-removal of bga infested wool filter and clean biomedia in existing tank water
-replace wool filter with new gex carbon pad
-rearrange biomedia to biohomeplus ->gex carbon pad -> mr aqua ceramic ring
-added 1ml sechem stability to biofilter after wc.
-aclimate boraras back into tank after 12hrs with 20ml of new tank water injection per 30mins interval
