This may be too late for you and may or may not be applicable, but here is one thing worth considering when wiring the pool. As I type this, I realize that you were asking about an above ground pool, when I have an in-ground pool. I will add this comment anyway, as someone may find it useful or may wish to comment on it.
Our in-ground pool has two pumps. The main ( filter ) pump and a pump for a Polaris ( robotic pool cleaner ). The previous owners of our house had each hardwired to its own 2 pole 20 amp gfci breaker. They also used the breakers as the power switch. We had an electrician come out to upgrade the wiring and disintegrating conduit for the pool system. He put both pumps on the same 2 pole 20 amp gfci breaker and added 2 pole switches to control the pumps, rather than using the breakers as switches. Here is what you ( or someone else might find useful ): He interlocked the switches such that Polaris cannot be turned on unless the main pump is on. Running the Polaris without the main pump turned on, while probably not a safety hazard, can damage the Polaris pump motor as it depends on the main pump for its water supply. As a matter of fact, the documentation for the Polaris warns in the very first paragraph that running the Polaris pump without the main pump also running will void the warranty on the Polaris pump.
The electrician ran the power from the breaker to the main pump switch. From there, the power goes to the main pump and to the Polaris switch. That way, if the main pump switch is not turned on, there is no power to the Polaris switch, so it cannot be turned on accidentally.
