I'm looking to DIY my own ATO Reservoir that can hold 10+ gallons of water. I found a container I like online that holds 15 gallons but it says its polyethylene and not specifically High Density Polyethylene but is for potable water storage. It still makes me nervous plus it's around 70 bucks plus shipping. So I thought I would do it myself. I am hoping to put it onside my stand so I'd like it to not be an eyesore like a 5 gallon bucket. I thought about a 10gallon or 15gallon high tank blacked out with vinyl but i'm not sure about the lid. Maybe I could use a glass top for the tank possibly. My whole point in this is to get peoples ideas of what they might be using as reservoirs, DIY or purchased ones that are reasonably priced. So please let the ideas flow. I appreciate it.
