Simulating rainfall, water change
Is there some thing i can buy at the hardware store to mimic amazon rainfall during water changes that i can just put the water into and walk away? could i use PVC with 16th inch holes drilled at various angles? I used a nozzle with "gentle rain" setting today during a water change and the fish enjoyed it, it also let me "sweep" under the logs and stuff, pushing detritus to a more accessible area of the tank. Since i have a sand bottom, the "gentle" needs to be emphasized here.
A few members have mentioned that slightly cooler water simulates a rain, which promotes spawning... are fish sensitive to sounds or water motion as well?
Also, the plants getting hit with gentle water seems to brighten them up, as well, maybe taking off some of the stuff that settles on them over the course of time?
If this is your 54 gallon with Angelfish,tetra's (snacks) and corydora's, the cooler water at water changes will simulate the cooler rain water that fall's in tropical water's which can be considerably warmer depending on time of day,season.
Could also use product.. "Black water extract" which will give the water a tea colored effect which the fishes would find closer to natural enviornment.
Fishes in wild generally associate rain with influx of food being either washed into the stream or lake from runoff or spawning signal due to cooler rains and temp change.
Could be they spawn knowing that during the rainy season,, there will be lot's of food entering the system which fry can feed on.
