Scored free...now what to do with it???

I picked up this 20ish? gallon homemade sump. It was used in a salt setup. I understand how it works, what I dont understand is the gap in the dividers...whats the point? Also, I thought sumps had to be somewhat deep, this one is 36x12.5x12.5 (LWH), to achieve the most water, am I wrong here? Ive never used a sump hence why i ask. Also, what size tank can I realistically use this on?...Heres a couple pics of it, has who knows what in it, it needs to be cleaned bad lol...although the calcified corals were kinda neat

That's a odd looking sump, not familiar with salt water sumps but height doesn't really matter to much. Height is better with wet/drys but with sumps as long as the media is submerged it fine.

Custom fit a sponge or shove filter floss into the gap between the dividers for mechanical filtration.

Looks like you need to buy a gallon or two of cheap white vinegar. Remove all of the deposits that you can then fill the tank up with vinegar and water and let it seep for a while. A pump to keep the vinegar and water circulating will reduce the amount of time it takes to dissolve the deposits.
