From my understanding both POTO and TSA regularly Interceptor their tanks and have at least some sort of coral quarantine. If you are going SPS dominant you should go the KCl route. If you are only dipping your corals once (especially in something like just CoralRx and Lugol’s) you should look into running an Interceptor cycle if you really want to chase the crazy polyp extension and 4th and 5th colors on SPS! Your tank can look plenty nice without these steps but when I go to coral shows I can tell which vendors are paranoid about SPS pests and which are not. Same phenomenon with sellers on Reef2Reef: it is usually very obvious from pictures which sellers take SPS pests management seriously.I do monthly ICP and dose trace elements consistently, have an apex setup etc, most parameters are pretty stable for what they are at. I did see like
What you said more light with higher nutrients I’d assume to prevent bleaching with an increase in N/P consumption. Got most of my frags from TSA and a few from POTO, only dip I did was a 5-10 minute mixture of CoralRX with some Lugol’s
If you want ideas on how to better control for pests what I do is dip any incoming SPS for six weeks straight (once a week) in KCl. The only exception is if I am going to do an Interceptor cycle in which case I depend on the Interceptor to handle the incoming pests.
Online I only buy from sellers who regularly Interceptor, with the only exception being if I purchase their coral ahead of my own cycle. At coral shows I ask vendors whether they use Interceptor and only purchase from them if I like their answer and their coral has very good polyp extension.
