hi.. i got the same problem.. i used powerhead equiped with venturi valve. it's very noisy. i tried to put a some kind a muffler in the venturi air intake tip, the noisy sound reduced but also the air bubble... is there another solution to make venturi less noise without reduce the function?

wow.. do really use that kinda filter on your aquarium? the filtration's result is water ready to drink..hehehe

thanks...your explanation is kind of logic. i don't have to modify my canister then...:D

i read this article: Simple Nitrogen Cycle | Biofilter Media & The Nitrification Process ..and hopefully not mistaken. it says: bio filter is nitrification process. two bacterias call Nitrosomonas sp (turn ammonia into nitrite) & Nitrobacter (turn nitrite into nitrate). they both need oxygen...

does anyone know? closed system such as canister filter open system such as wet/dry trickle, sump filter

i see. thanks for you info..

another question i read some articles, they said that bacteria consume oxygen. so this the reason behind wet/dry trickle filter is the most effective bio filter method. cause the water flow on the open system makes a good oxygen exchanged. my question is: how to enrich the water with oxygen in...

ok, i understood.. just my thought, bio-filters work by using some bacterial organisms and the filter media (bio balls or ceramic rings) maintain them there. so, no matter how clean the water is, the bacterias will keep on living inside the filter. right?

thanks for your opinion. do you think the bio filter still work effectively if the water is 'too clean'?

dear all: what filter media should be placed first in filtration flow? i'll try to combine all filter type, mechanic, biological & chemical in one unit the flow process show like this: dirty water - mechanic filter - chemical filter - biological filter - clean water or dirty water -...
