Running a deep water culture system? Then why not check out Plant Magic DWC nutrients, which are formulated specifically for the job. And don't forget that adding Silver Bullet to your reservoir will ward off root diseases for up to 5 weeks, keeping your plants growing sweetly during even the most diffcult periods.

Using the Charles Austen Air Pump Kit

Connect the L-shaped piece of rubber tubing to the air outlet point. Fit the manifold into the rubber tubing and secure it in place using the two provided clips. Connect lengths of air line tubing to each manifold outlet and insert the barbs of your air stone into the other end of each length of air line.

Insert your check valves into each air line by making a cut in the pipe. The black end should be joined to the air line tubing coming from the air pump and the clear end should be fitted to the air line that moves on out towards the air stone. This will prevent back any water siphoning back towards the pump, should the unit be accidentally switched off, or in the event of a power failure. Even so, it's still best practice to position your air pump in a raised area, using a stand or shelf, etc., so that it sits above the waterline of the pump’s destination reservoirs or system.

Never immerse the pump in water!
