Hi all,
Water change always an interesting topic.
Here is a method simultaneously for the simple and rapid water exchange in several tanks.
I use this converted Float Valves for Toilets. (Photo 1)
For small tanks I use mobile valves. (Photo 2)
For larger tanks they are permanently installed. (Photo 3)
The level-height can also be adjusted. It stops automatically when the tank is full.
It’s quick and saves time for the hobby important things.
How often and how much? – Because everyone has their own philosophy.
Greetings Arno
