Pump for Hydor ATO
so i'm waiting on my Hydor smart level control ATO system to arrive. i chose it because of its affordability and the lack of float/moving switches. can someone recommend a good pump to go with it? The height that the water has to travel is probably in the neighborhood of 3-4feet directly into my display tank since i don't have a sump. something adjustable would be great since i wouldn't want a sudden splash of water (or is this too OCD?). also, should the water go through one of those airline pipe or something bigger? Thank you very much.
