[tgoeujon]

im going to do my swap over today but im not sure what needs to be done. temp and salinity are equal in both tanks, do i need to acclimate? ive been takin pics all through the build so ill start a thread soon. oh yeah i havent had any issues in awhile so if someone could remind me what causes red slime and how i get rid of it thatd be great
