Everyone that has planted tanks already know this. We want to know why algea stops growing when the plants grow well and are happy.dc88 said:May be the answer could simply be "because plants grow well hence no algae."
Alright, it was wrong for me to say that then (it was a late night post...), so let me also try to chip in my 2 cents of speculation then....defdac said:Everyone that has planted tanks already know this. We want to know why algea stops growing when the plants grow well and are happy.
May be it is not that algae learn to known oxygen and NH4 variation. But because that low oxygen and high NH4 were exactly the kind of environment they were first evolved in ?defdac said:Tom Barr aka plantbrain are the only one offering a glimpse of the truth of what might be going on here. Algae are tiny organisms that only bloom if there are no competition like happy plants and they seem to be able to know if there are other happy well growing organism around them - and it seems algae "listens" to variations in NH4-levels and Oxygen-levels.
When oxygen-levels drops and NH4 rises - time to bloom.
Happy plants means relatively small variations of high oxygen levels and tiny variations of very low NH4-levels.
How algae are able to listen to oxygen and NH4 I have no clue about though
Same here. My CO2 ran low a couple weeks back and bam! Plant growth came to a screeching halt and BGA was all over the glosso the next morning.Art_Giacosa said:In my experience, I have seen algae blooms when something happens that interferes with my plants' steady growth.
