Pet Forum / Aquaria / Marine Reef / May 2005Specific Gravity Question
What is the ideal S.G. for my 30-gallon tank. I think that it may be a little high (1.028) although the current occupants seem happy. 1 percula clown 1 cleaner shrimp 4 scarlet hermit crabs 1 leather coral riccordea 8 lbs. of live rock other mushrooms I want to add a six line wrasse and more live rock later. Should I try to bring down the S.G. to 1.025 or 1.026? Thanks. Maddie What are you using to measure the SG ? What is the water temp ? In short you are a little high, if you are using a std LFS type of floating hydrometer or a swing arm, at normal aquarium temps, you want to be somewhere around 1.024 -1.027. If it is a refractometer you are OK, which corrected is 1.0265, which is the same as natural seawater Boomer Want to talk chemistry ?

My water temp is 75 F and I am using a std. floating hydrometer. I'm doing a water change now; so I'll bring it down a little Maddie > What are you using to measure the SG ? What is the water temp ?

I keep mine between 80 and 81F. billy Mine certainly seems happier in the summer heat , running up to 84 at times than it did in the winter when the heater kept it at 78. It is worth noting that the increase in temperature simply causes all the inhabitants metabolisms to raise , increasing growth and making the tank look healthier, when it might not actually be healthier. Still, the plate coral expands hugely, as does the devils hand in my tank the warmer the tank gets. D > > Thanks Boomer. My water temp is 75 F and I am using a std. > > floating hydrometer.
