Circumference of Food??

[Lambianz]

A flow master ?. You have a circle, go ahead draw the circle. Ok you say what size, well hmmm maybe 2" circle. Now you have another circle at bottom center line of 2" circle. Go ahead draw the circle. Again you say what size. Well lets say about a 1/4 circle.
Now you have a big circle right on top of little circle. Now the bottom circle never spins. But the top one does. And..And the bottom circle is a food source. Now you can control the spin at which the top circle spins.
Ok here goes ?. There's always food at the source. Does the 2" circle spinning fast see less food or does it see more food spinning slow.

Ummm... your supposed to throw out your expired pharmaceuticals.
Either that or this is just a bad trip. Put on some Steely Dan, turn the lights down and you should be okay in a few hours. , What ever you do, do NOT look into a mirror.

This a highly advance question and only the reply above has had the effect their relating to, or else would have had a answer.

I wasn't expecting a smart a** reply. Was suppose to get the flow master involved in noticing a related topic of a stationary food source with flow of water passing through.

This is not a chat room, as they have the above sort of replies.

Lamb,

Not quite sure what your asking, but they way you presented it, it does read a lot like you've been sniffing the kalk powder. Perhaps you can reword it better so that we can figure out what your trying to accomplish with spinning food.

 

[Lambianz]

Its either getting more food spinning fast with more flow or its getting more food spinning slow. As of with low flow. Of course notice the food source always stays in one position. Kind of like what a UV light see's when water is either flowing past it fast or slow. You have a container of such and it can only hold so much passing water flowing through it and the amount of water it will also hold. But the food source thats seeing the flow is always there.

My answer to my own question would be the faster the spinning 2" circle, the more food it would receive.

I was hoping for a different answer and why they believe different.

 

[spleen93]

If I'm understanding the question correctly, the answer is: it depends. If the bottom point (circle) is a food source and you assume 100% capture rate and instantaneous transfer, then yes, the faster the top circle rotates, the more food gets exposed to the top circle. But extending this concept to a tank - if you're asking whether a stationary coral in the tank will get more food by speeding up the laminar flow in a tank, well, then that's a whole 'nother kettle of fish. Or if you have a feeder on the tank and it's dripping/dropping in food at a constant rate, then yes, faster flow will circulate the food better throughout the tank. As to whether the consumers of the food will be able to get it or not would be another matter (depending on particle size, capture rate, etc.)

Lamb, I am terribly curious about what you are trying to convey. Can you please give some context as to what you are asking about?

The title of the post is "Circumference of Food??", which leads me to believe that you may be asking about an automatic feeder, but I am not clear with the picture of the circles that you are wanting your reader to draw. When you say, "a flow master?" are you talking about a piece of equipment?

If you have a picture, maybe we could provide better feedback.

Sorry that I can't be of any help.

spleen was getting close to why would we slow down water going to our fuge. It is a stationary source to remove something in our water.
If I had a 1000 gallon tank, a 100 gallon fuge. Wouldn't I want that 1000 gallons of tank water to pass through the 100 gallon faster so the water will see the micro algae to remove the nitrates.

The big circle is related to the tank and the small circle is related to the fuge.

I've read and read about how micro algae is suppose to tumble in the fuge. And been researching the effects of some people having a low flow fuge and high flow fuge. Well they say with low flow everything is find but then you hear them later saying their having problems.

I experimenting with my fuge with the high flow and the low flow.
And my fuge is on a stand next to my tank. Same height of tank stand. So I can crank up my tank flow, along with power heads, and can control the flow to my fuge with a valve. I also have a power head on the in side of fuge with a pvc line on the out port of power head with a tee then further down an elbow pointing towards the slot openings to main fuge compartment where micro algae is. Strangely though when I plug in power head in fuge at different times, not on all the time, the micro algae grows like crazy. But when I slow down the flow, I start to get sagging algae and cyano starts and too, pieces of algae starts to break off. Maybe I need to read up on if cheato has a, hmmm how could I say this, like never stable.

