As some of you have noticed, I am designing a sustainable solar greenhouse. In my quest to limit the watt draw needed from the solar array and batteries (particularly at night) I have been searching…Continue

TCLynx replied to Pat Chesney's discussion passive aeration of water from the growbeds"Yea, and when the overnight water temps don't drop below 80 F, ya definitely need extra aeration for most types of fish under all but the absolute lowest fish loads."
Pat Chesney replied to Pat Chesney's discussion passive aeration of water from the growbeds"All true, it is complex. But, what isn't in life, eh? I gave up trying to measure DO because I can't afford a meter for that and the chemical test is too prone to error if you don't do everything just right. The best DO meter appears…"
TCLynx replied to Pat Chesney's discussion passive aeration of water from the growbeds"I expect the talk about removing solids has more to do with reducing the BOD (biological oxygen demand) in a low power system but you are right, you remove it and you remove much nutrients for the plants.
How much dissolved oxygen a simple air pump…"
Jason Eaton replied to Pat Chesney's discussion passive aeration of water from the growbeds"Pat, I measured it with an amp meter. The packaging doesn't say what the amp draw is. It looks like your common small cheap plastic bilge pump. I was surprised at the amp draw. One thing a little different about it is the plastic screen is…"

Pat Chesney replied to Pat Chesney's discussion passive aeration of water from the growbeds"I have done work with slow sand filters for 2 years. They are great for purification raw water to safe drinking quality. But, they will stop filtering very fast if there is any turbidity in the water that you don't remove before hand. The…"
halemart replied to Pat Chesney's discussion passive aeration of water from the growbeds"My solution for extending my batteries has been to keep in the C20 range with the batteries, and to use desulfating to break up the normal build up on the plates. In doing this I have bought used batteries about 8 years old,…"
Jason Eaton replied to Pat Chesney's discussion passive aeration of water from the growbeds"Great thread. I measured a small 12v bait airation pump only pulled 0.2 amps at 12v. While the 60g/m bilge pump pulled 3 amps at 12v. Its a huge difference when when your pulling from a 12v battery bank. Running at night with airation only…"
Pat Chesney commented on TCLynx's group Bluegill or Bream Growers"Jon,
I buy my copper nose from Overton fisheries in Buffalo, TX. The owners are marine biologists. They may ship. They may know someone closer to you as well. http://www.overtonfisheries.com/"
Pat Chesney commented on Rob Nash's group Austin Aquaponics"Mike,
One good thing to do is to find fish that thrive in your climate. Catfish and bluegill survive the Texas summer and winter. They are acclimated to our weird weather.
Carp is another very hardy fish. Koi is the name of the fancy carp (Japanese…"
Pat Chesney commented on Rob Nash's group Austin Aquaponics"Hi Rob,
Did your granite come from Marble Falls? I am looking for some. To get to Waco is big $$$$ just in trucking. I am going to co-op with some other aquapons to get a 24 yard truck load to get the price per yard down some. We were quoted from…"
Glenn Dennis replied to Pat Chesney's discussion any documentation on raising bluegill in tanks? in the group Bluegill or Bream Growers"Look at this web site http://www.ncrac.org/Topics/Cultureguide2002.htm
Its a culture guide on BG North Central regional Aquaculture Center at MSU"
Pat Chesney replied to Pat Chesney's discussion passive aeration of water from the growbeds"I appreciate the lively inputs from all of you. I will give an update once the dust settles.
Thanks"
TCLynx replied to Pat Chesney's discussion passive aeration of water from the growbeds"Sounds like you have definitely done your homework. I hope to hear more about your project and what you find that works well."

Brian Cheatham said… Hey Pat, my name is Brian Cheatham. I'm new to aquaponics but it has become my obsession. I'm a student at UNT and noticed you live in Waco. I was hoping to start a discussion with you and learn from some of your experiences since I will be experiencing the same climate challenges. I'm graduating this May and attempting to start a commercial operation immediately after. For now, I have a 250 gallon backyard flood and drain system which I built this fall just before it got cold. During the winter, I have an indoor system set up to save my fish and to experiment indoors. I would love to hear from you and find out local places to find good medium, fish, duckweed, etc. Thanks,
Brian

Carey Ma said… Hi Pat, I'm glad to meet you here.
I am wondering if it is possible for you to post some of your plans/ designs on this site to better help us understand what different systems are composed of.
Cheers
