Good Day,

How is everything with you, I picked interest on you after going through your short profile and deemed it necessary to write you immediately.I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on this email( ) for the full details,
Have a nice day

Thanks God bless.
Mrs Abiola.

Howdy Rik,

This is just a note of appreciation.  

Thanks for starting a Arduino & aquapnics group.  I'm a newbie in both, and will most likely be of little help to you, but I suspect you may be of great help to me, so I just want to say Thanks!

Currently I am building a greenhouse to shelter a aquaponic system, and I hope to automate it with the ardiuno I bought last year.  I also have a C.H.I.P. which may also come in handy.

Hey there Rik, glad to see you joined the Sacramento Aquaponics group.  Had heard about you previously from Susie G.  Curious though, you being a little distant from Sac:  any particular reason you joined the Sac group?  -- Paul Trudeau

Hi Rick,

There are several operations on Maui: Kai Manu, Waikinalani, Maui Aquaponics (which we haven't heard from yet), and more.  I seem to be the newest of the bunch.  Still having trouble trying to get my nitrogen cycle to kick in.  Please feel free to post a comment on our group when you visit Maui next, and I'm sure you'll get a lot of invitations, including mine.  Kai Manu seems to be the most established on Maui, where Nick Oosterveen is using aquaponics as part of a much larger sustainable living program.  See

Hi Rik,

Thanks for joining the Aquaponic Gardening community - we love to see experienced members! I hope you find it a fun place to explore aquaponics. There is a real blend of experienced and new aquapons in this community, so please don’t hesitate to get in there and start asking, and answering, questions. I'd also love to see some photos/ videos of your system if you are willing to post them.

We have just a few simple rules: stay on the subject of aquaponics and keep it cordial (no flaming!). If someone decides to break these rules they will get a warning, and then be banned from the community after that. But of course I’m hoping that never happens!

Thanks again for joining us, and I look forward to getting to know you.
