almost ready to begin cycling

• Lettuce has already sprouted!
• Topped off the cocoa puffs.   Cycle time is almost exactly 15 minutes!  perfect. 
• Added an aquarium heater to bring water temp to 80 degrees F to aid nitrification cycling. 
• PH 8.4.  bringing down with "ph-down" to between 6.8 and 7.2. 
• Media should be ready for planting this weekend!
• Going to do fish-less cycling which I learned about (here.)
