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.....

Did you wash your sand before adding in?
Any mechanical filtration in your tank?

My pump for mixing saltwater always looks like this and builds up this stuff after making saltwater for a few weeks. So if you had the skimmer running during this time this could be the cause. |

Thanks. Thanks. Let's keep equipment cost as secret. Hahaha... Quote:
Remember what I post on my first water change ?http://www.reefcentral.com/forums/sh...&postcount=100 I think it may contributed a lot what happen here. Plus, even I did not use tank to mix initial saltwater, I did run small amount salinity correction by mixing salt in minutes and then pull in sump, which I never do it this way in old tank. What am I thinking A lesson learn and thanks, my friend... I use zeovit reefer's best coral reef salt, BTW....

I think I can accept the main reason cause calcium build up within 20 days due to my careless (e.g. pull in not well-mixed saltwater, dosing solutions near to pump, etc...). However, it must be other chemistry reason out there that I have not yet figured out cause rotor build up different things.
Please see below... first picture shows that rotor build up dirt RD 6500 @ 2013.5.1 second picture taken yesterday but similar to last time de-mount pump in old tank, it build up calcium....why!!!??? RD 6500 @ 2015.2.23

However, if its getting the buildup again, then I'd say it is a different issue. Check if the pump is getting too hot it can cause localised calcium and mineral deposit. If you can, place the impeller in vinegar from the grocery shop and then allow the calcium deposit to come off fully. Might take a few hours, but its OK. When newly cleaned take photo. Then start up skimmer again with clean impeller and see what the result is after a few days. If it getting the strong calcium deposit within a few days, I think heat or excessive dosing or dosing near the skimmer intake is maybe causing this. |

One more thing; if there is still some fine silt from the newly added rocks and sand, this can also cause the deposit on the impeller. Just clean in vinegar and recheck.

Great setup you have going there. Why don't you use equipment made in Taiwan. JNS made in Taiwan is of very high quality and can match the equipment in terms of performance, much cheaper to.

http://edafologia.ugr.es/carbonat/paramew.htm The RD3 Speedy has a red tube to cool down rotor, but it also indicate RD3 rotor maybe over heat, plus the red tube may also increase chance to pull my un-mixed salt into rotor. Quote:

H2Ocean Pro is an evaporated salt, I think I am going to go with an 100% artificial salt like ReefCrystals. I might even switch to KZ Reefers best. |

Amazing build quality and attention to detail.
Residue on impeller could also be related to dosing intervals. Simple one but easy to overlook. Are you spreading your dosing solutions intervals or all at the same time? This combined with heat could be speeding up sediment build up on impeller. |

My KH dosing is 24 times a day at clock hours, and Ca, Mg were dosing at 3:10, 15:10, and 9:10, 21:10 separately, and now I change them to 3:30, 15:30, 9:30, and 21:30 to extend the gap between KH and their dosing times. Hope it work better. Many thanks.

Thanks.
BTW...I do not have experience to keep Pseudanthias parvirostris ( x8 ) and Pseudanthias pulcherrimus (x2 ) mixed in tank. Any tips and suggestions are welcome

Thanks.
Allow me sharing a few SPS in tank for more than 40 days. They start to develope different color, PE, and growing. I hope turn to good direction, but not sure yet.
