What exactly are the calcium requirements of an octopus (bimac) tank? Is supplementation required and what levels need to be maintained for optimum health? TIA!

Hi Paul

octos require regular partial water changes and that will put in enough calcium. No extra calcium needs to be added.

Thanks Colin. Is it a parameter that you even need to test for in a ceph tank? Also, would a monthly 10% change on a 100 gallon be sufficient? Thanks again.
