What happens during electrolysis of potassium aluminate?

I am toying with the idea of a koh solution using aluminum electrodes that have been nickel plated before hand. I would clean the nickel oxide off of the anode periodically using a dilute acid solution then plate more nickel on the aluminum electrodes. The aluminum would be aluminum foil, and i would hope that the nickel would block the koh from attacking the aluminum. But i am curious what would happen if the nickel layer is breached and the koh is allowed to react with the aluminum. If I am correct, potassium aluminate and hydrogen will be formed. I am unsure if the addition of potassium aluminate will affect the electrolysis or if it will just act as an electrolyte. I would have multiple anodes and cathodes so i am curious is the loss of one electrode would destroy my solution. or if i can just replace it and not worry.
