"That system looks awesome! I have the same set up with one tote and the green house on the way. My question is, is your grow bed to small for your fish tanks. I only ask that because the book I read from Sylvia Bernstein suggest a 1 to 1 ratio when…"

Tilapia as 'graisers'
I was wondering how well tilapia do as an algae controlling graiser. I'm talking about the surface growth.
ModeratorVlad Jovanovic replied to Beth Medeiros's discussion How many fish do I need?
"I wouldn't worry much about that George, since most plants need way, way more Mg than Fe. It's super-duper-ultra unlikely that you've 'hurt' anything yet

ModeratorHarold Sukhbir replied to Debra-ann Phipps's discussion Plants all died
"Hi Debra,
I see from your videos the drain lines from the GB's are near to the base of the beds, which looks(appears to be) like about 4-6 inches below the top of the bed. If the drain lines are indeed set at a "close to base height",…"

External Bell Siphon Schematic
"Ok with the 90deg fitting turned it all makes sense including the vacuum break that was throwing me. So using the Vacuum break obviously sets the water level in the grow beds. "
David - WI replied to William J Silverthorn's discussion Water Pressure Puzzle"If you want to have any significant water pressure to feed the grow beds, the fish tank would have to be up fairly high... if you set it up like the sketch above anyway.
It takes a little bit more than 2' of height to make 1 psi of water…"
Pat James commented on Pat James's blog post Swimming Pool System"Jim, Yeah, I want a bunch to use as scavengers, and insect control. I live in prime mosquito country. But I'd rather use the majority of bio load capacity for something I can eat.
Which brings up an off the wall thought... Has anybody ever…"

I have not tried the salt treatment as yet. If I have any fish left by this weekend, I'll take a stab at it.
Do you happen to know the ratio of salt to water and the time necessary to 'dip the fish'?"
Paula Costa replied to Roger & April Frederick's discussion Anyone using Growstones?"Hi Matt, Growstones don't disappear or disintegrate with handling. They are large enough and will remain a large stone or aggregate with all its physical properties, long after many years of usage. Yes, they will produce some…"
Larry Alesi replied to Beth Medeiros's discussion How many fish do I need?"You might want to try a nutrient calculator like the plant people use in the Aquarium hobby. http://calc.petalphile.com/
I use this for my planted tanks and along with the plant deficiencies chart that was previously posted. It's important to…"
Chelsea Brannan replied to David L. Eisenbrandt's discussion Water wheel powered air pump"Interesting articles Paul! Thanks for posting those."

Bell Siphon.
"So by raising the tube you can manually break the siphon?
Is this a method of setting the water height without changing standpipes?"
George replied to Beth Medeiros's discussion How many fish do I need?"Vlad, I follow you. Unfortunately, by weight, so I added almost twice as much magnesium as iron, 10% / 6%.
Thanks. "
ModeratorTCLynx replied to Roger & April Frederick's discussion Anyone using Growstones?
"As long as the pea gravel in your location is large enough and not made of limestone. I have to warn people constantly that "pea" gravel describes shape/size but doesn't tell what kind of rock it will be. In many places if…"
ModeratorVlad Jovanovic replied to Beth Medeiros's discussion How many fish do I need?
"George, When you say "at about the same rate as iron..." do you mean by weight of the powder/salt, or by percentage of iron/magnesium contained in the powder/salt?
Epsom salt (or magnesium sulfate heptahydrate... MgSO4-7H2O...is about…"
Jim Troyer commented on David Schwinghamer's group Arizona Aquaponics"@ Stephanie:
Nice filter design... Interesting to note that your grow beds are flowing better.
If you want to add a filter medium, the blue swamp cooler pad works great. The worms can crawl through to clean it so you'll…"
