

Bacteria, dry rock, the salesman turned me away from live rock. I am not sure it was the right choice though, time will tell, he warned against hitchhikers obviously.

with feed (shrimp decay) and bottle bac in place it will cycle, even if test kits dont indicate so.

how many days has this mix been stewing in the tank? day 10~ change out the water, add new water, and it will work/be cycled. all bottle bac is done in ten days + feed, its been tested by Dr Reef already. People report ranging numbers during cycles; that's just bc all the tests are inaccurate and they're testing wastewater with guess testers. we do opposite...

so we dont factor what measures people report regarding a cycle; only the known details of boosts applied, and submersion time.
