Why do y'all say that J. Prostrata is gone? He's been around recently (although not on this thread). Do you know something I don't know?
Because different algae process & store N and P compounds in different ways, and at diferent rates. For example, Hincksia, Derbasia, Bryopsis, Chaetomorpha, Ulva, and Botryocladia all exhibit different levels of N assimilation and uptake kinetics (... along with other differences). Similarly, different algae host different guilds of epiphytic microbiota (which are also utilizing nutrients from the water column). ZEOusers often report persistent algal populations in their ecosystems, but typically not the "nuisance" species.<a href=showthread.php?s=&postid=12133369#post12133369 target=_blank>Originally posted</a> by BradR
I don't understand, if zeo strips nutrients from the water why algae would even be an issue?
Actually, it depends on which marcoalgae is being considered. Chlorophyta species (green macroalgae ... like those typically applied for use as nutrient exporters) do indeed tend to extinguish, oftentimes rapidly, in ZEOsystems. However, both Phaeophyta species (brown macroalgae) and Rhodophyta species (Red Algae) have beeen reported to be persistent by many ZEOusers. Calcareous macroalgae can thrive in ZEOsystems.<a href=showthread.php?s=&postid=12137351#post12137351 target=_blank>Originally posted</a> by Zedar
... macros die off in zeo tanks.
The Kallmeyer article is a pretty good one, but we need to be careful with some of it. The notion of a "selective preference" for either ammonia or ammonium in a naturally occuring zeolite immersed in an ionic solution like seawater is entirely undemonstrated. The kinetics are the kinetics, and the electronegativity hierarchy is well established. However, differences in ion-exchange affinity ... Affinity ... for NH3/NH4 are well documented.<a href=showthread.php?s=&postid=12137889#post12137889 target=_blank>Originally posted</a> by Zedar
... They preferentially trap ammonium. ... heres a good article on how it works.

Hmmm ... for this to be true there would have to be the presumption that neither iron-oxidizing bacteria (IOB), nor sulfur-reducing bacteria (SRB) strains were present either in the ZeoBak, or our systems. I'm not so certain we can meet this prerequisite.<a href=showthread.php?s=&postid=12137889#post12137889 target=_blank>Originally posted</a> by Zedar

Similarly, if you're after the growth patterns and color "pop" of a ZEOvit system, you're going to have to confront ... dare I say it? ... metabolism. Strange that no one wants to give Mr. Pohl his due credit in this area.

If I may presume ... as far as nutrient reduction goes ... it's all about what's going on with the biofilm in the reactor (hint: mass transfer). Everyone seems to want to get lost in the inexplicable fascination regarding the adsorption properties of zeolites in seawater (it's really not all that impressive) ... go figure. I suspect you'll find that the "optimal" flow and on-off cycling periods are going to be different (compared with a reactor filled with an aluminosilicate media).
If I may presume further ... don't give up on the notion of "mixed" carbon sources. The literature is clear about this ... different strains do different things with different carbon sources. "Monoculture" is a myth, trace amounts of selected heavy metal ions are not inherently "evil", and a single carbon source does not an optimally happy biofilm make. Even so, the pic you posted speaks volumes, so the kind of maximization that I'm talking about may not be of interest to you. Similarly, if you're after the growth patterns and color "pop" of a ZEOvit system, you're going to have to confront ... dare I say it? ... metabolism. Strange that no one wants to give Mr. Pohl his due credit in this area.

To get at "tweaking" the metabolism, you're going to need more than an inert colonization media, a carbon source, unknown amino acids, and "food". You're going to need ions that participate in cellular osmoregulation, electron donors, and enzyme & cofactor precursors ...
... and the means to deliver them.

So its your belief that the zeolites provide this? Or just the Zeo supplements?
While I personally much prefer the Korallen-Zucht product line to the alternatives, one of the wonderful things about the DIY configuration(s) that you and Zedar are talking about is the opportunity for experimentation.<a href=showthread.php?s=&postid=12142887#post12142887 target=_blank>Originally posted</a> by sailfintang

I find the whole probiotic systems thing to have a pretty steep learning curve--or maybe it's just trying to figure out the effects and interactions between the KZ supplements that is so challenging.

As far as direct manipulations go, potassium still has me pondering. While potassium salts are what they are, the early reports of ground-up health store pills containing KCl leave me concerned (... although folks like Bebo77 and a few others seem to have finally worked it out). Until I've had a chance to fool around with the Warner Marine blend (I have great cost savings hopes, given the general quality of this product line), my personal choice is to use the Korallen-Zucht K-Strong. Even so, the potassium test kits currently available leave me questioning their validity, so I must confess that I'm not entirely confident as to what degree of manipulation I'm actually doing. You pays your money, and you takes your chances ... your mileage will vary.

The other elemental manipulation that I'm most concerned with is Fe. My personal favorite is the KZ Fe concentrate, but other less expensive Fe supplements should, in theory, be acceptable. Indeed, there's an argument to be made that a less powerful supplement is more appropriate. If Zedar's assertion that the DIY matrix-bacteria-vodka configuration is simply "less aggressive" and doing "the same thing" as the ZEOvit "basic 4" ... then it strikes me that a less powerful Fe supplement might be in order. While I disagree that what's going on at the bacteria guild level is the same, I concede to the logic.

All that being ranted, on the the fun stuff ... amino acids. The picture that Zedar posted presents what I think of as the "pastel phase", and Zedar is quite insightful and correct in choosing to supplement amino acids in response. My personal choice is the KZ amino acid concentrate, but it seems to me that there are alternatives that don't suffer from Euro exchange rate, and freight charges. I'm looking forward to reading other folks' posts regarding their use of such alternatives.

I believe that there is a fundamental synergy between amino acids and iron. AA & Fe supplements are simultaneously acting on different sets of life forms in our system ... corals, algae, and bacteria. While it is tempting to think of AA and Fe suplements as acting solely on zooxanthellae, what the user sees in the response of bacterial and microalgae populations are diagnostic. Biofilm & microalgae "blooms" are indications of over-dosing, and are very helpful to me as I "dial-in" a dosing regiment.

I have a question for you . K = potassium so why can't potassium cloride be used to mix up your own K balance mix ?
Can or should I say will you ( Mesocosm is a very smart guy ) tell me the pros and cons of this theory .

I used this at two teaspoons a day. i dosed it for a week. Within two days i noticed the pocco returning to its original color. My green slimer has become darker. blue tipped stag now has bright blue tips . In the pic you/ll notice the tips are pale blue.
Still waiting on the rest, but im hopeful.
