Hello guys just wanted to make this thread to see what kind of systems you use for your wc or maybe you have great ideas for that .. right now i have 8 tanks running in one room and i do 50% daily wc sometimes just cant find time for it .
So im thinking to make some automatic drain , refill system with some solenoid valves float switches ..
The idea is so i could only clean bottom of the tank every day without worrying about water + refill would be on timer so the fish would know exactly when the wc will happen ..

Maybe you have it done allready so you could trow me some ideas , pictures
