hello reefers. i have a 160- gallon mixed sps/lps tank that has been thriving for the last 3 years. it's doing so well i have some rogue pollicipora spawning and popping up on my rocks. i totally want to redo my rock work with shelves and caves. i have about 100lbs or rock in the tank now that is about 3 yrs old. i was planning on swapping out the old rock with new dry rock. the same amount but a new aquascape with the new dry rock. i dont plan on keeping the old rock as the pollicpora has spread to all the crevices of the rocks. i also can't do it in phases fearing the pollicipora will attach to the new rock so i was thinking about doing it all at once. any thoughts? and after i get this done, i will not have policpora in the tank
