I am interested in learning about hydrophonics, and have seen a few comments about using fish pond water as a nutrient filled source of water for the plants and also as a way to remove harmful elements from your fish pond. Sounds like a win/win situation to me. Anyone have any knowledge, or where I might find some info?
What you are looking for is "aquaponics" invented by Mark R. McMurtry at the U of N. Carolina some time back. Here is a working example of his system, invented by Travis Hughey called barrelponics. I have lost his site with all the information on how to make these things, but here is a working example at a college built by grad students: http://www.yahooka.com/forum/farmers-lab/151150-barrelponics.html
After I wowed over it for awhile, I realized I was on a cannibis growing website, but the comments are concise and to the point.
Google Travis Hughey barrelponics should get you some blueprints.
Thanks Poetinwood, but I think I'll wait on that. Looks more complicated than what I want to tackle right now. Good for future reference though. I guess I'll just plant me some maters the old fashioned way, but maybe water them with pond water.
Dgal: A lot of us here drain off our ponds very regularly and use the water on the plants. The fish need frequent partial water changes for better health and what I personally do is pump off the bottom where the fish waste is and send it throughout my garden. I also have a bio filter and have to clean it weekly and I have that attached to a long hose and water plants in another part of the garden.
Mothermole, I had a very small pond (about bathtub size), but had a leak, so I took it out and built one that is about 8' x 10' x 2 1/2' deep. I did it just over week ago and still setting everything up. I am working on the waterfall today. It is a beautiful day here. Clear and 78 degrees right now. The weather should hold for the next few days, so hopefully, I will get it pretty well finished. I put the fish in about five days ago and they seem to be thriving. I'm sure they are enjoying the extra room. Right now, I only have one 10" koi and two goldfish. I put the plants in it yesterday; floaters, submerged and a couple of bog plants. I have more coming when they will start shipping around April. I was amazed at how fast they are bringing down the ammonia level, not that I let it get that high. I am doing partial water changeouts every few days.
I am experimenting. I cut down the old preformed liner and trying to use it for a base for my waterfall. We'll see how that works out. I'll try to get some pics later today.
For 2 years I planted water cress and got so huge that it took over my pond. did i eat some? Yes plenty of it , Dh refused to eat the first year but he ate last year. we had plenty of it--- cooked with balsamic vinegar. I only use peroxide, baking soda and salt . So far i had not had problem with my fish. Knock on wood!! LOL!!!. Belle
Belle, you should be safe with those things! I have one large water lily tub that I never add anything to (not even fertilizer) and I grow lush mint along the one side. Fish "emulsion" is great for plants... I dont even grow my water plants in soil, just let the roots suck up anything in the water! :)
You WOULD have to worry if you were using copper agents, etc, which control algae...
Not many people put their medicines directly into their ponds but into a "Medical holding tank" because most medicines cost a fortune and ponds are too darn large. However some treatments have to be done to the pond and the fish and I wouldn't eat anything watered with that water. BUT, on the other hand when you treat your pond completely with medicines, part of the treatment usually states you have to do aggressive water changes between treatments. A few water changes and you should be fine.
Thanks Jeanne, I did get quite a bit done today on the waterfall. I got the main structure set up and everything "glued" together. It should be set by tomorrow so I can test it out. I love to hear the water falling on the rocks. I still need to stack rocks around it for asthetics purposes. I'll try to think to get some pics tomorrow.
