Hello from coastal North Carolina. I have a pond installation company and have just started my first AP system in my green house. I have 1ft GB and 250 gallon FT. Things are going nicely with bell siphon. Fish less cycling right now...learned the hard way that it is the best way. Question: What is recommended ratio for flood time vs drain time. BtW I use hydroton as my media. I do have plants in the system and they are doing well with the liquid kelp for now. Plan to add fish in another week. They are in the hospital tank still. Awesome group you have here. Thanks.
