started new plywood tank over the holiday weekend. the tank will be used to growout my catfish and any other fish that outgrow my other tanks. the tank will be setup on my back patio since it has a nice solid concrete slab to sit on and a cover over it. although it does take up about half of the space out there. this is my first ply tank build and have plans to build another lager tank for the cats since i only figure on them lasting a year to a year and a half in there before they outgrow it. I enjoy building things myself and upgrading so building a huge one from the start didnt make sense to me plus everything i learn from this i can apply to the next one. anyway the tank dimesion will be around 96"x48"x41" or 800g swimming area it will also have a built in filter area of about 16"x48"x41" built into it. the overall outside dims are 120"x56"xaround50".here are a few pics of the progress from this weekend.
