My DC pump (RD3 Speedy 80w) was STOP last night.
It only run for about 20 days. Thanks God today is last day of Lunar New Year Holiday so I can work on it.
Please see picture below...First picture was taken on my Royal Exclusive RD3 Speedy 80W return pump (DC). It was completely stuck, I spend almost 30 minutes to pull the rotor out and clean it. The 2nd picture was taken on my Royal Exclusive Red Dragan 6500 return pump (AC), I think it will get stuck soon.
Now leave the question is.. Why only less than 30 days calcium(?) buildup dramatically!? I was using same balling method as my old tank run for 3 years. In last 6 months of old tank years, I did aware my Calcium(?) build up faster since I swap my baking soda, CaCL2, MgCL2 to different sources. Could that be the reason? I now using Arm & Hammer Pure Baking Soda from Costco, which many reefers recommended and use it as well. What could be the reason my Calcium(?) build up much faster? I have to solve the puzzle to avoid it happen again when I am out of town....
Any idea? Please chip in.....
