Been a week plus already trying to finish up regular tank maintainance. Lots of thing happened... as for yesterday during skimmer cleaning, i broke the Rio pump impeller. Not really a big thing which i can glue it back. I broken the front part while trying to pull it out. I did tried out what and how good the pump running without that part but its only produced good flow at limited time only... after that it went kaput. Enough of trying... i just glue it back, hope its good as new. Anyway this skimmer's pump cleaning resulting a bit annoying vibrating sound... the old like a new pump sound is back! After trying several times, its just not going anywhere... the sound still there! Since dun really want to waste time and most importantly more money on this, just trying to get the slowest vibration sound possible and let it be. I dun really know what happened and why the sound is back (before this not as loud as this), its the first time for this kind of loud happened after a long time.

About the Ca level, everything is back to normal. I'm not trying to get 400+... as long as its same reading as newly saltwater mix its ok for me. Been doing WC bout 4 times i think with about 10-20% each time plus adding some Ca buffer, now its increase from 200 to 360.. so its cool.

Other than that, i also removing the filter sock which is causes banjir last time. Its also needed lots of cleaning since i only have several of that. So for now i'll skip this first.

Next will be away from tank for awhile and jom balik kampung!.. Till then happy CNY and Selamat bercuti.
