Tropic Marine BIO-ACTIF Salt 

Tropic Marineから販売されているBio-Actifの人工海水の素。DOCが意図的に入れられており、使用するにはプロテインスキマーが必要とされている。下の記述はこの塩の開発に関わったHans-WernerさんがRCにコメントつけたものです。

By Hans-Werner
I just want to show up some facts. The book of Sorokin on Coral Reef Ecology is the scientific book on coral reefs I like best because of its multitude of facts and because it brings them in context.
On page 66 Sorokin states that the content of reef water in organic C is around 1 to 3 ppm. The carbon content of starch is ca. 44.4%. If all the organic carbon over the reef would be starch or similar substances there would be 2.25 to 6.76 ppm in the reef waters. Why shouldn´t it be a good idea to add organic substances that for sure can be found in reef waters in significant amounts? In my eyes we have added something that was lacking in synthetic sea salts and not something additional in comparision to natural reef waters.

As you know for the measuring of organic carbon we would need special technology which we don´t have. The addition of organic carbon through feeding depends on the kind of feed and the amount that is fed. For example it seems to me that granular fish food does not contribute much to DOC. Besides this feed also add nitrogen and phosphates which speed up the degradation of DOC.

In the reefs there is DOC and POC that is more readily degraded by nearly any kind of bacteria and other that is only degraded by specialized bacteria with the necessary enzymes. We tried to support the latter ones. The introduction and initial support of this specialized microbiology is in my opinion one of the most important functions of live rock.

I am convinced that a better understanding of the dissolved organic substances will be a big progress for reef keeping and maybe also for the understanding of the natural environment and maybe we can make some people curious to take a closer look on it.

Finally all this doesn´t matter. We tried something and it did work and we made the same observations that are described in this thread, polypextension, better colors, clearer water, so it seems a good improvement and a good innovation to us. Now it is up to the reef aquarists to decide whether it really is an improvement and a good innovation.

炭素源と苔 

Bacterial Blooms - High additions of carbon sources at once are noted as production of slimy white strings upon rocks or in sumps that become noticeable a few hours to a day after addition. There is no clear evidence that this is detrimental to your tank. If this is observed dropping your dose by 50% will result in the disappearance of these strands.

BioPellets 

BioPelletsのスレッドをRCで見ないなあと思っていたら、Chemistry Forumで議論されてました。結構スレッドを伸びているので、今後に期待。個人的にはもう少し具体的なデータ(栄養塩濃度など)が欲しいところです。

KZ社のCoral Snowと他の添加剤の相性 

KZ社から販売されているCoral Snowって製品があります。以下が説明です。
“Coral Snow is a liquid form secondary biological facilitator for elements such as Bbalance and Potassium-Iodide/Flouride Concentrate. It is also compatible with Amino Acids and Coral Vitalizer.
Coral Snow contains a natural calcium-magnesium carbonate among other ingredients. The particles as well as the other compounds can be taken up directly by the corals. Coral Snow neutralizes unwanted acids and yellowing compounds and can be beneficial in the prevention of e.g. slime algae and cyano bacteria.

We dose Coral Snow daily, every time with a different element, The necessary amount of Coral Snow is poured into a small container and mixed with the to be dosed element. Gently mix and let it sit for about 5 minutes. Then add it directly to the tank at an areawith high water flow. You can use 0.5 to max. 4 ml Coral Snow per 25 gallons daily. The initial cloudiness is not harmful to fishes or even the most sensitive corals.”

要するに、B-Balance、PIF、アミノ酸、Coral Vitalizerなどの添加剤と併用することにより、サンゴに直接摂取させることが可能だとの事。本当なら画期的な商品。Fauna Marinなども同様の製品を出してきているので、これからのトレンドになる可能性も無きにしも非ず。

bryopsis (ハネモ)撃退法 

RCのスレッドでKent Tech M(マグネシウム添加剤)を使用して、マグネシウムレベルを1600ppmまで上げることでBryopsis(ハネモなど)を撃退できると読みました。その中で面白かったのは、Mgレベルが1600ppmが原因でBryopsis(ハネモなど)がなくなるのではなく、Tech Mに含まれている亜鉛・銅によってBryopsis(ハネモなど)がなくなるのではないと書かれていました。なるほど。

因みに、Tech Mには以下の成分が含まれているようです。
magnesium, chlorine, sulfur, calcium, potassium, bromine, strontium, boron, fluorine, lithium, rubidium, iodine, iron, molybdenum, zinc, nickel, copper, manganese, vanadium, cesium, cobalt, tungsten, selenium, and chromium.
