Have you thought about feeding your fish chopped up Spinach? Would be a crazy idea?
@surfstev hi i use float rafs in my aquaponics system. the iron is available at all plant and some hardware shops here in australia. i have 24000lt or 12000gal of water, i put 1 teaspoon per 1000lt once a month, i do the same with calcium and potassium. the fish trim the roots but do not harm the plants, the fish will also eat the algea which also helps with the conversion of the fish waste
@surfstev Yeah, I don’t see why you couldn’t. I’ve seen some growers put smaller fish in with their floating rafts. I don’t if they would eat the roots or not.
Can you put the floating raft system right in with the fish or are the nutrients too strong for the plants? If the fish eat all the roots can you just prevent them with some screen perhaps?
@GOP4USA It actually worked out really well. The yellowing on the plants has almost disappeared. I’m out of chelated iron so I’ll need to pick up a little more next time I’m out.
How did the iron work out?
@bigt2318 I’ve actually been thinking about doing that very thing.
You could probably put a big nail in the gravel and let it rust to fix the iron problem. Not sure but it sounds right…
yellowing is usually from iron defficiency…try iron chelate
the yellowing may be do to calcium deficiency im not 100% but that may help out
really coming along isnt it. way cool Ed!
liking the shale!
Looking forward to seeing how that chelated iron does.
System looking good…
