Need help choosing? Feature pumps are designed to send water to a feature like a drilled rock or spitting frog. If it's just a small feature with clean water in a reservoir, look at the PondoCompacts or Aquarius Universal 440-2000 range. For larger features and where the water isn't as clean as it could be(!) then you need to look at the Aquarius Universal 3000-12,000 range, or even the Aquarius Eco Experts. Choose a size that gives you the flow-rate you need at the maximum height you're sending the water to - ask us if you need help with this.
