Shout out to 
@H2OPlayar .  Visited him yesterday. Wow, he have a great tank. mature colony in a beautiful setup. I hope one day, my coral will look half as nice as his!  He passed me quite a few frags. Dip and went straight to DT.  My coral QT is not up to standard and hate bleaching healthy coral like i did previously.  A few pods comes out during the dip, nothing really anything i should worry about. 
On a separate topic, had a "Ops moment" today
Did a weekly water change.  
1. Fill the container with RODI   - check
2. Add salt   - check
3. Turn on pump  - check
** water in the DT start turning cloudy **
WTF.  I accidently have the valve set to pump water from the mixing container to DT.  Ops..  I'm glad only small amount of un-mix salt get to the DT. Not measurable salinity change.  I know this is not good for the fish and coral, but hey its accident and shit happens. 
Alk:  7.7    (hanna)  used to be in the 8.4 range..
Ca -   420 (salifert)
Mg - 1360  (salifert)
Nitrates = 5-10 (redsea)
I just change the salt to Fritz. Need to measure the new saltwater parameters before adding to tank.
I should look into dosing. But first off, is it normal for Alk to drop but Ca and Mg hold steady?  I have been reading up on Carbocalcium & bio-Magnesium by Tropic Marine. The ingredient of the popular All For Reef, minus the trace elements.  Either that or Kalk.
More research later.
