Will Nutrients Eat an Aluminum Resivior?

Hey, guys...
I'm designing and building an Aero cabinet and need to fabricate a couple rez tanks.
I would like to use aluminum because I can weld cooling fins along the side and pull outside air across those fins to dissipate the solution temp. My only dilemma is weather or not aluminum would corrode and contaminate my women. Next option would be mild steel w/liner inside.(slow heat transfer to the fins and will cool slower) and then Stainless steel.(Expensive and slower dissipation.)

I'm sorta stuck here, amigos. My guts tell me minerals will eat the aluminum and contaminate my gals.

Hey! Even if ya can't help, check-out my stuff when ya' can:mrgreen:

I would not use any bear metal except titanium and even then only some titanium alloys are really nearly completely safe. Salts just like destroying metals. Glass is a better heat conductor than plastic if that helps. Fins in contact with an all glass aquarium work well. Ie aluminum tubes strapped against the aquarium sides for natural convetion heat loss.

Eventually I think we wil see the day when some manafacturer offers cooling tubes for home and hobby use. They would just be a titanium tube closed at both ends with fins at the tiop end. Refrigerant would be used passively to transfer heat from the bottom of the tube to the top of the tubes where the fins would dissipate the heat. They are are used all over the arctic regions where the ground is frozen all year around (permafrost). When you build on top of frozen ground you want the ground to remain frozen. If not the ground sinks when the water in the soils melt and you foundations tend to break quite quickly over big sink holes. Most people have seen pictures of the Alaska oil pipe line and have seen the finned tubes. They are just keeping the ground frozen around the pipe line supports (vertical support members). http://www.absoluteastronomy.com/topics/Trans-Alaska_Pipeline_System

Thanks Fatman7574! Great info! I've used aluminum blocks clamped to thin gauge mild steel to pull heat away from the cut/weld area to help keep warpage under control. Great idea!

I'm gonna' think on that...

Thanks again, Fatman!
