I'm thinking of building a DIY water changer using a pump and running an outlet hose to wherever makes sense given the time of year.
Has anyone done this and have any idea what size/type of pump would work well? I suppose I could calculate it... I have a foggy memory of doing so in my engineering classes years ago.
