You are in good hands with Troy, if you need any ideas about linking tanks or drains together you can see what we've done here.

We use whats called a stock tank for our sump and another one for our fuge ( you can find them at any Agway or a feed and grain store) they are made to be put in a field so cows or horses or whatever can drink from them, they are very rugged and come with a bulkhead fitting already, so connecting your pump to it will be easy. They also come in different sizes, we use a 100g for our sump and a 70g for our fuge hth.
