Thats pretty cool...unfortunately, my tank is an aio..but i did manage to install a cpr bak pak fuge..If you have external plumbing, you can plumb one in. In my case, I literally used my back end-to-end weir area:

Growth said:4b. Trophic mode effect
The highest MGR [Maximum Growth Rate] of the HTDs [HeteroTrophic Dinoflagellates] is double the highest MGR of dinoflagellates growing autotrophically. Also, MGRs of small HTDs are much higher than those of similar sized ATDs [AutoTrophic Dinos]. Energy gain of small HTDs through feeding may be higher than that of small ATDs through photosynthesis. Also, enzymes involved in photosynthesis may lower MGRs of dinoflagellates and it is worthwhile exploring this topic. The range of MIRs [Maximum Ingestion Rates] of each HTD was 0.04-24.4 ng C per dinoflagellate per day, while that of each MTD [MixoTrophic Dinoflagellate] species was 0.03-7.0 ng C per dinoflagellate per day. Also, MIRs of HTDs were higher than those of similar sized MTDs (Fig. 5). Heterotrophic activity of HTDs (feeding and digestion) is likely to be higher than that of MTDs.
In other words, among planktonic species heterotrophic dinos eat more and grow faster than mixotrophic dinos. It's likely the same is true of benthic species. Perhaps we can recruit some to help us by providing them with a cryptic environment where they have the home court advantage.
Life cycle stages of the benthic palytoxin-producing dinoflagellate Ostreopsis cf. ovata (Dinophyceae) said:Several of the cells followed in this study were likely to have been cysts. The various forms included: 1) non-motile vegetative-like cells, also called thecate cysts; 2) ecdysal cells with the same shape as vegetative cells, known as pellicle cysts; and 3) round to elongated thin-walled cysts. All of these forms were detected inside threads of mucous and were viable for more than 6 months after their formation, consistent with the suggestion that those cysts could constitute an overwintering population responsible for bloom recurrence. Interestingly, only the mucilage-covered cysts survived in the samples, suggesting that the mucilaginous matrix acts as a protective coat
Emphasis mine. This suggests that an environment rich in heterotrophic bacteria and microfauna would reduce the reproductive success of ostis depositing cysts there, as the protective mucous layer would be eaten away and the cysts exposed.

Ran across this AA article http://www.advancedaquarist.com/2002/10/breeder on culturing ciliates.
I don't think a $100 UV is going to help with anything...
Taricha,
How does one ship a sample of Dino? I've never identified mine even though I'm hitting the two year mark with them (I think). I'd scrape some off my glass next time it builds up enough. I'd pay the shipping if you wouldn't mind identifying them for me. And maybe you get lucky and get the species you're looking for.
Maybe 10 days is long enough to commence the shift to a population of benthic microorganisms typical of a cryptic ecosystem powered by secondary producers, making mixotrophic dinos and their cysts food for hungry heterotrophs.
So while I'm not endorsing the idea, I can see a mechanism that might explain why tastyfish is...
i tried finding a reference to a $100 uv. I'm all in on a UV working, I'm actually about to purchase one of the emperor aquatics 18 or 25w. From everything I've read a cheap uv does nothing? Maybe I missed it? Would be great if that was wrong, I'd rather not spend triple that on one if a cheaper one works??
