you can cut every one of those out in one pass and be 99% done in five hours work/price of delay. price of playing around vs getting serious, however you want to justify the catchup work
five hours to gain your tank back
after you replace the sandbed via a rip clean, and rasp off the rocks a certain way, you'll have a mere 5-10 as leftovers you didn't see once it's all rebuilt.
those can be taken in a quick pass by lifting up the rocks from the perfectly cleaned rip cleaned tank you'll own, and ablating the new ones right off.
you will go from 500
to 15
to zero
to 2 in like two mos time that you shear off
and then zero. aips are the easiest to beat in reefing, you start with #1. you merely refuse anemone #500 and it can't win, it's technically not stronger than you. all ways you read about are fragmenting
but not surgical shearing of the foothold substrate, that's thorough. and micro surgery
five hours to skip cycle your tank back into perfect clean ready. no cycle startover, keep your rock etc.
