Tank is tripping breaker....

You really need a dedicated GFCI circuit for the tank.

I have one dedicated circuit for the lights and pumps and another shared room circuit for the Apex and ATO, etc.

All tank circuits NEED to be GFCI or you are taking your life in your hands when working on your tank.

Also as per electrical code, a circuit can only run at 80% load. So that's only 12 amps you can use in your whole room.

If your basement is finished, you need to find a creative way to run a dedicated circuit if you're running 1kw of lighting. Trust me, there's always a way. Any decent electrician will come up with 1 or 2 ways it can be done.

Maybe pull back the baseboards to access the wall cavity? That's how all my home theatre wires were run. I'm not saying run a circuit behind the baseboard as that's not to code, but it may help you access behind the wall without cutting holes everywhere.
