求助藻類名 - 疑似Dinoflagellate

[danmhippo]

有沒有人知道底沙這種模樣是哪種藻類造成的? (還是細菌類?)
顏色為黑灰色, 略帶黏性, 沙子顆粒會被黏成一小塊一小塊的,
但又不像紅泥藻會長成一片可小心剝除

我確定不是底沙老化或是厭氧菌造成的, 因為我的底沙還挺白的
下面這張是10cm的底沙側面照 (活沙系統的上層沙)

我的底沙有還不錯的水流 (Vortex MP10), 這種藻只局限於沙層上, 水流多的地方比較明顯, 光照不到的地方則長不起來.
第一次發現大約三個禮拜前, 逐漸長成這個醜樣,
水質資訊:
pH = 8.5
KH = 10
NO3 = 30
PO4 = 0.5 (左右)
Ca = 440
Temp = 24


任何資訊或建議都非常感激

可以試試看翻砂海星

我覺得是細菌類
現在我缸子底層(裸缸)有照到光但水流不強也佈滿這種東西
但是在水流強勁 不會卡沉積物的地方就被鈣藻取代

剛剛讀了Randy Holmes-Farley的文章, 有種很壞的預感我這些就是Dinoflagellate.

GlassReef is also encountering dino- problem and a guy elaborated his cure in post#508.

From your pics I saw more resemblances to cyanobacteria? If that's the case then ESE 500 mentioned in post#512 might be a good solution ~

I had Dino problems with my tank while I was living in Vancouver, the tank was about 1 year old at the time with deep sand/refugium system, what I did is removed all fishies to lower the amount of nutrient, added ozone to my skimmer combined with reduced lightening period and stopped using my calcium reactor for about a month, it disappear and never came back into my main tank; however, it still appears in my refugium from time to time with amounts I can live with.
It is not too hard to treat but it it's impossible to eliminate IMO, to contain it is the key!
