Algae prefers ammonia as a source for Nitrogen
Algae prefers ammonia as a source for Nitrogen
that's what I thought I'd read on here but cannot find anything about it
certainly nothing scientific!
Spend some time on ReefBase.org and you find things
Also, search the web for things like "algae ammonium uptake"
(Note the ammonium not ammonia)
Odd theoretical side effect:
The algae that do not bother with the nitrate-conversion bio-support, and concentrate only on ammonium directly,
will eventually out compete the other, so you can in theory end up with strains that do not really handle nitrate.
Not sure that would happen in an aquarium, but they do mention it in some papers.
Oh yeah, your lighting is very low, this could be part of it....Originally Posted by SeaTurtle
i changed the bulbs last sunday and i'm noticing growth already. one question though, is ammonium more toxic than ammonia?Oh yeah, your lighting is very low, this could be part of it....
Beyond Concepts...
ammonia/ammonium changes form relative to the pH of the water (and temp). High pH gives more toxic ammonia (If I didn't change them around), but they are come from "the same" source. (and you always have both)
i see... do they also affect pH directly? because i noticed when we did the second experiment (50 grams of fertilizer) the pH dropped from 8.4 to 7.4 instantly.

That would be carbonic acid in the fertilizer dropping it.
(which is part of another ongoing discussion on the forums atm)
Jeesh . . . listening to that guy (in the video), you'd think all our problems could be solved by algae.
I guess the closed loop is essential for not introducing strains of algae that would grow on the plastic, thus obscuring light from the flowing water.
Really interesting. Too bad it only has 12k hits. Should be on news casts unless there are negatives that aren't mentioned (as there always are).
