"Sea 90 is awesome.. we only use a minute amount on occasion.. 1/4 tsp / gal in a foliar spray.. then eat some of the salt at dinner. if You add it directly to the tank water, go with 1tsp/10 gallons of water."

Hi Rob. I have been using goldfish and koi in my system that I started one year ago in SA. I would like to add in tilapia this spring. I was told I might be able to purchase some from you. Is this correct?

Have you ever worked with anything vertical or towers? I just got my tower in over a month ago and its way sweet!

Do you prefer gravel over rafts?  Building a setup similar to yours,  just dont want to do it twice.  Never tried rafts yet,  it seems i can grow more in gravel tho.

Hi Rob - it looks like you have a large operation, how many people work with you? Do you keep track of your total output? About how many square feet of growing space do you have?

Cheers

Howdy Rob, It's John Fullerton, I've been away from things as of late. I hope life is treating you well.  Awesome post on the heater.  Just saying hello and checking in, nothing major at this time.  Still working on getting the greenhouse built and finished.  Still want to come down and check you out sometime and just working on figuring out the time that's best.  Life is super busy.  Take care and talk to you soon.
