All about ET40

Virtually all hydroponic systems will require an air pump of some type. The nutrient reservoir must be oxygenated to maintain maximum efficiency. If you do not want perfect plants what are you doing here? Don’t worry, you’ll have your hydroponic system set up very soon. my site is an excellent resource for this.

  1. Figure out the length of air tubing you need for the air stones to sit in the reservoir where you want them. Leave a little extra tubing- you don’t want too much because air loses power over distance.
  2. Put a hole through the side of your reservoir if you want your lid to seal. Put the hole close to the top where water won’t spill out. The hole is where the air tubing goes through.
  3. Put your tubing through the hole you made before connecting the pump or air stone.
  4. Connect any T connectors you plan on using. T connectors connect two air lines together to aerate two separate stones. One large pump can aerate many air stones in one reservoir or provide all the oxygen to many reservoirs. I use small pumps for each reservoir so all my eggs aren’t in one basket.
  5. Cut your air line before it meets each air stone to put in check valves. Check valves ensure you air pump does not siphon water in the event of power loss. Siphoning water into your pump could break it.
  6. Connect your air lines to your stones and place them where you want them. I like heavier stones that stay in place at the bottom of the reservoir. If you have multiple air stones, spread them out so your entire reservoir is oxygenated.
  7. Now is good time to hang your air pump if you plan to do so. Pumps can be noisy and sometimes give off a loud vibration that gets really annoying. A hanging air pump should be a quiet air pump.
  8. Connect the other end of your air tubing to the little connector coming out of the air pump.
  9. Plug in you pump and oxygenate that reservoir! Your hydroponics system is almost ready!
