如果co2溶解器設係缸外.....應放在出水位or入水位......
請各高手教教小弟......

硝化細菌係好氧菌....放o係出水位會好o的....

死喇.....出水係入濾水器定入水先入濾水器呢..??

但缸外co2溶解器擺係入濾水器之前好d喎...

如果你個溶解器係好似 Dupla S 咁 100% 溶就放 filter 之後，如果係就咁打 CO2 入去見得到溶唔哂既就放 filter 之前。

Macbrush, Dupla S 約幾錢，係唔係呢隻？

濾桶是密封環境，照計不適合好氧菌喎！

剛買了一隻 ISTA Co2溶解器，個盒的 instruction 教外置或內置式時都係接入水喉！

這隻 ISTA 其實和 Golden Age 那一款十分相似，但 Golden Age 那隻在拆除出水花籃後並沒有接駁軟喉位，不能作外置式使用。

我自己就打算接瀘桶入水！

Macbrush, 都好大枝喎，好似唔多常見，功用如何？你接出水口？

I use a separate 3500L/h pump to drive it.

BTW, LONG TIME NO SEE!

硝化菌藏係生化環，生化環藏係濾桶，我諗你指既連結所指既"密閉的過濾系統"唔係指濾桶，濾桶有水流經過，而水中係有氧氣的。

3500L pump dedicated for this purpose, WOW .... what is the total flow rate of all the pump in your aquarium? I know you have a big aquarium, but this is still a surprise to me.

Indeed long time no see, we should get together for breakfast or tea sometime, and I definitely interested in checking out your setup if possible, should be a very different lesson when compare to others.

無深究過，但濾桶沒有空氣接觸面，無法補充氧份，而 N-cycle 會耗氧，所以照計濾桶己是整個魚缸的低氧區，是最適合厭氧菌生存的空間了。

Actually, because of the flow inside a canister is fast, there is no chance to completely deplete oxygen in the process, not even close in a normal canister meant for biological filtration, i.e. nitrification. If you want induce denitrification, you need to have some extremely dense filter material so that flow is extremely restricted and evenly across the filter materials (any dead area will result in sulfate production which is poison), and means to control the flow very accurately, also with lots of testing for good results.

Thanks Macbrush for your explanation, it really helped.

According what you said, it is basically impossible to achieve, because even when you can do that when you setup the canister initially, the physical filtration part will start to filled with wastage and the actual flow rate wil change gradually as a result of that, so we basically have to monitor and ajust the water flow continuously which is beyond the reach of most hobbyist.

On the other hand, I believe it is fairly easy to include a flow rate sensor at the out-pipe and provide reading of actual flow rate while the canister is in action, this is a very good indicator on the performance and condition of the canister and can be used as a reminder for regular cleaning work

I actually think if a planted tank have NO3 problem, there is something very wrong. A established tank with thriving plants should need NO3 supplement instead. I throw at least 3mg KNO3 into my tank everyday, still not really enough.

You're right Andy. I guess that's way all new Eheim have a flow indicator.

I think this is indeed the way to go, much better then those fancy design and exaggerated flow rate, or even those so-called build in mini-watt UV for 2000L/hr gigantic canister !

To some like us, we are not aiming at planted tank, I describe my setup as community tank, and plant are merely for decoration and hiding/resting place for fishes, so NO3 is indeed a threat to these "unusual" planted tank.
