Questions about SG

[ercfish]

A quick question about SG. I noticed that alot of the books I am reading recommend a SG in the range of 1.020 to 1.023, but have seen several times that people on this board will recommend a SG of around 1.025. Was wondering why this is? TIA

I think the reason alot of ppl run it high is there is less chance for diseases and parasites. Same with running the temp at 82-82f That is from what i have discovered.. Please correct me if I am incorrect anyone.. Most run SG at 1.023 @ 80 - 82F

Im not sure if the absence of diseases and stuff is a primary reason because there is less chance of certain diseases and stuff at lower SG as well. So i think the argument could be made both ways. I think it might be personal preference since the book gives that range. As Cj said....most in here keep between .023 and .025. I too could be very wrong here too, but im sure you will get an exact answer from someone shortly

I keep my tank at 1.025 at 80-82 F, because that is the average temp and SG of a natural reef. The lessened stress of being at natural reef temps and salinities is much more beneficial (IMO) than the slight advantage a lower SG has towards parasitic infestation. Lowered SG, to my knowledge, has no effect on disease, only parasites, and heightend SG has no effect on either.
