what do you try to keep your salinity at in your main tank?

i voted for 1.025 but its between there and 1.026 at all times...

I'm still @ 1.025 - .026

I'm still at 1.0265 (or as close as possible)

NSW = 1.0265

I keep it at 53 on my pinpoint salinity monitor

i try to stay around 1.021 - 1.023

I have a 300gallon FOWLR tank, I am intersted in starting a reef tank. I usually keep my salt level at 1.022. Looking at the results would you suggest I keep my salt level higher to 1.025? just wondering if this level is for reefs or for salt water tanks in general, thanks..

Bobby,
Natural sea water is 1.0265. If you're planning to stock more LPS, then I'd suggest raising your specific gravity (using a refractometer for measurement) up to at least 1.025.

	LPS Large Polyped Stony corals – In the aquarium hobby this is a common division of the species of stony corals based upon the visual assessment of the size of the polyps. Corals in this category were among the first stony corals to be kept successfully in captivity and include many very beautiful species. Commonly kept Genera include Euphyllia (hammer/frogspawn coral), Favia (brain coral), Plerogyra (bubble coral), Lobophyllia (meat/tooth coral), and Caulastrea (candycane coral). LPS corals also include the popular solitary non-colonial stony corals such as Fungia (plate coral), Cynarina (button coral), Trachyphyllia (open brain coral), and Herpolitha (tongue coral). Like their SPS counterparts, LPS corals require good water quality, intense lighting of the appropriate spectrum, adequate water movement and regular supplementation of calcium.

I've been trying to decide on this also.

Does anyone know why 1.026 is optimal (obviously nature decided it to be )?

I recently lost like 9 frags and I was going crazy trying to figure out why. I realized that my salinity had gone to 1.031 but I still didn't understand that small of a raise could affect the tank so much. Then Rich explained he had some problems also because his salinity went down to 1.020.

I'm thinking I will keep it at 1.025 until I get an automatic top-off. When I do my new sump I'm going to try to minimize salt-creep as much as possible also. Right now I have pipes going all thru the sump and they get salt all over them.

Paul, a jump from 1.026 to 1.031 is a considerable jump. It's quite far from a small raise. It's just about the same amount of a variance as Rich's drop to 1.020. I know I'm not telling you anything you don't know already, but stability is key. Those fluctuations are not stable.

As for why 1.0265 as the target......you said it, nature.

Q for you. Are you using a hydrometer or a refractometer? Or maybe a conductivity meter?
