haahh. i tried this dude. looks very good in your pic. i used a 4000l/h pump and by god it was a shock to the fish. im just going to buy a canister filter. so simple lol
heres another cheap diy filter idea

I don't think it works very well. That tube doesn't have a lot of air in there, so it doesn't promote bacteria to grow (when bacteria digest ammonia and nitrite, it needs oxygen), and scrubies are not very good as a mechanical media. You also don't want to combine mechanical and biological filtration in one (in this case scrubies) b/c when you have to clean the mechanical part, you also cleaning the biological part too, and that's a no no.
Correct.midnight;1473655; said:post pix if ya do
i think its both
mech is the blue filter stuff
and bio is the scrubbies
right?lol

I don't think you have a good concept of how a sump filter works, in this case, as most, the 'air' (oxygen actually) is carried by the water. At the speed and size of this filter, this will suffice.HoangLan;1478223; said:I don't think it works very well.

Scrubbies aren't being used as a mechanical filter here, they're for the biological.
You always pre-filter a biological filter or the bio-mat with become clogged and in turn kill any bacteria on the bio-mat by suffication
You clean the biological part of a filter by gently rinsing it in used tank water to remove detritus that can accumulate after a time, the bacterial doesn't wash off the biological filter material.

ya it didnt work good so i ditched it
it might work for thatPharaoh;2413571; said:
Bummer that you ditched it as I was going to suggest running airline hose inside it like you did with the 2" PVC DIY filter (except you used a smaller PVC pipe in that one )
Also, as for air getting to the bacteria, you could add a non return air valve at say ¼" from the inlet so that air can flow in but water can't flow out.
Just thinking out loud

thats why i post these posts
maybe someone else can tweak it like i tweaked someone elses idea lol
FIY, the AC media, will get clogged really quicky. I found this out when I came home and found water all over my floor because my filter overflowed.
I use an old gravel syphon, power head and media bag with established gravel or media when setting up a new tank. This isn't pretty but it works well to keep water cycled until a new filter is seeded...
It's a similar concept.
