In my set up show in the OP of this thread, the switches are for the pumps, not the Love controllers. The Love Controllers are on their own.
You can use whatever controllers your heart desires I would guess. It's all the same electrons flowing in your wires. I went with Love for the simplicity and low cost. Hard to beat the price and simplicity of the Love controllers. They work and do so for a fair price. The Auber stuff is well priced as well so I can't knock their controllers either. Either way, you'd be in fine shape I reckon. That said, the Loves have handled a fair amount of abuse in terms of washdowns, etc. You should really probably have them in a waterproof enclosure but I got lazy and didn't do so. I've been impressed with them and the amount of abuse they can withstand.
