cloner machine pump

I HAVE an ex cloner 30 does anyone know what size water pump i needd? can i get one at home depot? cheaper? stopped working in middle of night

450 GPH submersible pump. Any should do, may just need a fitting to fit the sprayer manifold.

Edit: Some pumps may put out more heat than others, which can cause problems if you run the pump full time. If you find you're having issues with heat in the ez30, set a timer to run the pump 30mins on/30 mins off.

thanks for the tips pistilpimp
