So yeah the check valve would work, but Im not a huge fan of them. Also make sure it's an all plastic one, as most at the hardware store have a metal spring in them. I use my mixing station pump to pump freshwater to the salt side, but if it's empty I can just let gravity feed it as well. My bins are dark so no light gets through to the water. I use 64 gallon rolling trash bins for water storage, so far no problems. Lots of people use the brute trash bins as well.Hello,
I am brainstorming my water storage setup, and have been having trouble figuring out how to fill my "salt" side without having it backup into my "fresh" side. Seeing all your photos, I'm highly confused by all the plumbing. I have 2 food-grade plastic 55 gal drums. I will be putting in a float valve in the "fresh" one. My plan was to simply connect the 2 tanks with a hose and let gravity fill the "salt" side. In my head, it seems like all I would need is a ball valve to stop the "salt" side from filling when I do water changes. But, the backflow is still a consideration at the refilling stage. That brought me to the idea of a check valve. It would require both.
I'm wondering what you all think of this.
Also, I'm wondering how to keep a bunch of algae from growing in the fresh side as it sits full for days/weeks? Do you guys keep a bunch of freshwater snails in there? Maybe a pleco
