why dont they? I know they dont but i dont know the explanation/ science behind it all, can someone help please
Thanks.
Thanks.
Why should they? They don`t cause plants.

I can only refer to the Barr Report Newsletters mate, other than my own tests as well.
Cheers,
ceg4048 said:When you see algae attack a leaf it is specifically because the source of the ammonia is the leaf itself and that usually means that the leaf is decaying as a direct result of malnutrition.
When this happens it is a sure sign that malnutrition is at fault so dosing normally has to be increased even though it feeds the flagellate forms. You'll just have to live with this short term escalation of algae in order to stop ammonia production due to starvation.
SuperColey1 said:Ceg, although I agree with what you have written above you concentrate on malnutrition. Should it not be added that the slightest damaged leaf will have the same effect ammonia--->algae wise? This is easily shown that when doing a water change with a syphon (and I am not the most careful) that if you catch a leaf, then a few days later algae can be seen. If you look at the actual leaf it is healthy and isn't decaying and continues on for infinity but the algae remains on that damaged section. I get this all the time because (as I said above) I am always getting leaves damaged from syphon water changes..

This part is bang on the target.

This part less so. EI is about growing plants, and that is it. Follow the ethos of EI correctly and algae shouldn`t come in to the equation.

Andy, it might be worth trying an experiment for a few weeks in which you supplement the tank with Excel/Easycarbo, or if you are already using it, to increase the dosage and/or frequency slightly. There is a strong possibility that your CO2 distribution is marginal which perhaps makes the leaf more susceptible when damaged.SuperColey1 said:My Co2 must keep running too low (or not dosing enough nutrient) Every leaf I damage gets staghorn or BBA within days.
I shall have to keep an eye on it.
