I ordered HydroFill ATO from Innovative Marine and only just realized it does not come with a pump. The pump they made for it (to purchase separately) is intended to be external and honestly, I'd rather not have an external pump (aside from having an additional item with fittings pushing water around, I'd need to find room for the pump outside of the ATO reservoir and real estate is very expensive). So what pump would you recommend for an ATO; this one needs to have a regular power plug to plug into the Controller. I was looking at a Tunze Turbelle, but it doesn't look it has a regular power plug.
