Getting my feet wet in Aquaponics, still learning little by little. I have a 360 gallon tank with 3 growbeds of 100 gallons each. At the moment I have tomatoes, peppers, cabbage, corn, cilantro, strawberries, onions, eggplant, lettuce and watermelon. The tank is fully cycled and I have tilapias on the tank, although I need some more I think. I am using a little of Maxicrop until my system matures, the ph is 7.2 and using lava rock that a friend gave me for free. The growbeds are IBC tanks that I got it for free through my job.
