Poll: Phosphate Export Preference

[bobbyM]

Corals are my preferred method of Phosphate control. Until then, GFO. Bio-pellets water changes and a skimmer are in use but I don't believe take out as much as GFO.

A fuge full of chaeto

+1 I have to dose phosphorous just to keep it measurable. And it holds a lot of critters that are good for you tank.

However a little reading about phosphates and im curious if one could test the link between oxygen, carbon dioxide and phosphates. Phosphates feed on oxygen and release carbon dioxide, which then fuels photosynthesis to algae? Could be really useful testing phosphates, oxygen, and carbon dioxide over the course of days, varying light output/time. When lights on the tank go out increase the oxygen to promote phosphate decomposition, what does phosphates test at in a couple of days? Im not really sure what the exact recipe could be but I do know it doesn't have to rely on coagulation or chemical removal. I think a good way to visualize this is in the course of over accumulated phosphates, say in a pond whose ridden with surface algae, then you may see a lake whose water is clear. The phosphates through the course of photosynthesis release carbon dioxide the carbon dioxide rise to the surface. However how to fully promote the gas exchange? The water is stagnant it doesn't move, theres no surface agitation to facilitate this gas exchange. At this point plant spores? not sure what you call them but algae uses this built up carbon dioxide and light rays to photosynthesize and create almost a blanket of algae. And this could have started all from an accumulation of phosphates.
These are merely thoughts it would be useful information to see how these parameters correlate with each other. Maybe these thoughts spark a thought you have or may have noticed through parameters. Any thoughts?​

I'm sorry, but that doesn't make sense. Phosphate does not react with O2 in any way, nor can it ever release CO2.

What did you read?

Are you maybe thinking of the reactions of organics? Those will react with O2 and release CO2, and also possibly release phosphate, if the organic contains phosphate (some do, many do not). That process is completely understood.

I started A fuge with cheato and a halo11 and now after growing 2 five gal pails of cheato I have zero/zero and have been FEEDING. Now a few acro frags colors are fading

Yes phos were that high, My CUC grew beards

other - skimmer, moderate feeding.

UPDATE removed half of the live rock and all marine pure then cleaned the sump a couple of 25 percent WC I will see in a few days if it drops, also started Rowas

 

[siggy]

Thought I would also mention this is a trition style sump with no sock , not sure if that's a good thing. It may be one of those Fads that in 2 years we will all say "What were we thinking"

I have no control - it controls at the moment. Tank is maturing and I have high Nitrate that is more pressing to fix atm But I did want to ask a question about GFO. Isn't that somewhat expensive to run with high phosphate?

Yes.

 

[User1]

Yes.

That is what I understood, thanks Not that I am interested in it but just wanted to make sure I was thinking of the same thing and all. Two in college I have to be somewhat creative in some hobbies This is one of them thus letting the tank mature while only addressing one thing like my Nitrates.

Have a good day.
