"In my process, I stock and grow much like everyone else. The main difference is that I "drain" half my tank every two weeks to another aerated grow bed in a succession of six beds. Each bed grows a different trophic level…"
"Yea, like when the tomatoes are going great guns and the fish load is maxed out but nutrients are low, it's probably too hot to plant lettuce in the rafts anyway so just leave some rafts empty. When it gets cold and the tomatoes get…"
"Yea Ryan, you will just have to kind of trial and error to figure out the right balance. Keep in mind that the balance will vary significantly by season, temperature, fish type, fish feed (protein %) and stage of plant growth. I think…"
"thank u tc. That makes sense, its most likely just going to level off the nutrient level. Not really an assembly line but at least the heavy feeders have the first stab at the nutrients everytime the water leaves the fish tank. But yea, I told…"
"Hey Rupert, I understand the relationships a little better than u think but I don't think I gave enough information. Grow beds (I.e. - bio-filtration ratio of 1:1. Meaning 1 cu ft of grow bed per pound of grown out fish. I was just more curious…"
I was only commenting on what you posted. So are you saying this isn't what you meant to write?
It looked like you were saying 5 gallons for 10 lb of grown out fish??????? That is what worried…"
Ryan, you're misunderstanding the relationships with regard to stocking density...
Stocking density is in the end totally related to your filtration capacity... (and oxygen provision)
More fish will certainly result in…"
"I think u misunderstood. My understanding is that its often recommended to stock one pound of grown out fish per 5-10gal of water. However, its more common to see a pound to 5-7 gal of water. The second part I think u missed is the media beds will…"
You need enough bio-filtration for the fish load. I'm not sure where you got 5 gal-10 lb of fish? 5 gallons of what? Your numbers actually sound a bit backwards to me. I often do like 1-3 (depending on…"
So... I'm new to aquaponics but have quite a bit of experience in hydroponics. However, the question I have is something I havent found in my reading. I umderstand the general rule of stock density roughly being 5 gal - 10 per lb of grown out fish but that generally applies to growing traditional aquaponic crops, which are primarily light feeders. What if i had a media bed that ran tomatoes and peppers (heavy feeders), which would serve as biofiltration and could allow a much higher density of…See More
