The part of the experiment that confuses me is the use of cycled rock out of an existing system. Without understanding that system it will be hard to make any assumptions about this system. "The Ugly Stage" typically refers to tanks that are started with dry rock and sand as they need to build up the biome that will out compete what people consider to be ugly organisms. If you use cycled rock Live or dry in a new system you can circumvent the ugly stage of a new tank which is why new tanks in the past that used live rock out of the ocean didn't typically have an ugly stage if the rock didn't have much die off in transport.

If the experiment was to see if you can start dumping nutrients into a new tank that has rock with an established Biome then it makes sense.

I just started a 300g tank with 160 pounds of dry marco rock and 80 pounds of established rock (it wasn't from the ocean but it was in three different well established reef tanks so lots of Bio diversity) There were no ugly organisms on the 80 pounds of cycled rock and the 160 pounds of dry marco had lots of diatoms on them until the biofilm was established which took about 6 weeks. At 8 weeks I am now seeing lots of coraline growth and the only ugly I have left is some cyano bacteria on the sandbed which is a result of me keeping the phosphate levels higher to help drive algae growth in the system (Phosphates are about .13 ppm and nitrates are between 2-6 ppm and I measure them daily right now). The tank had 20+ fish added right off the bat so a large nutrient intake and lights were on full from the beginning 150-200 par on the sand and 300-400 on the rocks.

I'm listing this out to show you can circumvent alot of what people consider the uglies by using cycled (dry or live) rock from the beginning. I also wanted to point out that the largest contributor to the results is not the nutrients you added but the fact you used established rock from a different system which is something I don't see called out much in the thread.
I see what you are saying and maybe it would be best for OP to help us identify what the "uglies" are. Is it diatoms? Dinos? green algaes? if we can name the uglies better than the uglies we may be able to get to a better idea of what is going on.

OP would you mind sharing a final shot of the aquarium. What did your tank eventually become colonized with do you think? thanks.

There is no difference between a carbon limited or a carbon balanced system imo.

This was literally the first comment after you opened this thread, but you gave everyone pushback/retorts telling them they didn't know what they're talking about:

What do you mean by balancing?

All reef tanks are carbon limited (or should be) with respect to bacterial growth. The ocean certainly is.

I’ve probably didn’t explained myself properly. I’m not experiencing nothing out of the ordinary with nuisance just yet.

My thoughts is that i shouldn’t be seeing film algae on the glass to be a sure thing, if film algae on glass can grow then other nuisances could also take place. There was a small impact on bubble algae that was in one of the rocks introduced.
I was hoping to be able to outcompete the diatoms if that makes sense.

This is how everything looking today, after cleaning the brown film on glass.

Yeah I think that is the part that is missing, the term Uglies (New tank uglies to be specific) is not very informative. I don't consider green algae to be part of the uglies as it is a normal byproduct of high nutrients in any tank regardless of it's age. I'm actually excited to see green algae growing as it typically means your biome is stabilizing. I do think many people consider GHA to be part of the uglies but in reality it is a result of you not managing your nutrients after the tank has cycled and can occur at any point of keeping your reef if you don't maintain nutrients at a manageable level.

To add I feel Uglies are more a term related to uncured rock or sand. If you add new marco rock to an established reef tank it will go through an ugly stage as it builds up a bio film. I have actually seen this happen on bleached and dead coral skeletons as well. The rest of the tank is fine but the new rock/skeleton with no biofilm will grow diatoms, cyano and other uglies and then green film algae (a good sign) and then coralline. This ugly stage doesn't last long since there is so much bacteria and other beneficial biome in the tank that it quickly populates with beneficial biome.

Thank you. Bubble algae is the bane of my existence. But everything has a role in my view. I’m trying to work with it more instead of against it. Thanks for sharing more and I hope you share more still.

I thought the "experiment" was over?

I don't think there is an issue with understanding what you are saying but rather the issue is that what you are saying can't be correlated to anything meaningful due to lack of protocols, controls, measurements or even a baseline to work from.

You’re now suggesting that film algae on glass is some kind of definitive indicator for whether “nuisances” will take place, but you haven’t established any causal or measurable relationship to support this conclusion. As it is, film algae growth is common in any system with nutrients, regardless of whether it’s "carbon-limited" or “balanced” (per your original premise). So I am a bit bewildered by your assertion.

You also mention wanting to outcompete diatoms, but again, there are no controls, measurements, or baseline comparisons in this “experiment” to support your observations.

Likewise, the small impact on bubble algae you mentioned is also purely anecdotal. What does “small impact” even mean in quantifiable terms? Was it reduced? Did it grow? How is this tied to your carbon dosing or nutrient manipulation? Compared to what?

These new tangents don’t resolve the prior issues raised in this thread and only add to the wandering away from the actual topic.

