1.025 is salinity? Whats the sg stand for?

[jimsflies]

I personally keep mine in the 1.024 to 1.026 range.

Jamie it stands for specific gravity

[whitetiger61]

i keep mine at 1.025 but have run it up to 1.030 for experiments

[MizTanks]

Ok, so what sg?

[jimsflies]

I honestly don't test very often for specific gravity. When I do I use a refractometer.

sg = specific gravity

swing arms are unreliable and have no way readjust when they get off. I have learned the lesson to use a refractometer, and adjust whenever nessasary

[whitetiger61]

at 1.030 i find corals grow very rapidly but fish cant handle that high sg

[jimsflies]

specific gravity is in relation to pure water. If sg is more than 1, it means the substance your measuring is heavier than water.

[MizTanks]

What's the importance of SG then?

[whitetiger61]

i use a refractor
