WHY DO I HAVE 2PPM NITRITE WITH ZERO AMMONIA IN A FISH ONLY TANK.

in no way possible is this cycle stalled. Simple fish disease did kill a fish

I'm talking directly to his question as to why he has nitrite. not why the fish died. Bio filter not strong enough to handle the load.

reasons for the cloudy water: we need to see some getting fixed first, to know if you had the cause all along. a fix is above, we cheat blasted with uv.

installing uv does not boost a cycle meaning cycling isn’t the locus


we collect false nitrite read work threads, this is one.

...what?

You can read Daniels link for details. It shows nitrite handled and clouding unrelated to being cycled. No cycling chart written agrees that this tank here isn’t cycled, but I read that in your post

the only reason I test this is to see if bacteria are predictable, if there are indeed cycles not done by ninety days it means they’re not predictable, cycle charts w be useless

Cycling a new Biocube 32

Hello all! My name is Daniel from Florida and I’m starting to get into the reef hobby. I have been cycling my tank for two weeks now and logging it into an app. I have recently been gifted a live rock with some good amount of coralline on it. I also got some water from and established tank. My...

Indigo, post a pic of your tank, we compare it to the one above in timeframe and occurrence like a map

Tank always seems hazy..

I can't figure it out. IM 25 Lagoon. InTank caddy's. Floss/chemipure in one. Floss/Marine pure in the other. Eshopps Nano Skimmer (Which is really only running so I can use a C02 scrubber.) and a Chaeto Reactor. 1/2 gallon water change every day with Versa's. I cannot get this thing to be...

same issue but see how it’s being troubleshot from a non cycling angle. At least we have some links to consider one way or another, directly related to issues.

In my opinion it’s dry rock curing boosting planktors of various annoyance, since we did burn it with uv back to clean and since Daniel was not using gfo, pellets or any adsorbents. Only rods feed and phyto were added.

if we used solid purple coralline rock this would happen less often imo


its all white rock pre cured starts. This is why BRS likes a four month leadup, seal in some of that curage with a biofilm then plant corals.

corals during curing = that’s where the fun is

This is a 275 gallon system that has been up for 3 months. Today I found a dead fish, no apparent reason. Zero Ammonia. 2ppm Nitrite. 100 gallons of seawater changed one week ago.

How am I getting nitrite with no ammonia?

Seawater, originally cycled with Dr. Tim's. Never had any ammonia detected. This is my first test for Nitrites.

Also, this tank has always been white/cloudy. Tried Dr Tim's clear up with no results.

Any thoughts/suggestions?

Thanks.

precipitation?

The tank has been up for 3 months. Its cycled. Nitrosomas double population in about 12 hours - so there's really no such thing as a "not strong enough biofilter" once its established.



Cycling is a red herring here. It has nothing to do with his issue.
