Got some corals recently. Dip dip dip.
Apparently not all dips are equal - some seem to use proprietary mixture smelling like pine based disinfectants (CoralRX, TLF Revive), some use potassium salts (Reef Primer), some use insecticide & neurotoxins (Bayer Complete).
Reef Primer (potassium salts) is my preferred choice. From past experience, its extremely effective for flatworms for both SPS & LPS. The active ingredient (potassium salts) is reef safe, so its OK to get it into the reef tank. Particularly good for fleshy LPS because some will get inside the body & is quite impossible to rinse everything off.
Downside is that its relatively more expensive.
US forums often mention Bayer Complete insecticide. Its effective but the major downside is that the active ingredient is NOT reef safe. I've used it in the past and noticed that inverts do not do well for many months after that. Even with 4-5 rinses, its probably not possible to rinse off every single bit of insecticide as there will be some remnant amount of inside the flesh in both SPS & LPS.
I noticed that abalone & sea cucumber start shrinking over many months & some died. Suspicion is the pods population is partially affected as well.
Did some reading up on active ingredient :
Beta-cyfluthrin (0.36%): A common pyrethroid insecticide that’s quite toxic to fish and invertebrates, but only toxic to humans in large doses.
Imidacloprid (0.72%): A systemic insecticide that will interfere with the insects’ central nervous system.
Recommendation is not to use Bayer Complete at all.
