So my daughter had a surgery in Florida. She will be down there 4 months for a procedure, and I hve been gone 3 weeks. My wife is still there and we will trade out half way through. Anyway I took my 5 corals to the LFS who is pretty kind to me, traded in for store credit, and entrusted the care to my father for the 3 weeks that we would both be gone. He followed my instructions exactly and did a great job, including a big water change halfway through. But he didnt bother to run the magnetic glass cleaner as I do daily... so if anyone was wondering what 3 weeks of no glass cleaning looks like... here it is! On a related note... my shrimp literally has algae and barnacles growing on it... or what I always assumed were barnacles: the little white nubs that grow on unattended areas in the sump usually. Should I be worried? He obviously hasn't molted in 3 weeks...
