Actually, “I got stoned and I missed it”.

This a interesting paper in part about a relationship between bacteria and the macro algae Ulva. Jason Sent from my P00I using Tapatalk

Yes, some macro ingest bacteria.
http://open.uct.ac.za/handle/11427/6175 I like this article that shows a co-culture of abalone and Ulva.

Red Macro
Because of the demise of two Tangs in one week, I now have the opportunity to add some decorative macro to 75G Jaubert Plenum.
In the case of some of the Red Grapes that have photoadapted to higher light, I will bring them into this tank. I also will add some more Dragon’s Tongue, Halymenia digitata, which will be in a tumble culture in two days.

Also, in regards to the algaes removal of NH4 during the day & night cycle, the difference in removal percentages between the two identified abalone farms; Danger Point and Jacobsbaai, indicates there may be other factors involved. Perhaps bacteria played a significant role? In any case, a mechanism where-by algae takes up NH4 during darkness must be identified. |

Yes the percentages were different for each farm but they were consistent from day and night for each, if that makes sense. Jason Sent from my P00I using Tapatalk

Found this - Ulva efficiently removed up to 85% of the ammonium from fish pond wastewater in darkness or light independently of temperature fluctuations. https://link.springer.com/article/10.1007/BF02180927 & "A preference for amrnonium over nitrate has also been observed in other subinerged macro-phytes, such as Ceratophyllum demersum (Toetz,1971) and Myriophyllum spicatum (Nichols &Keeney, 1976b). In C demersum, nitrate uptake has been found to correlate with light intensity,practically ceasing in the dark, while ammonium uptake was continuous and decreased only slight-ly at night (Toetz, 1971)" |

With respect to Ulva, the fact that it can be grown in brackish water was of special interest to me. An indoor shrimp farm just south of San Antoine wanted to use Ulva to clean culture water after harvest. Because Gulf shrimp grow in brackish water, Ulva was the perfect macro for nutrient export.

This has me wondering if we should dose something like ammonium chloride at night to help speed up growth and in theory the algae would grow 24/7 and not just with lights on. I also wonder how uptake of ammonium and the subsequent growth at night affects the ph of the system. I realize that ph is driven by photosynthesis and respiration of the macro, I know this is more complicated than this I'm just making a point, but considering we know nothing about the mechanisms at play who knows.

I would not say, we know nothing about the mechanisms at play. You have identified part of the chemistry at play. When you adjust pH in a marine system, the alkalinity of the water acts as a buffer to resist pH change. It is for that reason that aroggonite substrate is a cornerstone of natural filtration. So, instead of only biological filtration we have automatic buffering and trace mineral addition.

Smokeless Sump
Quote:
What could you smoke in your sump? Tuna Fish. I have a true joke from having worked in “Blue Water for 35 years. After a difficult 6 month shipyard overhaul, when we went back to the deep water, a welding foreman came out with ship. Being in tuna feeding grounds, we fished every evening on the bow of the ship. Many crew members went to this deck just to enjoy the view and fresh air. It became somewhat of a hangout after a 12 hour workday. One evening, while fishing, I missed landing a yellow fin that I had fought for 30 minutes. My friend looked at me and said for 20 people to hear, “You can “tune a piano”, but you can’t “tune a fish”.

I finally caught up on this thread...trying to catch up on too many at once, LOL. Great read. BTW, your tank looks great!

With 900W of heat input water temperature of 400G was 60 degrees. I have got to cover tanks on these cold nights.
