where do you guys keep it and why? Just trying to see where the majority keeps their salinity at:)

1.026 good medium considering the corals I have and where they come from.

Using a hydrometer odds are pretty likely that you are really around .020. They generall(not ALWAYS), but generally read high.
Funny you should say that...because I actually have 2 meters. 1 reads at 1.024 (instant Ocean - brand new), the other is at about 1.021 (I think it is Sea-Chem). I figure, I am somewhere in between. I hope the old one is not high because if it is then the new one is really high.

with a hydrometer I was setting to 1.025, purchased a refractometer after I was getting some brown out, it said I was at 1.030, slowly fixed water issue back to 1.025 and the colors are now slowly coming back. For the price of a refactometer, its just not worth NOT having one. Especially the higher quality ones that run 50 bucks, worth every penny.

you are wrong. :D

this was wildly popular in the late 80's early 90's. it seems it still has not gone away. :(

this is incorrect. this all started with using lower salinities to kill parasites that could be living on the fish. the thinking was that if the fish were to be put into a system with a much lower salinity the parasites would not be able to live. the problem with this thinking is the fact that fish should be acclimated, so when you acclimate the fish you are acclimating the parasites also.

fish can handle a huge range in salinity. this is why FW dips are used for removing parasites. the fish can handle it, but the parasites hopefully will not.

it is also cheaper to run a SW tank at a lower salinity, so people running FOWLR tanks would run them lower to save money on salt.

i find it is just better to a salinity that matches as close to NSW as possible.

HTH,

i keep right around .021-.022, i would keep it higher, but i buy my ro/di and mixed salt water from a local fish store, and thats what they mix it at, so id either have to mix my own, or adjust theirs, and im lazy, so i keep it the same as theirs. its just easy.

1.025 but that's with hydrometer, gonna have lfs double check and see what their meter shows and match up the hydrometer. Refractometer on the wish list tho.
