Hows everybody doing? I have a freshwater tank with a pleco and blue lobster. Bought a Ruby Scat and blackfin shark and puffer. I have to add marine salt for the brackish fish and was wondering if this would harm my lobster and pleco.
From what I have read the Blue Lobster has been reported that freshwater salt greatly increases the health of the species. I won't post a link in case it is a competitor but you should be able to google search it.
As for Plecos, most of what I have read said it's ok for medicinal treatment, but not long term.
I don't know for sure, but I hope this helps some.
