Drain lines placed above the reservoir will spill water back into the reservoir, creating varying degrees of oxygenation.Īerators are a lot more effective at oxygenating the water in your system. In recirculating systems, a drain line from the grow chamber returns nutrient solution to the reservoir. The water in your hydroponic system is oxygenated in a couple of ways. No matter what system you use, your plants need oxygen. In a hydroponic setting, plants get most of their oxygen in the form of dissolved oxygen in the nutrient solution. Plants absorb oxygen through their roots. The Best Aerators for Small & Medium Hydroponic Systems Works as a submersible, sump, and inline pump.This pump will empty out reservoirs, and small ponds or pools quickly. The 250GPH model uses a 1/2″ fitting while the AAPW1000 uses a 1″ fitting. One big difference is the sump pump fitting. It has all the same features as its 250GPH little brother. This pump has a maximum head height of almost 12 feet, and can still pump out over 400 gallons per hour at a 9′ head height.Īs you may be guessing, this pump is for larger-scale systems. If you need to pump out a serious amount of water or reach the top of tall vertical systems, the AAPW1000 will provide the power you’re after. Works as a submersible, inline, and sump pumpīest Large Multi-Purpose Hydroponic Water Pump.Recommended for reservoirs up to 25 gallons.I keep an extra 250GPH pump with the bottom draw adapter just for draining reservoirs. This is super handy when it’s time to empty and replace the water in the reservoir. This adapter turns your submersible pump into a sump pump that can pull every last bit of water out of a reservoir. This feature is ideal for hydroponics since nutrient solutions are made with nutrient salts.Īnother advantage to the Active Aqua line is the bottom draw pump adapter (sold separately). Speaking of parts, the AAPW250 comes with a ceramic shaft rated for use in saltwater environments. The pump is easy to take apart for cleaning, and there are a lot of replacement parts available for them. The next step up from the AAPW160, this pump comes with additional fittings that can be used to turn it into an inline pump that sits outside the nutrient reservoir. Hydrofarm Active Aqua AAPW250 250GPH Water Pump Recommended for reservoirs up to 15 gallons.The pumps come with a 1-year warranty, but you’re going to get way more than 1 year’s worth of life out of em! Try doing that with the ultra-cheap competitors.

Most other manufacturers on Amazon don’t do this. Why? Because this manufacturer publishes full head height charts for all their pumps. You’ll probably notice all the pumps I list are from the same manufacturer. As the name suggests, submersible water pumps go in the bottom of a nutrient reservoir and are surrounded by water. It’s handy to use a sump pump when you want to completely remove all the water from a nutrient reservoir.įor smallish scale hobby hydroponics, submersible pumps are what you’ll mainly be dealing with. Two of the pumps listed below can operate as an inline, submersible, and sump pump by changing out a couple of parts. The Best Hydroponic Pumps For Small & Medium Hydroponic SystemsĪ quick search will return results for thousands of different water pumps.įor hydroponic systems, you’ll mainly be interested in inline and submersible pumps. A pump will move the water throughout the system while an aerator keeps the nutrient solution clean and oxygenated in the nutrient reservoir. On the other hand, if you’re building a nutrient film technique, ebb & flow, dutch bucket, or vertical hydroponic system, you’ll want to look for a pump and aerator that fits your needs. Jump to Best Aerators for Hydroponic Systems Basic deep water culture systems don’t need a water pump. If you’re building a deep water culture system, jump down to the aerator section. For the money, these items are hard to beat. ![]() I think they’re the best hydroponic pumps & aerators you can invest in as a hobby gardener. Below you’ll find products I use in my own systems. Sizing and selecting water and air pumps for hydroponic systems can be tough if you’ve never done it before.
