To defeat or "beat" the 7th gym leader in Pokemon sapphire there twins and they have a solrock and a lunatone to beat them I suggest about level 40-50 water types.

After you beat Norman in Sapphire, head next door (the house to the left of the gym). There, Wally's parents will give you HM03 (Surf).
