hello sir..
how long you quarantine your coral? is it to get rid of ich, velvet or pest ?
and maybe if you can share your method and equipment for coral QT?
That question is totally loaded...
Depends on the coral, coral base, origination, purchase place. and MOST of all willingness in regards risk.
The purpose is for fish diseases yes, as well as coral pests.
I have only SPS in my tank.. So in general I do the following:
1) Inspection before purchase
2) Acclimate to Coral QT tank ( basically same water from DT, but not directly plumbed together)
2) Dip the coral in CoralRX
3) Remove all plus, discs, bases, dead areas, etc no matter what. Essentially creating a fresh cut with only living tissue.
4) Set in QT Tank for a few hours. Observe for pests or anything I missed.
5) Some fresh cut go into the DT the next day or not for 76 days depends on what I see and where it came from. This is under my willingness of risk for each coral. I am having a brain fart currently and do not remember if fish diseases can a encyst on living acropora tissue.
The process would be very different for LPS and softies: Dip, inspect, dip, inspect, wait 76 days minimal to no expectations.
My coral QT setup:
Heater
Radion XR15 Gen 4 pro
return pump
powerhead
filter sponge
carbon
one piece of live rock
Auto water change system from DT
