水草情迷

我的缸加厚了5吋沙, 暖管被迫被沙石活埋1/2長度,
支暖管會否會爆或影響效能?

no ! very dangerous ! no matter under any circumstances. The heater should always constant water flow around it in order to gain equal heat transfer across the glass surface or else cracks will be found !

那麼我用膠片圍住暖管下半部,行嗎?

not sure, may be the sensor won't function normally since the water was trapped in between the plastic. also,depends on the placement of the heater, in vertical or horizontal direction.

都係o個個問題
heat transfer in plastic is slow
similiar to 被沙包住
其實你可以斜斜地咁放支暖管

支200W暖管對於我個20吋缸太巨型,斜放d水草庶唔晒

Well in this case, plant more grass, the grass will grow soon or later. You hardly found you heater back !

嘩~ 我個18"缸都係用枝80watt heater,呢個天時.開到最細溫度,已經成27-28度,你個20"缸,支heater成200watt,多我果支一倍有多,
開到最細都會唔會過熱呀~ 小心無端端有菜湯或者魚湯飲wor~

而且我以前都試過好似你咁,雖然我只係放支管o係沙面,未至於話埋葬支管,雖然支管無爆,但日子有功,支管向沙果面煲溶左d沙,痴左o係支管到,
到而家都整唔走,死未~

用濾筒的嗎?
買支hydor外置暖管, 卡記一百八十大元正

管的周圍都有吋半空間,加上上面有水流,ok?
