6. Next, spray paint the outside only of the clear reservoir bin, to make it light proof (prevents algae). Spray several coats and use the entire can. Do not spray the inside of the bin.

7. Set up the tray on a sturdy level support, (it's final resting place). Fill with 6 gallons of water. Place the airstone in the bottom of the tray, connect to the air pump, and plug it in to test it. Important tip: Place the air pump higher than the reservoir to prevent nutrient from backing up into it.


  


8. Next, add your favorite nutrient solution to the vat. If you are using GH Flora Series (recommended), add 6 tsp. each of the Flora Grow, Flora Micro & Flora Bloom, (one at a time, in that order). Adjust the pH with a test kit (more on this and ordering info in the Tips 'N Techniques section below).


9. Next, float the styrofoam raft on top of the nutrient solution. You want it to ride at the very top, so add more solution if your bin requires more than the 6 gallons.
