水草情迷

其實一個濾筒用耐左無力是否主要原因是磁心老化問題？如果係更換一個新磁心上去濾筒內是否可以解決到問題？大家有什麼意見究一下？

I'm afraid there are too many factors affecting the water flow, though I do agree that "磁心老化" is of the major reasons.

可以試試洗下d濾棉先, 可能有幫助~

I newly bought a eheim 2213 for my 18" tank. I feel the water flow is pretty weak. Is 2213 not enough for 18" tank or because I put 1/L mono ball into it? Thanks.

debono: If your tank size is of 18"x11"x11", 2213 should be fine. Having that said, 2215 would be a better choice if you're going to connect it to a chiller/ UV.

Thanks Fish Fan and sorry sfn8178, hope you dun think I hijack your post

it's lot of co2 stay still at the surface during the light and co2 are operating, that's why I wonder the power of the 2213 at my 18"x9.5"x12" tank. Is that normal to you? Thanks!

The accumulated bubbles may imply:
1. slow flow rate: This is what you are suspecting; or
2. bad water condition: The water condition is turning bad and the surface tension of water has changed that accumulate a certain amount of CO2. This may be caused by few changing of water, overfeed, etc; or
3. too much of CO2 supply.

我用2213係17.5"缸, 都發覺唔夠..
考慮緊由兩層白棉轉回一層

我話係因為用耐左，即係玩耐左，越黎越懶，攪到棉花過唔到水都唔換、菌膜越黎越厚，咁既環境，幾好力都會退化

我已經將兩層白棉轉回一層(拎走舊個層),
但出水仲係差唔多

可能本身係咁

leonhart: 2213 should be fine. Is your canister new? Is there a chance that dirt has accumulated and blocked the water flow?

Thanks Fish Fan, I'm totally understand Leonhart's concern. I feel my newly bought 2213 is a bit weaker than my last eden 511. Would it be better if I change all of my mono ball to bio ring?

磁心 only part of the motor (the inner part), the outer part would also 老化問題.
As a result, change of 磁心 cannot improve to certain extent - not 100%

一般濾筒摩打由磁心及外部線圈所組成, 線圈通電後產生的磁場, 這部分老化的機會會比較少, 隨非線圈的漆皮銅線氧化磁場才會影響, 一般磁心的是非永久磁,灰色個舊就係, 用耐了或經撞會影響磁性, 當磁心磁力下降,相對外線圈既磁場效應就會減低,轉速同扭力都會下降, 就會無咁好力。但大部分情況流量下降唔關磁心老化事, 反而係濾材污垢令水流減慢, 亦因為水族用既濾筒, 個磁心軸承要求唔會咁高, 用幾年後就會有一定既磨損,個磁心虛位多左,亦會影響轉速同出水量, 所以換磁心最好睇埋連條軸有無磨損, 有就一齊換埋好D!

師兄你解釋得幾正確，用耐左磁心一定有磨損你講得好詳細！我試試後再發表換後意見........
