Thanks Kim.

I now have 2 in foam around the FT and put up some more sun shade to  block even the early AM sun. I have been dropping ice faster than my freezer can make it. 

I had a fan running for 2 days and lots of ice and got it down to 84*F. I decided to take a risk and dropped in 7.6 LBS of dry ice into the sump of just over 250 gal.  It boiled for over 10 minutes and dropped the temp 4*F. It also crashed the PH 2.3. Our PH has been very high so when I did my test the next AM I found my PH at 7.0 and no dead gold fish. Think I got lucky. Anyway I added more ice and sun shade today so I will see what it looks like in AM.

DJ, many people insulate their tanks with white board insulation.  I have some cushions from an old couch on the outside of the tank covered with some shade cloth (mostly for looks).  I have my system under an arbor.  Live shade is supposed to be more effective than a typical structure.  on super hot days u could put a gallon of frozen water in the tank

Today in Southern UT it got up to 109*F and my new insulated tank hit 90*F. I know most of you on this site deal with much higher heat. What do you recommend to keep the temp down? I have an IBC system with 4 GBs one full IBC sump tank and a full IBC fish tank. I only have about 40 gold fish 2 inch or smaller right now.

@Arlene Boyle, I would be happy to give you some red wrigglers, I am over at 20th St and Bethany Home.  I will trade you them if you will show me your AP system.  I am starting to gather materials for mine but it will be at least a few months before I am ready to start.

Time for me to stop talking and start doing. Came home last night to no power lol. I'd only been gone for a couple of hours but the survival mode kicked in. Went to the garage, got the generator (which hadn't been started in years) put in gas and pulled once.... my prayers were answered. Strung out extension cords in all directions got everything going and the power came back on. No more putting off an auto backup of some type.

It will take about 10 years to break even with solar but there's the pride feature of DYI and the (why does he have power) during  transformer outages. Like that never happens in Phoenix. lol  

Batteries are a can of worms. Gel cells are expensive and have a low reserve amp ratings but there do last the longest maybe 15-20 years.  There can be dropped to below 11.5 volts and survive.  Car batteries can not be dropped below 11.5 volts or you loss cells. Car batteries are the cheapest money wise but not the best long term maybe 5 yrs.. Deep cycle are slightly better than car batteries but they last about 5 years. I like tractor ( farm) batteries 6v  which have the largest reserve They last a little longer before replacement but you have to wire them in series to get 12 volt. They will give a longer up time before they get to the critical  11.5 volt stage and they cost about the same as car batteries with a high reserve.

Caution batteries can cause quite an arc. lol be careful.  Never store in the sun or inside a house (lead). They will last longer in a cool  shaded bin.

While solar is a good an off grid solution you won't beat cost per watt from the grid. If you're looking for a power backup then a couple of batteries and an inverter would be a good economical solution. You cold even throw in a small solar charger. For longer term outages I would rely on a generator. Again I'm no expert.

Cool. Thanks for the feed back on the Solar. I haven't started my research fully yet. And I do agree, that harbor freight solar set up they have is crap. :) I wonder what the life of a deep cycle battery would be with this heat. I know car batteries do not last as long as they do elsewhere. I have a couple of cooked ones that I can get recycled/refurbished. 

The cost per watt: Thanks for the insight there!

Aquaculture America 2015, the US meeting of the World Aquaculture Society. Aquaponics is the fastest growing session and second largest last year in Seattle. Hope to see you there!!

I watched a youtube vid, where they used 2 12v pumps to get the height and volume they needed.  Basically by using 2 small pumps in series they got the volume and height using less wattage than one larger 12v pump.  This was an off grid system.
