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.

you could use a float switch to measure the water level, then the size of the pump wouldnt matter since it would fill to a level and not an amount of time. as long as the pump is big enough at least.
n as for getting water out of your tank, you can just manually siphon it out since you might wanna vac your gravel anyways

Discus Only- Thanks! That's exactly the sort of thing I am looking to buy/build.

I do have a Python- but with 2-120 gallon tanks (plus a 29 and a 28), I'm wasting a lot of water when I empty. I do gravel vac each time I do a water change, but need to move a lot of water and I like to do pretty large changes every week. My oscar thrives on them.
