Patience is a virtue ... even in aquaponics

[Bob Vento]

I am pleased to announce progress on our system. This week I managed to buy, rinse and re-rinse lava rock for  2/3rds of our grow bed and tomorrow will be buying 10 bags of Stalite for the top grow bed layer.

The water has been cycling for a week now and has cleared nicely and I think I may net some local canal fish on Sunday to put in the tank to see if they can survive before purchasing my mating tilapia.

I am still not clear on when ammonia should be added to my system? Anyone?
