I, like most, have algae, and my thread and beard algae is present. I am curious as to why my slow growing plants seem to get the algae more than the faster growing ones. My anubias, Bolbitus and Microsorium get the algae muchmoreso than the Aponegetons I have (but the apo's get algae too but I can attribute that to the fact they are right at the top of the tank and in the most bright conditions with all the nutrients. I must confess that I have a small amount of circulation, and I will remedy this by a powerhead, but is this related to the fact of my algae/slow growers? I am buying the powerhead anyway, but if there is any other factor regarding why the slow growers get algae moreso than others, I would love to know.
