水草情迷

45L水,請問用幾多L水流濾桶?THX

In general, around 10 cycles of water flow should be enough, i.e. for your tank of 45L of water, you need 450l/hr canister. However, do note that except Eheim, the quality of other brands varies much. Some of them are not as powerful as they have printed, some will deteriorate much after 2-3 months. Also, the specification shown is usually calculated on an empty canister, i.e. without filtrates, without connecting to other devices such as UV light, chiller, etc. That's why most of us will use "much stronger" canister.

thank you very much,but I have a old濾桶,(tetra ex90, 780L/H),is it too much stronger? thx

For my experience with Tetra, it should be fine for 45L water. 20" tank, right?

yes,it is 20" tank,but水流唔會太大嗎?因為準備做草缸同養魚仔

Tetra product deteriorates much and you don't need to worry at all. If it is really too strong at the start, you may drill more holes on the water outlet pipe. Or, make the water flow shoot on the glass. It helps slow down the flow.
