The DC-201 direct current compressor would probably be best. This DC oilless air-compressor will give you around 1.3 CFM of airflow which is more than enough for two diffusers in the tank although one would likely suffice. The DC-201 can be run solar direct by using a linear current booster and a few panels or if you know anyone who can help set-up a battery powered system that would be a good option. I wouldn't be able to help with the solar requirements as far as panels go as that's not my field but the AMP requirements are all listed on the webpage http://www.thepondreport.com/solar-battery-pond-air-pumps.shtml so whoever was setting up the DC system could use those numbers to get you up and running.
Regarding the algae information. We use a few natural products that are safe for animals and people so they could probably be helpful. Do you have algae growing in the tank already? We use the algaecides and natural bacteria listed here: http://www.thepondreport.com/pond-algaecide-natural-bacteria.shtml There are different formats to suit your tank size.
Aeration is key to assisting to keeping the algae down and will enhance the results of the bacteria. Regarding the aeration: The PR-DC201 DC compressor is supplied with a 3/8” hose outlet so I will include 50’ of 3/8’ weighted airline. Because you are using the DC compressor in 11 feet of depth you need to use 9” ceramic-type air diffusers. They're machined from a solid block of glass-bonded silica. They produce a uniform medium/fine bubble and are very resistant to clogging. And when cleaning does become necessary because of a buildup of calcium precipitate or bacteria, an light acid bath restores them to like-new performance. Two-year guarantee. Made in USA. The diffusers are 9" L x 1.5" W, 3/8" OD barb.
I will also include a pack of 10 diffuser bumpers to keep them from banging the tank. I’ll send some stainless steel clamps for the hoses and diffusers. I will also include the two way adaptor control valve; this manifold will connect to your compressor outlet hose and will allow you to split the line in to two lines and control the airflow in to each of your diffusers. The connection of the DC compressor (pigtail wiring included) to your panels, controllers, regulators and boosters and solar panels is something I can't help with and would be best to have done by someone knowledgeable to ensure the compressor isn't over/under worked.
Your order would be:
1 – DC Air Compressor (PR-DC201) – 12V 6 to 8 AMPS 1.3 CFM at 6 PSI (6 month warranty)
1 – Roll of 50’ weighted airline 3/8” ID 2 – Ceramic Diffusers 9" L x 1.5" W, 3/8" OD barb
1 Pack – Diffuser Bumpers (rubber) use 3 per diffuser
1 – Two –way valve control manifold with 3/8” ID fittings. Uses fine adjustable globe valves. PVC construction.
1 Pack – Stainless steel clamps and required connectors
Total cost with shipping to your drop-off location in Texas so you can bring it to Mexico with your team is around $750 US complete. More details on solar aeration are here on our Solar Aeration Webpage
