Filteration problem

[lyh]

Dear all I have some problem with my filteration system. Currently I'm running a 3ft OHF for my 3'X2'X2' tank with a 12-13" peru green and a 4" L190. The waste generated is alot and my OHF sponge choke in 3-4 days. I was thinking of adding another OHF to this tank and link them together hence the rainbar would look U shaped so that I don't need another powerhead. My main concern is I would need a stronger powerhead and if any of the joints come off, I can stay home and mop the floor and skip school for that day :o Do you all think it is workable? Any other solutions to this? :confused:

OHF sponge may have too small pores. Perhaps you want to have big pores sponge first, followed by the relevant elements..and lastly - the small pores sponge before the water gets out to the tank. Well, mine is ehiem filtration concept.

[SoToNgMaN]

is the bioload causing any water parameter changes like PH or ammonia ?

if not .. then there's no need to increase mech filtration via means of additional OHF ...

simply bring up the powerhead higher to avoid ****ing in the wood debris ... then remove those wastes via siphon during water change ...

Bro I deliberately chose the smaller pores one so that it can filter off lots of those poo. I also have wool at the bottom to filter those finer particles

Thye water parameter is not affected but the poo is really alot. It's really unsightly if the filter doesn't **** them up. ;)

if its mere unsightly only .. then dun see it lah ...

as long as it aint affecting water parameters .. its ok one lah ...

u've seen the amazon abyss show ... their river bed even more dusty than those on your field pack and SBO ...

My one today PH 7 ... tomorrow PH 5.5 one then headache ahh ...

Bro don't see then keep fish for what? :confused: :D

[SoToNgMaN]

selective blind lah ..

see fish .. then act blur cannot see shit lah ...

arboh how can u survive rattling of your wife-to-be ....

This skill is a must-have after you upgrade from boyfriend version 8.2 to husband version 2.2

Your style is fast cloaking the filter media or sponge. Hence, your mechanical filter media need to tune.

Big mesh>Ceramic Ring>Ceramic Substrate>BioHome>Fine Sponge.

Filter is always from big to small. That is how Sedimentation process is carry out during one of the process in water treatment.

Just my suggestion..

Mechanical filter only ! what about the biological filter ? :confused:

My OHF has sponge on the top level and glass rings in the two trays below for biological filteration.

IMO, OHF filteration system is more mechanical ( secondary ) and enclose cannister fileration system is more biological ( primary ). If I have "prize plecs" in the tank, I definitely wouldn't take the risk. Choice is your's :)

I believe bacteria will still grow in OHF system. I think they probably grow in the ceramic and biohome. For this reason, I advocate biohome to be the last to lessen the chance of biohome clogging. Also, for bacteria to grow nicely, they need to be shielded away from light. Hence, rubbish bin, canister filter are black out to block the light.....

My thoughts..

[barmby]

And btw, bacteria don't grow on plastics. Hence, those plastic balls that comes with "big boy" filter is not required. Even Uncle from Nam Hong say so :)

I'm reserved on point that "bacteria dun grow on plastics" ...

Believe vital to prior would be surface rather than material ... simply smooth surface provide lower surface area in comparison to matt/rough surface ... and smooth surfaces are harder to grip/root than matt/rough surface ...

Bio balls are often used in large scale denitrifier chambers ... reasons for use of bioballs:
- Assist in circulation/even distribution of water in chamber
- Induce resistance to water flow, assisting sedimentation
- Acts as binding hosts for anaerobic bacteria

Thus in conclusion bio balls (often plastics) do allow cultivation of BB ...

Comments all?

I was just thinking, if the filter wool is at the lowest tier of the OHF system, won't it be difficult to perform wool change?
Or u guys just rinse out the rubbish from the large pore filter wool placed on the topmost tier of the OHF system?

For reference of my OHF setup:

Bioballs (Top)
Bacteria House
Sintered Ceramic Rings (bottom)

mechanical down to biological ... often its rainbar thats choking rather than media thats choking ..

[barmby]

OK. :) Thanks for the info.

I could be wrong as well ..

very much, we are here to share and exchange ideas ..

Bro I got a question. Are there any differences for bacteria cultivation between using a canister filter and a OHF? Or maybe I put it this way. Any differences betwwen cultivating bacteria in a fully submersed condition compared to a wet dry one?

If you noticed, most of the external cannister are either opaque or very seldom translucent, this is bcoz' of effective BB cultivation, hence light or sunlight are kept to the minimum.
The other difference is the volume of water that goes thru " each " filtering stuffs. In a wet and dry system, due to the arrangement of output of water ( in rain bar or a single outlet ), some area are not fully utilise. Bet you'll notice the flow rate from each trays are different. Moreover each time you change the filter-wool, you actually reduce the BB effectiveness. There are more ! but you'll have to buy me kopi or teh tarik ! :D :D

Ok ok the next time I meet you I buy you kopi then you teach me more ok. :D

There r more than a million types of bacteria ... but generally could be classified into:

1. Anaerobic bacteria (No requirement for oxygen)
2. Aerobic bacteria (Requires oxygen)

Anaerobic is usually formed in canisters, harder to cultivate than the other, have a longer life cycle, harder to simulate no air environment thus comes DIYs by pple coiling long pipes before hitting into canister to reduce air dissolved.

Aerobic are usually formed in OHF or shower based filters ... easier to cultivate ... shorter life cycle ... easier to simulate ... but poorer breakdown performance in comparison to the other.

More can be searched from google based on above ...

Cheers

Bro but I thought anaerobic bacteria cannot be cultivated in cannister filter as the water is constantly moving through thus bringing oxygenated water there?

That's is where the kopi and teh tarik comes in ! :D if not surf the net ! :D
