水草情迷

I prefer two canisters for large tanks. It's easier for maintenance and standby purpose. Also, you may need to connect them to other devices such as chillers and/ or UV lights,... etc. Having two will give you better control of the flowrate of the water.

Eheim 2228 x2 should be ok.

Troop: Are 2217x2 enough for hkguoguo's tank? It's of 250L of water...

2217串联难度高吗?

串聯當然無難度。 但係你應該唔會串聯丫。 分開并行好 D 喎。

2028 唔係唔好﹐ 不過你要留意一點。 2028 的入水口係斜的﹐ 當你要放兩個濾桶入櫃時你要留意 D 喉。 若果你個櫃可以平排放兩個桶就問題不大。 若要前後放就有麻煩。 2215/2217 係直上直落﹐ 就算你 4 個桶 “田“字型放都無問題。
