Thank you all for joining my group, I hope to do a lot with all anyone interested. Please tell me any event suggestions you would like us to do.

... and as for making changes to the system, I'll never stop changing, adding, improving, working, extending, and 'fixing' it.
It's a constant shame when there's no room in the grow beds to plant anything.
The DWC bed is constant height.
Except... I use a small very cheap fountain pump to move water through the solar panel in the winter months. It used to sit in the bottom of the in-ground fish tank, but then I had a brainwave. Why not put the solar panel pump in the DWC bed. It's higher, and closer to the solar panel, so I'll get better flow through the solar heater. Brilliant idea. It decreased the head height and shortened the lead pipes to the solar panel. The result was a noticeably better flow rate which makes for a more efficient heater.
The very small amount of water that the solar panel pump moves is irrelevant in normal use, because of the volume of the DWC bed and the regular inflow of water from the system. But when I turned off the incoming water flow the little fountain pump just kept on chugging away, little by little. The other plants in the bed didn't care about the situation, but the lettuce certainly did. This surprised me, considering that the roots on the lettuce are a couple of feet long and would still be in the water.
As Michelangelo said: "I am still learning."
Hi John: nice to hear you too are still making changes to your system.
I was surprised to hear that your DWC bed is not constant height.
How is the water level set in there and do you allow it to rise and fall regularly?
Thanks for sharing
all the best,
Radial Flow Filter Upgrade
I decided to raise the RFF so that it would be easier to empty the contents in to a 5 gallon bucket to be used in the garden. After turning off the water I dismantled the filter and built a nice 20" frame for it to stand on. Lovely. I was worried that the extra height would be too much for the pump to overcome, and it is a slower flow-rate, but all seems well.
What I didn't realise what that during the hour or so that I had the water off, the solar panel pump was slowly emptying out the DWC bed. It's a really slow pump, so I didn't pay any mind to it. The good lady came out while I was admiring my new RFF stand and said "What's wrong with the lettuce?" Whaaaa? It appears that lettuce takes a very dim view of not having their roots in water.
Turned the water on pronto and next day the lettuce was back to normal. Whew!
Congratulations, you have Koi.
So I haven't posted in a while, we were working on an expansion for the aquaponics in January. Then Josh was in a motorcycle accident in February, broke his femur in his left leg and totaled his bike, other than that he's fine. So the expansion is just going to have to wait a bit longer.
Last year I'd gotten a bunch of water hyacinth, and decided to pull it all out cause i was feeling a bit guilty about harboring an invasive species in my back yard. So I was looking at the roots and saw these little round things stuck to them. Any idea what they may be? They don't look like the snail eggs that I've seen before. My mosquito fish are live bearers, and I'm pretty sure that bluegill and koi don't lay eggs in the roots of plants. I threw a couple of the plants into an aquarium i was going to use to raise red cherry shrimp for now just to see if anything comes from it. Any ideas?
Re: your worm bin. I have found the best worm food to be fish waste, which slowly accumulates in my sump. I remove it with rectangular fish net, and store it in a plastic jug. My worm bed is a styrofoam ice chest. I have several sponge filters on the surface. I pour the fish waster on top and cover with the foam filters.
I keep the worm chest in my office. There is not much odor and the worms like the indoor temperature.
Hail storm and new seedlings.
Pea sized hail did some minor damage to the garden and finished off the remainder of my seedling that hadn't been planted out. That's OK, I didn't have a use for them anyway. Started some new seeds on paper in plastic bags. 2 days and the cucumber and basil seeds were ready to plant. The coriander is being somewhat more stubborn.
About your worm bin and fruit fly issues. There's over 500 species of fruit flies in the world. I am sure right now you could do without one of those species...a few things could be going on... All food matter added to a bin should be buried in a minimum of 2" of bedding. That means surrounded by 2 inches of bedding top, sides & bottom. Entomologists studies show that the gases given off by degrading vegetation (fruit) is dissipated/dampened some by this added bedding and fruit flies will not penetrate 2" of bedding to get at a food source. You don't want the flies getting at the food sources because they will lay eggs there and then you'll have an establishes fly population that is difficult to get rid of (which sounds like where you are at right now). All food that is destined for the wormbin should be protected from any chance of flies landing on it prior to going into a bin. Flies land and lay eggs and then if that food is added to the bin, the hatching maggots will think they've just emerged in "fruit fly heaven". Keep food matter in a container before adding to a bin, or in the freezer before adding it to the bin (to kill any eggs and/or flies).
The design of your bin could also be an issue in dealing with fruit flies...
So how do you get rid of the fruit flies? A simple way is to just start over. Start with the same worms but new bedding. This may also be the most sure way if you have done any "stirring" in your wormbin, since stirring will just mix the establishes fruit fly eggs/larva in the bin deeper. A wormbin should never be mixed/stirred.
If the fruit flies have not been there long and you can pin-point the exact food source the fruit flies are invading for, remove that. Then put a jar lid or other shallow container in the bin, set on top of the bedding. Add some vinegar or wine to the lid. Fruit flies will be attracted to the lid & dive in. Dump out the accumulation and repeat. You'll need to keep this up for the time it takes for eggs to hatch and change to adult form, and average of 7-11 days. (I'd keep this up as long as the flies keep landing in the lid). Keep in mind that fruit flies can live an average of 20-40 days depending on the species and environmental factors. The sooner you get on top of this, the easier it will be to stop the infestation.
Redworms can consume 1/2 their body weight in food matter a day. 24 redworms does not weigh much (about .384 of an ounce, using the average of 1000 redworms weighing in at 1 lb.). You do not want to get way ahead of your redworms by adding lots of food. Food that sits in large amounts and is moist (worms need moisture) begins to ferment, and then an anaerobic process starts (which will serve also to attract fruit flies).
Once worms are put in a newly prepared worm bin it take an average of 1 - 3 weeks before they settle in and begin their normal eating and reproducing habits. During this time they need to be fed lightly, so you do not get the bin way too full of food. Redworms are secondary decomposers. They are in a symbiotic relationship with other beneficial microbes that also live in your bin. The microbes start to work on the food you add to the bin and then the redworms get to work after that. Once you notice the food you have added to the bin begins to look like fine coffee grounds (these are worm castings), it is time to begin to feed more, since your worm population is now "up to speed".
If you have any questions about dealing with your "herd" of worms, & the infestation, I'll gladly help out. We run a worm farm, and we are always glad to help out a fellow aquaponics enthusiast. Go ahead and send a private message if you wish. In any case, I wish you the best in getting on top of this fruit fly issue, and the best with your redworm bin!
@ Arron: good to hear! I have more fish if anyone needs them.
@ Matt: not sure if the tubes are a good thing or not. I had a couple of fish in the aquariums get just torn up by getting ripped against the side of the tube as they darted in there to avoid an attack. The worst one lost 3" of skin on both rear flanks and his his tail never grew back. I put him (Stubby) in the pond, haven't seen him lately however. I removed the tubes and move fish when they can't play nice. Sometimes they get moved all the way to the frying pan...
@ DJ: I agree with Matt, don't waste your money. if you want to kick start your system come and get some water from my system. I have about 3000 gals. 480.257.5214
