Solbby, LMK know if you are interested in culturing\testing Prodibio products, I can bring some into the City for you.
Sure I would be interested, :) . Are you using it now and if so what is your gut feeling so far?

I have been using it for about 1 month and either the stuff is BS or my tank is too screwed up to see changes. NO3 is still at 25ppm and I am not noticing any color changes or growth spurs. Hair algae is taking hold in some spots, it may be due to not running the UV per their instructions(more like lack of).

See that's the problem as I see it. Dosing pure amino acids to ones tank is like painting a canvus with a broard brush. How do you successfully target feed corals when the other organisms within the tank will more successfully take up and utilize the amino acids. Bacteria/algae will always respond and use it quicker.

They suggest the UV filter to get rid of the "bad" algae growth stimulated by the amino acids. In many ways it is just another complicated dosing/adding (UV filter) scheme.

I meant not running a UV like I used to, they suggested not using a UV since it may kill some of the bacteria it is introducing and promoting. Whatever is in those little glass vials and no UV is causing hair algae to grow in the tank.

I guess these questions got the thread move to the advance forum?:sgrin:

Oh, see now that just doesn't make sense. You dose amino acids to provide corals with an essential nutrient that is lacking due to inadequent food supplies within the tank.

If you wanted to provide the amino acids needed for the corals via feeding (bacteria) why do it in the roundabout way? Just feed the bacteria (like zeovit), not add amino acids -> promote bacterial growth -> which provide food for corals. But I guess it all depends on the amino acids in the mix.

Shaun,
If I read your earlier post correctly, you seem skeptical of protein skimmers ability to remove bacteria from the water column? Am I correct? I raise this not because I advocate Vodka/sugar additions, but because of my experience using the AZNO3 nitrate reduction product which claims to work in precisely this way. In fact, it was speculated by some that the active ingredients -if you can call them that- are really just targeted bacterial food (sugars) that produe a bloom that consumes NO3 and are skimmed out. The product does in fact work very well and seemingly via this mechanism. I assume the "sugar" amount is calculated and the resultant bloom is resonably replicable that a "dosage" could be determined. Interestingly,the slight adverse effects some organisms experienced mirror your description of the bad stuff that would happen if sugar were introduced, but not to this extreme.

shaun i think if you want some great nutrients that will surly do something to your system. we should take some viagra and pour it into our tanks. =D

There is no evidence that skimmers skim out bacteria. If there is please provide it. Otherwise it is pure speculation, something that is all to common in this hobby. The whole concept of adding "things" to promote bacterial growth and then the little "guys" are removed sounds all to contrived and fanciful. Bacteria attach to things, and are rarely truely planktonic, except for true oligotrophic bacteria, which are most likely not to be found in our aquariums.

Don't get me wrong I don't know YET, if skimmers are able to remove bacteria, but I am not in the business of speculating without providing evidence after some period of time whether the speculation is correct or not.

Shaun,

I don't know if it is true or not. I find it fascinating that they may not be removed by skimming and then wonder what does a product like AZNO3 actually do, if it does not operate by the mechanism stated and does not work at all without a skimmer?

Are you implying that if I take a mouthful of tank water, I am not really ingesting any significant quantity of bacteria because they are not water borne? This would make me a whole lot happier when I try to start a siphon:)

It would be great if you could shed some light on the skimmate thing.

He means "amphipathic".

And for simplicity he is describing taking a water soluble molecule and binding a non-polar group to it, such that it becomes partially hydrophobic.

Definition of amphipathic :

Containing both polar and nonpolar domains.

The property of surface activity is usually due to the fact that the molecules of the substance are amphipathic or amphiphilic, meaning that each contains both a hydrophilic and a hydrophobic (lipophilic) group. This assumes that one of the two phases is aqueous, and the other non-aqueous.If both are non-aqueous (e.g. oil/air), molecules containing organophilic and organophobic groups may be amphipathic and surface active.
