Procure two 55 gal. plastic drums (food grade). Cut drums in half, lengthwise, with an electric jig saw (follow the line left by the casting form). This gives you four trays. Drill five rows of 3/8" holes on the bottom of three of the trays. The holes should be 2" apart and should be staggered from row to row.Fit the bottom tray with three 2" exit pipes using 2" Uniseals, (Aquatic Ecco catalog) much cheaper than bulkhead fittings.
Make a four tier support rack out of 1.5" or 2" PVC pipe (sch 40). You will need 2 lengths of pipe, 12 ea. 90 degree elbows and 21 ea. "T"s. Make a supply distribution manifold loop out of the same pipe as above and supply it with 15 to 18 hundred gal/hr. Use plastic zip ties to strap down the manifold and to hold the trays level. Install a 14" wide plastic grid to bridge the holes and hold the media from clogging the holes.(I use flourescent lighting grid pannels.) Cover the grids with 3/4" thoroughly rinsed lava rock and plug it in and start the colonization. The benefits will start showing in a week to ten days. |
