Its up to you but if you go to a local pet store for 20eur you can have a perfect 1000lph pump, if you dont want spending 32euro on the ebay one/3000lph/.
What power spindle was that with? Mine is 800W.

I'm actually leaning more towards using the separate pump and container as I'm not really that convinced the screenwash pump will last very long. I had a brainwave today on the tank. I've got a tall small footprint plastic food container that could be a good tank and I can make some bulkhead mounting pipe fittings using hosetail connectors and a nut and washer.
