no my water is tapIs you water RO ?
I have heard people having persistant cyano issues due to poor quality/poorly remineralised RO water.
Can algae fix help me out with this?
Based on their chemical nature as compounds with specific functional groups, humic substances have the ability to interfere in the photosynthetic electron chain. This means, they act as weak herbicides and may structure the primary producer community in brown water lakes.
A recent comparison of the development of a coccal green algal and a coccal cyanobacterial species up exposure to various humic substances revealed that the prokaryote appears to be much more sensitive the eukaryote. This agrees well with field findings: In eutrophicated humic substances rich water bodies, cyanobacteria rarely dominate. Hence, we are trying to apply humic substances as a kind of natural mean to combat cyanobacterial development
Hi,Cyanobacteria have phycocyanin and some have phycoerythrin. Both are pigments that help to extract energy from green and red (shorter wavelength than chlorophyll red absorption peak) light, so light with a higher colour temperature could give cyanobacteria a competitive edge.
Clive!! thanks for dropping in =)Hi,
There is no advantage in this sense. Plants also have phycobiliproteins as well as other auxiliary pigments. So light with higher or lower color temperatures is not an issue. What is an issue is that light with high PAR does more damage to plants as their structures are more complex and they must expend energy to repair the radiation damage. The simpler structures of cyanobacteria and of other algae are much less affected by higher energy levels.
The OP should ensure filters are cleaned, that water changes are kept up and that KNO3 dosing is correct. If the dosing is determined to be correct and if BGA still appears, then flow/distribution as well as lighting levels should be reviewed.
Cheers,
No it's not, a 3 day blackout and extra NO3 will remove it. Start with a 50% waterchange and a tank cleanCyanobacteria is very difficult to get rid off
