ok i did a quick search on here for "galvanized zinc" and found a thread that says they will leach zinc into the system, this tank has set outside for probly over a year, but i will paint it now i see this,
rallysman thank you for the heads up.
i really didnt want to paint it because it will be black and really hard to see if it needs a cleaning, but i will figure that out later,
thanks for the pump suggestions,, i havnt decided on one yet, i was looking at the mag drives because they are cheap/reliable. but they arent efficent with their power consumption and they creat a lot of heat.. Gator i am going to go look into those pumps now, thanks again guys!
