nutrients and SPS corals.

[Allmost]

hello all,
need to get a vote ... so please only vote based on your personal observations, and not what you have read or heard.

do nutrients play a role in SPS corals ?

does different nutrients level result in different coloration or growth rate in your tank ?


do you notice SPS corals browning, or paling, or bleaching or .... when you make a change to nutrients levels, via feeding less or feeding more ..... skimming less or skimming more ... doing more water changes or not ?

do you see a correlation on how fast algae grows on front glass and how SPS corals look ?

 

[cugly]

From my experience it does change..my tank is clear less film on glass and colors are vibrant and growth is noticeable when nutrients are low and its opposite when high..I can verify it also with change in alk uptake slows down when nutrients are high and its other way when low..polyps are out when nutrients are low I dont test much anymore I look at my corals and able to tell that something is off thats when I test..

 

[sahin]

Voted.

Dont know/Porcupine made me laugh! :lol:

 

[biggles]

I'm going to go out on a limb here and say that a porcupine would definitely affect the acros if dropped into the tank, oh and of course i voted yes.

 

[Moser]

What's the purpose of this vote?, It's a no brainer.

You can lose colours with low nutrients, just as well as high nutrients…..

[tmantaylor18]

This is everything I never knew I wanted in a thread.

 

[Borchers]

IMO high nutrients have an effect on SPS

 

[trueblackpercula]

I voted yes

 

[cugly]

You should put your koala in the tank biggles and lets see what happens. .lol

I know ... what I thought since 97 too, and observed daily ... yet some recent threads on here argue that nutrients dont effect corals lol

Ah, I am guessing this means me - I have never made the argument that nutrients don't effect corals.

I don't read that thread as the same as you.

I ses it that way :

- changes in nutrients/water parameters certainly affect corals and this is worst when changes are always happening (no stability)

- with stability, you can have many, many combinaison of ligthing, nutrients and water parameters and still have beautiful corals. Including having high phosphates and nitrates.

why and how is still not clear !

not directly, but in your thread you have stated in regards to your own specific tank the following.

It wasn't any different when the po4 was lower. I got tired of spending time and money chasing the numbers and decided to let it go and see what happened. Not much.

which could give off that impression that yes you do think certain nutrients have little to "not much" effect on coral, Maybe you could tell us if you were specifically referring to your unique tank and setup or any and all aquariums in general?

 

[Allmost]

oh

"Nope! I also don't think the corals growth has slowed even with the po4 level. "

"It wasn't any different when the po4 was lower. I got tired of spending time and money chasing the numbers and decided to let it go and see what happened. Not much. I may try to reduce the po4 to see what happens, of course, how to quantify what happens is a whole nutty kettle of fish. I do go through and chop everything back every 6 months or so. Almost time for another round. I am also not sure how much I care about growth speed. If it ends up being a little slower, it just means less work for me. "

"I am almost always leery of whenever someone says 'everyone says' or 'everyone knows', as it is almost never the case. It is not the case that everyone thinks that corals react to a change in nutrients, especially regarding coral coloration, nor is it clear what you mean by 'react' or 'change'. "

"At home, I don't. I have a 180 gallon sump under the house that acts as an abyssal plane where detritus settles. I used to remove it from time to time, but what a pain, so I stopped and didn't see much of a difference in over all tank yummyness."


so perhaps its best to include that this is your observation based on one case [your tank at home ? ]

Most of the best tanks on here, Copps, Darryl, Big E, Luca, Mo, and ALOT more .... all talk about detritus management and nutrient management ... and ppl who follow it grow beautiful reefs. but not everyone with high nutrient reef has a beautiful tank like you do

okay that makes sense corals can adapt ... as they did for millions of years, I can agree with that and appreciate that. so perhaps that was the point. ... which wont guide new reefers in wrong direction

thanks

I voted, but i think it is a bit of a cheap shot against a very interesting thread/discussion.

The above mentioned thread is not the first one to show colorful corals in high nutrient tanks. i recently read a few on UR.

How & why that can be is more interesting than being proven right in a poll IMO.

Of course I am just referring to my tank - that is the focus of the thread. The "not much" is clearly and specifically about my tank.

 

[Thales]

oh

Of course it is based on my one tank. I don't understand why you insist that I am making any sort of general statement. I have not done any such thing.

Most of the best tanks on here, Copps, Darryl, Big E, Luca, Mo, and ALOT more .... all talk about detritus management and nutrient management ... and ppl who follow it grow beautiful reefs. but not everyone with high nutrient reef has a beautiful tank like you do

And? Where have I asked anyone to follow my methodology? And I have actually made a point that people not follow my methodology because we don't have enough information on what is going on.

That said, I know several tanks that are fantastic that consistently run high phosphate and high nitrate, but they don't post on RC (RC isn't the only place that reef tanks are discussed). I suppose my main point is that there may be reason to take a new look at some of our standard numbers.

This is discussed more in an upcoming article.

Very interesting observation.

i think it is a bit of a cheap shot against a very interesting thread/discussion.

+1. By the replies in this thread it seems it was targeting a specific individual/thread, why not continue the discussion in that thread instead of creating a new one?
