You're right.. Circulation plays a big role in preventing algae. You can install an internal powerhead like the Hydor Koralia line (my preference). You probably wouldn't need a very large one. The nano 240 would probably work well.
As far as algae: Is the algae limited to low flow areas? What type of CO2 do you have (or are you looking at)? Are you fertilizing and if so how? What kind of lighting do you have set up?
Sorry for the late replay but took a while to find my post hehe. :icon_bigg
First of, if i do get the nano 240 , where do i place it in the tank? At the bottom of the HoB filter side of the tank pointing forward, up, or down? Or should i place it across from the HoB pointing up, down, normal?
As for algea, its almost on every plants, i have water wisteria and water sprite both on 2 corners of the tank across each other. The sprite is taller then the wisteria and on the side with HoB filter those seems to fair better but they still have a bit of algea. The tank also have lots of other plants in the middle, some of those have really bad algea growing on em eventually turning black but for some reason new growth on top of those plants seems ok till maybe a month from now. I cull em weekly to try to keep the algea population low.
As for CO2 i use seachem excel flourish daily about 1.5mL. I recently got Seachem Potassium and Iron so I dont know how well they're working yet. For lighting i have 2 24 watt t5 zoo med light. One is "flora sun" the other is "ultra sun" not sure whats the wavelenght/spectrum theyre in tho. They run 8-10hrs a day, maybe a little over more if i get home and dont turn it off.
Like i said its a big mess, but fish and water parameters seems to be ok. 0 amm, 0 nitri, prolly 20-30 nitrate. Last part is probably one main cause. The other main cause is probably due to not mineralized dirt/soil. Didn't know about mineralizing soil till a month ago. :icon_eek: But the tanks been running for about a year now. :smile:
