I did a water change several months ago due to excessive ammonia. I put the water into a container, added a gallon jug of hydroton with an air line inserted to see if I could preserve and use the…Continue
I have a 65 gallon filter tank that I recently switched from swirl to radial flow because I felt like the swirl wasn't catching enough of the solids. The RFF definitely catches lots more of the…Continue
I read about adding nitrogen to soil gardens but there aren't any suggested levels for nitrogen in the form of nitrates. If I want to use fish water to fertilize my gardens what level of nitrates…Continue
"I've heard of it, I think in one of Sylvia's videos but I have never worried too much about it. I've tested it but didn't make any changes. There are 2 schools of thought for controlling PH, carbonates and hydroxides. Sylvia…"
"You don't need any special water for germination. Seeds have plenty of nutrient for the initial growth. I do use the system water because it's convenient and I don't have to worry about when to switch over to system water.
"Frank. Don't let one persons opinion affect your enjoyment of this forum. Every once in a while someone will try to market something on here. Just ignore it and follow what you like. I just wish it was more active like it use to be."
"Wish I could redo my space. 1st I'd double the size. I'm curious too why you chose not to use bell siphons Yaacov. I'd stick em right in the middle and drain from all directions. I've recently seen a video of a guy who just has…"
"I have the same setup and beds, even the same block supports. My sump is 200 gallons and in ground. 300 gallon FT. A single feed to the beds will be sufficient. As I said before it will be difficult to feed the beds evenly from all corners/sides.…"
"Welcome Frank. Not sure what you're referring to when you asked how many holes to flood beds. When I first started I put water in at 4 points on the beds but it was hard to regulate. I've since switched to a single inlet. Flow can be…"
"Water level is a biggie. On more than one occasion I've had a catastrophic leak in my system but with a sump the fish tank stayed full even though the sump was empty. The sump is also a great place to add nutrients. The sump will give you…"

I did a water change several months ago due to excessive ammonia. I put the water into a container, added a gallon jug of hydroton with an air line inserted to see if I could preserve and use the nutrient water in my outdoor gardens. Today when I measured the nitrates they were off the scale with a ppm of 1330. I kept diluting the water until finally getting the test water to change from dark red to just red...8 to 1. Of course the ppm's dropped to 210. Is there such a thing as too many…See More
"It's been a while since you posted. I'm surprised no one has replied. If your ph is 7.4 it's too high for good plant growth as you probably know. I have a similar problem and similar system. I use muratic acid to lower ph in low…"
"Congratulations Yaacov. Will the beds be flood and drain? What type of media (if any) will you use? As for lighting I wouldn't worry too much about LEDs initially due to the cost. Florescent fixtures will work fine until you better understand…"
"I have pics in my photos on my page. It's more of a concept than design. There's no doubt in my mind that this is how I would go if I did it again. The design shows multiple FTs but can be done with one. Not sure how familiar you are with…"
"Right now I have okra, tomatoes, egg plant and peppers in the greenhouse. I'll switch to cool weather plants for the winter. Just grow for fun and personal use. Don't have much on it but you can check out my Facebook page "Fish House…"
Jeff I'm not a frequent visitor here as of yet but as my garden develops further I will be in a position to contribute as everyone's experiment is unique. I built a permanent greenhouse that incorporates the concept of the Walipini ( I have a 5' deep poured foundation ) with a more functional roof design to catch as much light as possible. I set he design 15* to the southwest to improve winter exposure. It's set at 45* spans 20 feet and is made of 18mm double wall acrylic panels. The north face is at 65*, spans 18' and is standard roofing. I ran a 100 amp service to the building and have my own well. I've built my medium grow beds and have the material to Build and play with some grow towers. My project today is to complete my swirl filters and start to get the plumbing going? You seem to have a lot more experience. What made you try aquaponics, what are you growing and what type of setup do you have?
What kind of Tilapia do you have ? I am looking for Nilotica, but also some Blue to set up a couple pairs for hybridizing. These will go into house tanks for control. Or as much as I can get with Tilapia.
I am planning a hoop house, with a couple of totes, and about 4-6 inverted ones for grow beds. Where did you find your totes? I havent located any food safe ones yet.
Wow! that's great, are you using your greenhouse now? There are others selling Tilapia in MI on craigslist. They sell for $1-2 each around here. I want to buy from a certified fishery, because of the legalities. I don't heat the basement side of my house, its like 36. My greenhouse is 32. I'll wait til Apr when the greenhouse is 45-50. I have two 275 gallon ICB totes and plan to start with 60-70 fingerlings and hope they don't breed. Also have an old 7x7' hot tub that I'm going to put in the ground and use for a sediment tank. I'm going to post my plans soon.
Hi Jeff, I'm learning how to use this forum, looks like a good place for info and questions. There are several fisheries in MI that have Tilapia planting stock. I found this list, but not sure how current it is:
I'll be looking to buy Tilapia fingerlings like beginning of April. I have emailed Mud Lake Farm, Zeeland, MI, but no response yet. Are your Blue Tilapia pure breed stock? I plan to raise the Tilapia April - Oct and shut down for the winter. Have you harvested some of your Tilapia, I'll bet they're good eating. I'm 6 miles from lake Michigan, near Saugatuck, time to get snow blowing done over a foot of snow here!
Currently I'm running a 4" flex duct to a small hair dryer into low tunnels over my grow beds. It keeps the air in there about 73 %RH during the day. There are a couple of lights in there too, so I might be okay with just a little fan (no hair dryer).
Your idea could work. You'd need to use copper pipe I think, and make sure the water got really cold before you recirculated it. Probably glycol would work better. Really creative. I like it!
Ok will do. I don't know if this is related, but there is currently an issue with my hosted server, so I won't be able to do it until it is resolved by the hosting company. Will let you know as soon as its done.