Now that makes sense

As spleen93 said, it depends. The algae in the fuge will only be able to remove nutrients at a certain rate. If your flow through the fuge is slower than that rate, then it's not removing all the nutrients from your system that it could. If you have the flow rate matched to the algaes rate of removal, things are perfectly balanced. If the flow rate is faster, than nutrients are getting by and recirculating through the system. However, since that faster flow doesn't mean the algae can't pull out nutrients at it's maximum rate, and that perfectly matched balance point is going to be variable, I'd go for a faster flow rate As you noticed, your chaet grew better with some internal circulation added, so your looking to find a flow that gives you maximum algae growth. That will take a little playing with the flow rates

No it's not. It turns out that your question is very basic...one I see in the newbie "chat room" quite often. I think you just tried to make it look more advanced than you needed to.

Well...obviously I wasn't the only one that didn't know what planet your question was coming from. If you weren't trying to sound all esoteric and deep you may have gotten a simple answer to your simple question

Then what is it? :rolleye1:
I am glad we finally got your question straightened out though. I've been having a problem with the growth of my cheato and this give me an idea of what to look for.

 

[Fragman2]

Lamb, You referred to the Algae in your Fug as "micro algae", Assuming that you really meant Macro Algae then my experience has been to maintain a good flow rate through the Fug or add some recirculating current with powerheads or hydor type pumps. I did this on a friends 800 gallon system with a 100 gallon Fug and it made all the difference in the world. He now harvests a 5 gallon bucket of calurpa out of there every couple of weeks.

Ok now we are getting somewhere. This question was not suppose to be lets get to the point, but what is the theory of the flow in the fuge.
And I don't believe this is a English Major Forum. This is reef forum, none of use write the same or text the same. I am a engineering inspector with a degree. And all other cert's to add. I'm always doing trig and points of origin. As to relating to datum call outs and why as calculating these variable's, a certain engineering theory will not work or work.

But here's another problem, will a mix of grape, and cheato algae in the fuge compete for a food source?

I don't know everything when it comes to reading a book, heck half the time as we all know, many interpret what they want. so you may have ten different interpretations of what they read. Until they re-read again and say ahhh. Ok

I believe spleen was wondering or their mind was also clicking on well lets try this and see what happens. And not trying to analyze the post to why they didn't like how it was text or formated to their desires.

Thanks spleen!!!

 

[spleen93]

I believe that they will compete. They both require the same food sources - just that the grape caulerpa is much more aggressive / has a faster growth rate, so the chaeto is likely to lose. Having said that, I have both chaeto and grape in my refugium in different sections and they seem to be getting along ok (I very aggressively harvest the grape caulpera every 2 wks or so though - almost to the point of eradicating it).

Well now I believe that maybe, just maybe the problem isn't even the flow, to a degree, because as the couple of replies above, the person stated that when his friends 800g tank with 100 gallon fuge, add more flow or circulation to fuge, had a better effect on the growth of the algae in the fuge. When i got my fuge up and running last year and a half ago. Of course as new to the experience, I've had to remove and add more algae to begin a better process of trial and error. And along the way of getting either free algae from cutting back members fuge growth of algae, I've acquired, both cheato and grape algae. I can see the mix in the fuge. Not so much of the grape. But its there. Maybe the turning up the flow allows both to feed on the nitrates in the water without starving. So both seem to stay alive. But with low flow as mentioned above the grape algae wins. Heck sometimes I see it starting to grow in my tank and have to remove, the grape algae that is. So that tells me it feeds fast and moves around quick too. I've read before I set up fuge that cheato was a better algae to use in fuge and the con's of grape moving to the tank and growing out of control.

 

[billsreef]

Yup, grape caulerpa can be quite an invasive algae.

 

[Che]

I think that a lot of getting a fuge dialed in is trial and error. Not any one fuge is going to be exactly like another. I have had quite a few variations in my fuge. I have included sand, rubble, caulerpa, and cheato in my fuge as well as varying the flow rate through and in the fuge. My fuge is tiny compared to my tank and the best option for me turns out to be low flow through the fuge with an addition of a small powerhead in the fuge to gently shake the cheato. (I now only use cheato, it seems to be more dense than the caulerpa when harvesting, ie more nutrients removed) It seems that I cannot tumble the cheato without having/creating some other problem. I have removed rubble from my fuge even though it seemed to be a great at producing pods; it caused me more problems with nuisance algaes.

I hope that this is helpful.
