algae affected by temp?
I'm going to leave this with...
For all you said, what you haven't answered is the riddle, other than to say "wrong". Ok, well, maybe we collectively are, that's fine... But, if, as you say, higher plants need so very much more of "everything" v. algae, just to survive, and all of that must be in the water at all times, else our higher plants are just dead beyond redemption... then... How is it anyone, ever, controls algae? Shouldn't it simply explode, killing everyone, and everything? Something must be limiting them. You seem to propose nothing, other than the mear physical presence of healthy plants. Surely algae do not inspect their environment, approve the health, state, and quantity, of the higher plants, and give up. (Aside - some higher plants to emit various biocides. Let's assume our swords do not. Further, reefs and silk plant tanks are known to exist w/o higher plants at all, yet are also subject to acute, resolvable, algae infections.) People have gone from no apparent infection, to acute infection, and back. I have, even somewhat routinely on my reef tanks. If, as you seem to claim, all higher plants must fail before nutrients can limit the algae, then what IS doing the limiting? Something is allowing routine reclamation of all these obviously inoculated tanks? (and not everyone is pumping their tank full of anti-biotics, particularly on the reef side.) *************************************** wrote: Principal causes of BGA has plenty of NO3, NH4 available in a tank if you have fish waste, some plant decay etc, you have plenty iof Nitrogen for this species. What you do NOT have is enough NO3 for the plants. BGA and most other algae appear when something runs out, rather than somethuing becoming excessive. When something runs out relative to plants. BGA need next to nothing to do quite well wereas the plants need far more. Adding more PO4 is not going to encourage algae if there's enough plant biomass that's growing, it's going to encourage plant, not algae growth. So when something runs out, lack of something, this harms the plants, not the algae. You pick the nutrient and the plants will always have a higher requirement than the BGA for both growth and maintenance with FW algae. You are not going to limit iron either, plants leech out more than |
