higher flowrate filter promotes algae growth?

[tcy81]

hi all,

If i have 100L tank and i use a 300L flowrate filter.
will it promote algae growth?
if you compare that with using a 70L to 100L flowrate filter.

sounds underfiltered to me instead
300L/hr is about the rate of an eden501 or 2211

i have 30L tanks running on 300L/hr

haha, actually i am running 750L/hr on a 50L tank
think the material that i read from not so accurate ?

I do experienced BBA growing at areas that have higher flow rate.

I find this rather puzzling also. I have more algae growing on the plants just beside my outlet and on the outlet pipe itself. My supposely stagnant corners are algae free.....

quite interesting that dennerle website do quote that higher flowrate of filter in regards to tanksize will have tendency of algae.

Is it BBA?

it is possible, with higher flow rate, the possibility of algae spore to hit and stick to the plant or anything infront of the outlet is higher.

I have a 100L tank with a 1100L/hr filter. I needed high flow to blast co2 for misting method. BBA hanging strong right at the outlet of filter and i wonder why.

maybe there is some relations between high flow and BBA

[lEddyl]

mine as well. i notice it only occur in new tanks

I read somewhere that high flow rate will prevent BBA from getting a foothold. Thats why some of them advise good water circulation and flow. But this observation certainly doesn't apply to my jumbo jet filter outlet

[tcy81]

good flow will get the Co2 mist around your tank and prevent dead spots which in turn prevent BBA.

But i not too sure why BBA will occur on the outflow pipe
