Is there a benefit to having a rainstorm device?
I noticed not to long ago a forum member mentioned they were going to build a rainstorm device for there aquarium, is there any benefits to this and can anyone point me in the direction of a good link please?

Imitating rain can help induce spawning in many fish. Other than that, not sure.

I'd like to know exactly what this means.

Fish consider a water change as a rain, due to the influx of fresh water with usually different parameters; especially if it is slightly cooler (a couple degrees). I see increased spawning activity after most water changes, but especially if there is a low pressure system that day. I don't see how a device could replicate all this. :question:

Maybe people use it to make their loaches dance? :rofl:
Byron does have a point though. I just assumed it's something that.. Makes rain.

I've actually heard about these types of things. People use them to slowly raise the water level in the tank to induce breeding behavior. Unless you're trying to breed fish like this, I can't really see a need for them.

If you're talking about a spray bar for the water return of a filter, that can be used to decrease current and increase surface agitation. I've thought about getting one for my goldfish tank.

It is sort of a spray bar with a super reduced flow to simulate rain drops, can be hooked up to a timer to go on for a certain amount of time, return line hooked up to a reservoir to replenish water and then come on again later.

The effect has been known to stimulate fish into breeding.
