Hi, I am Don and I have been in reefing for a out 60 years now. I got started when I was 9 with my dad and I am now 70. I currently have a 90 gallon mixed reef with a 30 gallon sump underneath. I currently di a dna microbiome test and found I had high acrobactor sp type 1103 in tank. I was pulling my hair out beforehand trying to figure out why my euphillias were doing poorly. I did the experimental dosing with low dose Cipro. Corals are doing much better now. I need to retest microbiome to see if it got rid of the bacteria.
