Is alright to run a outdoor extension cord to a pond. The cord runs
about 15 feet to a gfi . And can I place the cord underground..about 6
inches. Dont have the cash right now to do it right.

UGF Romex is pretty cheap. Putting it deeper is just more labor, which
is free if you do it yourself. PVC conduit is cheap too.

If its the electrical connections at the ends that put you off, many
of your friends & neighbors can advise you... collect everyones advice so you
weed out the bad ones. Or buy a Sunset/Ortho/etc electrical wiring book.
