Filter System On Used Tank I Bought...how To Use

[Faythee]

I bought a used 125 gallon tank. It has the black plastic rounded corners in each back corner. Big clear box filter with the bio balls in it. I have no idea how to hook it up or use it at all. I have always had HOB. Anyone know of a good link to show me how ? Thanks

Are they weirs with a sump? or like a internal filter setup? Some photos would be helpful.

I'll get some pics when I get home. It has both, and some things I don't even know what they are. She had both saltwater and freshwater and gave me everything.

Here are some pics....needs a good cleaning and quite a project. My husband had to cut some of the pipes off in order to separate the tank and stand in order to move it as the piping was glued. Basically what we need is a diagram of how to hook it up, looks like it was a bit DIY to me, somewhat. Luckily mu husband used to own an irrigation business and can figure this out with somthing to go on. I also need to know how to use and maintain it. Thanks
