To Sheri and Local Roots....Rhiba Farms (Mark) uses RO in the summer, they fill a 3000 gallon above ground pool with it, let it grow algae, grow some fish in it and use it to offset (top-off) their tanks due to major evaporation that occurs in the summer.  The rest of the time they use Chandler municipal water which goes through a charcoal filtration and a vortex (water restructuring) system prior to use.  They found that Chandler pulls from the canal system for part of the year and they had to make adjustments during that time-frame.

Question: My BF says that the fish at his house are acting like ravenous Piranha every time he feeds them.  So...soft hear-ted for animals that he is, he gives them more food, he wants to know if he can hurt them by over feeding them.  He has the Nile Tilapia.  On the other hand, the mixed breed pink tilapia at my house never seem ravenous.  Odd.

David, I am new at this, but I read that fish with open mouths at the surface need more air.  More bubbles I think.  I am sure more experienced can expound...

I need a little advise, Im seeing my fish at the surface of the water with their mouths up, what are they doing?

My thinking is to make your in-ground fish tank convenient.

Sun and fish water do not mix well, algae. Some fish eat the algae. So all rules do not apply.

If you insulating the top of the fish tank (the sides have earth), save your space in the greenhouse for your plants. then you can plumb-in your needs from the fish tank.

That is my view

I'm about to dig the hole for my aquaponics fish tank.  

I'm trying to determine whereabouts to put the whole system. i.e. Site location.

We've just moved to a new house, and I have a greater choice in site location than I have had in the past, so I'd rather put it somewhere that would be the most beneficial.

My initial thoughts would be near the west wall, so that it would get the morning sun but be shaded in the evening.

I also anticipate putting a small green/shade-house over the whole system at some point, but won't be doing that initially.

All thoughts and suggestions would be appreciated.

Thanks,

John

RO isn't too expensive to operate--salt and electricity. Used ones aren't too expensive, but new ones can be very expensive. It might be a bit much just for an aquaponics system, but if you are doing it for the house, the AP can be included.

I can understand why Rhiba would desire so that much control over their system, since they're commercial and a lot depends on things working just right. For my home AP system, it's not such a big deal if a cucumber doesn't produce quickly.

@Dave: Thanks! :)

Some salt (pure pool salt) is actually good for AP systems.  Check out this great blog post by TCLynx:  http://www.aquaponiclynx.com/salt-for-fish-health 

From what I understand Mark uses RO water and then mineralizes it with the rock/shell bed?  I suppose you get much more control this way.  I wonder how the cost/benefit of it all works out -- aren't RO filters expensive to buy and operate?  Anyone else here using RO in their system?

Good information, Chris, thanks!

I just finish posting some more pictures on my page; click on my name. I have four albums, including one of the brooding female and her young, and another of the male/female tilapia genitalia.
