Would the 150W be enough? The power supplies say "100-240Vac 1.8A, 50-60 Hz)

I'll totally admit, when it comes to electricity....I know absolutely nothing lol.

If the pump is a waveline, contact them. They replaced mine with the new style power supply. See my thread on the product review page for the pics of the differences.

That's the input, read the output specs. Should be 24VDC @ X amount of amps. I believe the 2640 pumps are rated at 85W or 3.5Amps so to run one pump you'd want a 100W supply, for two pumps a 200W supply. You can always go bigger as well, just not smaller as you'll burn it out.

Here is a pic on the back of the power supply.

Ok so you need a 24VDC with at least 5.0A to match the existing. So you could either run one off the 150W I linked previously or run two off a 240W like this

After the acid bath, I let the rock dry out for a couple weeks. Now on to aquascaping!

I like this final layout but keep in mind that I didn't have any fijicrete, so the arches are temporary. They are just holding things together. I am going for three islands. Mind you, the arches are starting to grow on me. The way it sits, it's about 70" long. Should fit well in the temporary 79" long tank.

They are based off a big rock at the bottom, with a 3/4" PVC support that I drilled into the rock. This allowed me to brace most of the pieces so that they are stand-alone structures. There's a couple pieces that will need to be fijicreted or zip tied into place.

Then cut the cord from the old adaptor(s), the one that plugs into the controller(s). Strip wires same as above.
