well here's hoping an algae section starts ... i would think a sub-section like the plant one in beginners. ... anyway ...
the little bits i know about algae from my own experience and what i have come across on the net
staghorn algae - you DO
have an ammonia issue
greenspot algae - (going on readings - seems to agree with my tank) - potassium deficiency
greenwater isn't a true algae in the typical sense
cyanobacteria - not true algae - theory - water O2 and circulation issues
-and can contribute to ammonia problems - see staghorn algae
-i'm going on all theory for cyanobacteria
other algae's, ... i'm rather clueless about
for others concerns for algae concerns on here, for my own curiosities and concerns, ... i'm asking to see what knowledge can be found, shared, learned.
i would to see additional information on these, ... both on removal, and on intentional culturing of.
there are many resources i have come across that say "excess of one nutrient or another" and another site will say "deficiency" ... for the same algae for the same nutrient ...
staghorn i have the most experience, ... and in controlled amounts is a very nice addition to a tank, ... too bad it doesn't stay that way :(
staghorn i have had twice, ... once when starting my tank, adding fish before the nitrogen cycle had finished, ... so ya, a bit of elevated ammonia (and other stuff going on associated with establishing a cycle
second time was with a massive pH shift causing an ammonia spike due to ammonium being converted to ammonia ... and a cycle had to begin again, ... and without anything else staghorn started up again, ... once things got settled the staghorn disappeared.
for staghorn it may not be ammonia per say, ... could be elevated nitrites, ... either way, something in that cycle is my hunch.
do i know if staghorn is favoring a particular pH range ... i dono, ... but from 6.5 up to over 8.0 no staghorn at various times, ... so i'm guessing more ammonia (or nitrite), ...
... i would like to hear others knowledge about having algae
both their hunches, their findings, ... things they have done consistently that have resulted in algae again and again (either accidentally, coincidentally, or intentionally)
thank you everyone for your input.
