Reservoir construction

These diagrams detail the layout of the reservoir for use with an external pump. Many larger submersible pumps can be used externally by removing the detachable intake grates - beneath which you will usually find a threaded intake fitting. If you are building the 4" system or plan to use a submersible pump, you will not need 6" system. The only difference would be that you no longer need to drill the hole for the thru-hull fitting as you will no longer be using it. In this case, you may elect to pass the pump line through a hole you can drill above the water line or in the lid of the reservoir. I strongly recommend using an external pump as it will keep the nutrient temperatures cooler since its heat will be dissipated outside the reservoir. Use lots of silicone sealant where the thru-hull fitting passes through the reservoir.

When cutting the holes in the lid for the chamber's drain fittings to drain back into the reservoir, you will need to space them at least 7" apart if you are using 6" chambers. The spacing you choose ultimately depends upon the configuration of your garden and the number of chambers you plan to use. You'll be cutting the same size holes in the lid and in the reservoir as you did for the drain fitting on the chambers. (see step 3.)
