The plan so far. Sand is scheduled for delivery on Thursday. Rinse the sand and rock. Get the final touch ups on wire management. Change DI in the rodi system. Then time how long it takes to make 1 gallon of rodi water. This will be Thursday. Friday gets the Apex probes wired up and close to ready for the start. Saturday I will turn on the rodi unit and slowly fill the tank. Time how long it takes to fill and figure out how many gallons of water I have. Then start the nitrifying cycle. With the FritzZyme I will basically follow Dr. Tim's directions for the fishless cycle. Then my thoughts are I should have the ammonia down to zero by the next Saturday. Hope this plan works out. Like the A-Team. I love when a plan comes together.
