Now that I've got my sump plumbed correctly and everything, I was wondering about building an auto-top off system--does anyone have any advice/links to building one myself?? I've heard it can be done fairly easily and fairly cheap--thanks
Old salt bucket or a Vitels Vault from a PetStore if you want something fancier. Just make sure it is food safe if you use plastic and also make sure it can hold the weight.
