I would have one for each, I will be using an air pump 75 for bottom drain + 150 for the nexus but it really depends on how much media you have in your nexus. For example if you have 50-75 litres of media you would only need to run a 75 air pump. Hope this helps

Depends to an extent on how deep the pond is but I run a single Hiblow 80 on my wildlife pond which is 2200gallons and has an N200 on it.
