Redox,
Can you give a better explanation of how you are cooling the GH. I was looking at a geo loop but as you have mentioned it did not work. What is the best method in your experience?

Hi Ballabooyeah,
You didn't ask me, but I will give you my .02. I cool my GH with the open sides like you mentioned that the other GH uses. The sides roll up with a temp sensor. I have a double layer of plastic on the ends and roof. The growers here in south Florida, say that it helps for hot or cold. I have louvers that open on the ends with a thermostat, that lets heat out passivlly. I use 2 hp heat pumps on all my systems to keep the water temp where I want it. I also use fans on the sumps themselves to save some electric costs during the summer. The fans can only do so much with the humidity like it is here.
I tried the geothermal. It did not work for me. My grd temps during the summer were about 80, so that does nothing. From what I found you either have to have at least 10 degrees difference in ground temps or have so much under ground compared to what you have in tanks, it is not worth it. If I have to have 2-1 or 3-1 in the ground, I don't need it.
I just bit the bullet and pay the electric compnay

Hi Matt,
Thanks for the feedback.
I am looking to write a full business plan and want to take experience from the people in the USA that are running these systems to learn from.
I am heading away from the idea of heating the whole room and just heating / cooling the water.
Also I have follow your threads for a while. What is you view on a first fitout - Go large or start small. If building a PT then I feel the larger the better.
Also are you using any suplimental lighting? Are you using makeup saltwater or natural saltwater - i am planning natural.
Thanks
Andrew

I tried the geo cooling as well , it didnt work all that well for me either. I finnaly gave in to a chiller. A 3ton chiller keeps my water at 79 even in the hottest part of the day. I also have exaust fans that come on when the inside temps go over 79. I think a chiller is really the only way to qarantee cool water. Like Raaden says evap chillers only work when outside humidity is less than 80% and in the summer its never less than that
. I do have some frags but they havent totally encrusted the base quite yet. lots of blues and purples.no lps for sale. the acros are all pretty much stags and I am not really selling them because I finnaly found some acros that are fast growers . I am trying to grow whole colonies then I will sell fresh cut frags of those only. I was thinking about trying some ricordias though
never do a late night water change. I went out to the gh this morning to the terrible sound of pumps sucking air
. I forgot to change out a fiter sock and it caused a backflow of water.right onto the floor. 2" of water in a 220 gallon sump . that is why I always take the time to make 130 gallons of makeup water right after a water change. the sump is still a little low now as I must wait till around noon to put some more water in. nothing like a 260gal water change to brighten everyones day. And Dean nothing is for sale
