Predict daily water evaporation and calculate top-off requirements based on tank surface area, temperature, and humidity.
Enter your tank's surface area (length × width) and room conditions. Having a lid significantly reduces evaporation.
Evaporation rates can increase dramatically in dry winter conditions or when using cooling fans in summer.
Use the weekly and monthly estimates to size your Auto Top-Off (ATO) reservoir appropriately.
开放式鱼缸每天通常蒸发水量的1%~3%。200升鱼缸在常规室内环境下每天可蒸发2~6升。加盖鱼缸每天约0.5%~1%。配有底缸和加热棒的海水缸蒸发量通常最大。
加装玻璃或亚克力盖板可减少50%~70%的蒸发量。夏季可将加热棒温度设定降低1~2°C,减弱大功率灯具发热也有帮助。室内湿度越高,蒸发速度越慢。
会的。只有淡水蒸发,盐分不会随之消失,因此水位下降时盐度会升高。珊瑚缸如果漏掉一天的补水,盐度可能从35 ppt升至36~37 ppt。务必用RO/DI纯淡水补水(而非盐水),条件允许时安装ATO自动补水装置。
用每日蒸发量乘以希望的自主补水天数即可。例如200升缸每天蒸发4升,30升储水桶可维持约一周自动补水,足以应对短期出行。务必同时安装低水位断电保护装置。
室内暖气会将空气湿度降至20%~30%,大幅增加水面蒸发梯度。同时加热棒在冬季运行时间更长,水温略微升高。两个因素叠加,冬季蒸发量可能是平时的两倍。
