You can get a stock tank for an ok price. Im going to get a 500 gallon one for $185. I dont know if thats a good price or not, but its ok with me at least. Easier than dealing with linear, and it comes in grey. I think that would be pretty.
If you dont know what a stock tank is, it is a large container used to water livestock. LIke a huge kiddie pool. Lol. You can get them at farm supply stores, home improvement stores, or hardware stores. Im getting mine at ACE Hardware.