At this point, it feels like you’re throwing out random observations without addressing the core premise of the thread, if not outright avoiding it and any of the critique, open questions or inconsistencies.

Some say a picture says a thousand words. You claimed the crinoid would be dead? I’m assuming you mean the coral? Which doesn’t look like a crinoid to me. But if you are talking about that pink coral growing on the rocks it looks like it’s still alive. Am I understanding this correctly?

The crinoid did die some pages back. But was regrowing?

Unquestionably the same tank. Reported alive as of Nov 3rd or 4th.

From the first post in THIS thread on NOVEMBER 21st

The system has been just over 30 days dark with just mature media from a cycled tank in the back sump baffle, no mechanical filtration, just protein skimmer....

...The rock has been added yesterday to the system


Also note on November 3rd he indicted

I will leave the math and logic to you, but unless that crinoid and the 30 day dark tank are in a multiverse... both can't be, given the OPs direct claims and the timestamps on the threads and photos, as well as those in a few other threads.

oh from another thread? What does that have to do with this thread though?

What exactly do you think op is hiding? I don’t see it. Maybe he has 2 tanks. I have no clue? Do you know?

Still don’t understand what’s your problem with the timeline? The crinoid was introduced with the dark period. Not sure what you trying to get at?

I just laid out what it has to do with this thread. Yes I "know". The photos in the various threads show the same tank on the same stand from the same camera position. Let's not beg questions that have obvious answers.

I’m fairly confident you do understand the problem, as I’ve spelled it out four times now, and you’ve avoided addressing it directly.

You stated:
"The system has been just over 30 days dark with just mature media from a cycled tank in the back sump baffle, no mechanical filtration, just protein skimmer...."

Yet, based on your posts, a crinoid was introduced during the “dark period” and lived in the tank for ~15 days. It’s unclear if or when it died, but any algae, microfauna, or decomposition it introduced would have impacted nutrient levels, invalidating the claim of “30 days dark with just media.” Let's be clear, given your attention to detail in other areas, this is not a small oversight in language or context.

Furthermore, the tank wasn’t truly “dark,” as you’ve stated it was running with at least “10% blue light.” Additionally, per your crinoid thread, you were experimenting with taking the skimmer offline during this period.

These factors wouldn't be a huge deal in the course of an "ugly stage" conversation. However, in the context of your claims and the way you’ve framed this thread as an experiment with meaningful conclusions, they are yet another set of uncontrolled variables. This further underscores the highly speculative nature of your observations and undermines any valid conclusions you’ve drawn from them.

In parallel to "raw" bio-media, I might have simultaneously marinated some of those man made porous Brightwell bricks in that purple helix stuff (coralline in bottle), let some stuff colonize first for a timelapse photographic comparison. added/edit...NO CLUE if that algae in a bottle works or not, just sayin as a example...
  • Anytime you get even one post from any of the obvious qualified gray matter types, evoke every ounce of humility left in you and beg for suggestions.

The time frame and timelines dont add up. The tank has been running longer and under different circumstances than are being discussed by op here in this thread. That in itself isnt the issue so much but it invalidates most of this "experiment" not to mention it throws a shadow of doubt on what he is saying because its not 100% truth might not be intentional, they might just be forgetful. They also do not even register when told or questioned. This is the same tank in multiple threads. Eggs + 1 basket = wrong

What part of the timeline is wrong? can you explain how this invalidates his experiments here? I don’t get that part. Does having one tank in multiple threads not allowed?

I’ve answered that question a few times already

IMG_2519.jpeg


In addition 10% blue light is no more than moonlight or ambient light for a few hours a day, how would the 10% light affect the rock that not been in the display? You had enough time going through all my threads, did you see any rock in any of them.
I’ll also ask you the same question as I’ve asked the other member, what do you understand with the term just over 30 days?

There is folks doing 6 months dark and still experiencing an ugly stage, the dark stage is usually to ensure you have an effective nitrogen cycle. To your point what’s the revelation here?

This thread is only getting attention due to many not being able to finish the Redfield thread, they still have issue with some of the arguments that was raised in there, don’t think for a minute that there is anyone here trying to help. It’s an observational thread and look how much interaction it has been over here. Why do you think the moderators had to intervene several times?

I’ll give you a example.
Folks have been asking for a control, but what is a control, from two accepted control within the community we have the example of brs and aquabiomics.
Both controls were set up with deadrock no bacteria and water flow.

My question has been if I was to add this control to my experiment how different would it be from the know results of those two experiments with same results for control?

To me that request would be identical to me asking you to add a control in your experiment without lights and no nutrients.

Do you believe that if you were to add that to your experiment that you could gain from it?
The coral itself is heterotrophic only the symbiotic zooxanthellae is autotrophic.
