Personally stay in admiralty and met quite alot of reefer from admiralty, woodland and yishun side. So i think north side also have lots of reefer only that they are more low profile.
i was not aware sea chem has trace elements
thanks for the input
so how's the results with sea chem?...colour booster?
i heard the aquaz trace element is similar to zeobak....brings colours to an amazing intense level...but i've yet to try it
