水草情迷

大家用緊既暖管.有幾大差誤到呢？我較左30℃，但熱極都係26℃到。

我較左20度，佢就係保持23度；爭幾度應該冇問題掛！

我較21度,都有22-24度
65L水用75w暖管

唔同缸大小, 唔同w 數o既組合, 仲有水流, 出黎o既效果都唔同喎. 用緊乜牌子呀.

p.s. 主題寫清楚, 等人一睇就知嘛, 唔駛估估下吧. 又改了啦, 唔該.

If your 暖管 always trun on......that mean your 暖管 already reached its full power. Then it should be something else.. as SuperCTW said.

我無用暖管o架，我養斑馬、燈魚、金清道夫、白老鼠、重有側魚仔幾条，呢個冬天個缸最低都未試過低過12度，我覺得天然環境適者生存係好重要，而且有10小時開燈，而且係室内，啲魚重未有一条死過，啲草生長就比較慢，低温會處於休眠狀態，咁咪可以唔使成日剪草囉，但係若果養七彩神仙就一定要暖管。

我較26度,都有22-23度

我果支JBL pro temp 100W冇乜溫差

冰刀貓... 請問你枝JBL pro temp 100W的燈有冇閃爍的情況呢?

it isalways 28度
wtever i set how many 度

我果支冇閃呀@@.

我用緊Tetra 150W，不過唔知點解，我較左30℃，但個缸經常得26℃到，但係支暖管仲唔係長著，好多時係熄左。支溫度計係支暖管隔離添咋。

係唔係開放式呀果缸?
我試過開左頂之後開埋窗咁比佢吹,同埋唔開窗唔開頂咁計....係可以差成5-7度架@.@

我個缸冇頂，不過唔近窗。

冇頂 seem to be the reason for 唔係長著.... your 暖管 seem not sensitive enough or the water circulation is not good or the position of your 暖管 is not correct.
I am using Hydorsafe plus 2 50w 暖管 for my 50L tank and I have a 頂 totally covered my tank but also have one 風扇 turned on. When the temperature is warm (a month ago), it is quite accurate to the temperature I set (26°). Now It always have about 6°C difference quite agree with specifications as the user manual. It seems that I need to add another 暖管 with the temperature is too low.

Energy input is from 暖管.If the water circulation around your 暖管 is good, than the energy is transferred as heat to the water. The heat lost is due to the heat transfer from your tank's water to the surrounding. The energy input is constant depend on how much w of your 暖管 can provide if the light of 暖管 is on. When the surround temperature is dropping. The energy lost from your tank to the surrounding will finally equal to the energy output of your 暖管. Therefore the temperature difference will become constant. That means the 暖管's power is not sufficient.
