First I'll start with... I should have know better then to get a fish from petco and not QT it... anyhow I recently started up a 75 gal FOWLR Mostly DIY rock Live Rock (taken from my reef tank) Live sand Wet dry W/LR rubble 5 engineer gobys (no signs of ick) 1 humo trigger (has it lightly) 1 porky pine puffer (ick just showed up but looks bad) 1 kole tang (He's the one that infected the tank, has it lightly tho) 1 damsel (has it lightly) I removed all the inverts (star fishes, crabs...) I want to run hypo salinity but I have read, not to expose live rock or live sand to hypo is that only because it will kill off almost everything on/in the LR/LS? If that is the case and I decide to run hypo to combat ick, after the 6 weeks couldn't I simply seed the LR/LS by taking samples from my reef tank? Also, what precautions should I take while running hypo if the good bacteria in the LR/LS should die off (or can it?).... Carbon... weekly water changes... ? Thanks an advance for any info!
