Aquaponics 101 Part Three: System Design, Continue

[mbrown]

in most backyard systems, the biofilter is the growbed, this is where most of the bacteria live that perform the process of breaking down your ammonia to nitrites, and then to nitrates
add some red wiggler worms in your growbeds to assist with breaking down solids..
easy peasy HA

Then is the bio filter necessary? My fish seem to be doing well, now, I did have a few die for what ever reason. Could have been me trying to change pH and alkalinity at the same time. I am going to try and add the worms and skip the bio filter, add more aeration and continue to add the liquid seaweed with chelated iron. Also I will add 12 more fish, this will give me 28 commit goldfish in a 300 gallon tank that works on a overflow system so the level only changes 4" total drop.
