I have never seen peppermints turn on coral, I have see some ignore the Aiptasia, but considering the alternatives, it is best to throw some into the tank, and if you have a problem, throw in food wait until they come out, then net them.
Petco delivers. I have a biocube mixed reef with about 23 gallons of water. I use one box a change. Only works for small tanks. I order 4 boxes at a time and the shipping was $5.99 last time. It is expensive, but it saves a great deal of grief for a small tank...
It was a general comment. In general, most things do not get repaired. Throw away and buy another. Cobblers? TV repair? Fuel for lighters, vaccum cleaner repair you just don't see them anymore and if you do they make me look like a kid.
It really depends on your definition of "bleaching" If you mean white coral because the live tissue died, or because the symbiotic algae was expelled and the reason the symbiotic algae was expelled.
The new jeeps are designed to get yuppies to work when there is 2 inches of snow on the road without actually getting out and turning the hubs. It is handy, but where will you get the electronic parts in 10 years.
I think we have all bought two corals and where told they were different, but when put next to each other in our tanks turned out to be the same coral, just different colors under different lighting after a month or so.
