"Algae is a part of start up. Seems to happen to pretty near everyone. Sunlight is #1 culprit of course along with too many nutrients for the amount of plant growth. Having no patience I wanted the pea soup gone asap so I built a 30g (2500g system)…"

"Greetings. It has been my experience that soon after you get your pH down under 7 and you get a critical mass of plants growing to compete for the nutrients (that mass is different for every system) the algae go away. "

"Hi Larry. Doing a buried sump or tank and using the earth to regulate temps is not really viable for a ibc system. Any effect the earth has in changing the temp of your water is mitigated by the rest of the tank that is exposed above the frost line…"

"Larry, I 'm not sure isolating the sump at night would make a difference overall. If the FT stays at 80 and the sump drops to 60 whenever you turn the pump back on in the morning you still have to re-heat the sump water. My sump is halfway…"

You sent me a message a few weeks ago and said you make it to the I-17 and thunderbird area sometimes. Was hoping maybe we could touch base and try and set up a time for you to check out my system give me a tip or three. Please call or text me at 602-909-6858. I'm sorry I lost the message that had your phone number.

Yes I still have blocks.  How many are you looking for? I just went to check to see how many I actually had left.  Turns out I only have 28.

They are 8"x16", and have been stored inside since I bought them a few months ago.

Give me a call or text if you are interested.

David, Thanks again for your offer to come by while in Columbia. I regret that I won't be available. Please congratulate your son and thank him for his sacrifice and commitment to our country. Steve

David give me a shout when you get to Colombia. It's not that far to Goose Creek from there.

Well if you are getting a heavy accumulation of fish poop in your raft beds, then you probably need better filtration before your raft beds or less fish.

I'm not sure if there are any detritivores that would eat huge enough ammounts of fish poop from a raft bed.

However, gammarus might be able to help you some http://en.wikipedia.org/wiki/Gammarus

Thanks, David! I would like to visit with a few friends on Monday, Nov 12th. Will get a head count if this date works for you.

Hey David, I just have two aquariums ornamental fish: Angels, Zebras, Cats and fin tails (algae eaters).  One tank is 10 gal and the other is 30.  I've had organic gardens my entire life until this year.  I recently had to sell my house and move to an apartment.  No outside room to experiment.  Not many jobs for administrative assistance these days.  I'm still diligently looking for temporary so I can stash away $$ for the move.  I too want to get totally involved in setting up aquaponics at schools and helping to educate students about it.  Show Low will be within 30-60 minute drive of where we probably will be so I think it would be cool to work help each other launch.  If everything happens how I want, May will be when we can start building and installing everything.  Keep me posted and I'll do the same.

David,  I will need a lot of assistance.  I will be attending two SCORE workshops, one related to all aspects of putting together a business plan and the other for managing your cash flow.  I will get Will's book today. Glad to hear first hand that it was helpful.  I'm going to try to plan a drive out to Arizona hopefully before winter, say late October and I would love to include a tour of your aquaponics set up and of anyone else's if possible.  I would eventually like to do this on a large scale so I will contact Dr. Brooks. Thanks again.

Hey David, Thanks for the add. Glad to connect with someone local to AZ. You mentioned you have a connection with someone for all size Tilapia. What breed and do you know what their asking price is?

What are your thoughts regarding the different species of Tilapia?

Thanks again

Outdoor aquaponic garden shade structure completion

Posted on March 15, 2013 at 4:30pm 16 Comments

March 15th was the completion of my new outdoor aquaponic garden consisting of a 10' long dual metal rain gutter system that flows into an existing filter box then onto a nft tube then back into the fish tank. I covered it with 40% shade cloth I got at Amazon for a steal.…
