Salinity

[brayden]

I have downgraded my 135 gallon to a FOWLR. Some of my fish are a sailfin, royal gramma, porc puffer, wrasses, gobies, etc. What would you recommend for a salinity level?

specific gravity around 1.022-1.025.

The salinity of the ocean is ~1.025, I try to mimic that in my tanks.

I used to run my FO tank at 1.020, but have since risen it to 1.025. Honestly, I don't really notice any difference. The fish still behave like they've always behaved, my skimmer still pulls out the same amount of black nog and my sulfur denitrator is still guzzling nitrates.
