 Re: Qt tank?
I believe hypo refers to hyposalinity. Hyposalinity is the state where the tank water salt content is way below that of ocean water. Usually 1.010 to 1.008 sg are used. I use 1.008 as it allows for some evaporation to occur and still keep me within the effective range. As parasites are unable to regulate the amount of water in their body and rely on osmosis, the lower sg (specific gravity) will cause water to rush into their little bodies, bursting the little buggers. It is the safest way to deal with ich though it takes 4 to 5 weeks to work as ich is only vulnerable to this type of treatment while they are free swimming trophonts (babies). You can google Osmotic Shock Therapy to learn more.
