这是其中一种想法，当您的水箱管道时，可能会一次或另一次脑海中脑袋，但被告知不可能（或至少不是一个好主意）。为什么您不能只得到与您的排水相恰好，防止空气毛的泵，而不必使用BeanAnimal或Herbie溢出之类的DIY选项？
Although it was previously certainly possible by using over sized return and then dialing down the pump with a valve, you’d always run the risk of a flood if the drain is even remotely restricted be it a snail of natural build up of gunk in the pipes. That is where theReef Angel water level sensorand itscompatibility with DC pumpscome in, allowing you to adjust the flow rate of your return pump based on the water level in the tank (or overflow box). If the water level is too low, more water is pumped up, the water level is too high and the pump is throttled down. With the water level sensor able to detect changes of around 0.1mm (originally advertised 0.08 mm) the sensor is extremely accurate so you won’t need to worry about large fluctuations in the water level.
The main let-down currently is that only one water level sensor can be used for each Reef Angel controller, so you’d have to give up your level sensor in the ATO container for old school float valves, but that should probably soon change. Another disadvantage is that, like anything, there is always a change of failure so it is still recommended you use a secondary drain pipe in case something goes wrong. Once again Reef Angel shows us just how exciting the future of aquarium controllers is, and it is probably just a matter of time before other “more consumer friendly” controllers follow.
