specific gravity ???????

[danfish]

in a poll taken that i saw in another forum most of the tanks had it at 1.025 and my tank is at 1.022 and that was only like 6% of people that voted, while 1.024 to 1.025 made up 62% of the poll. i though the gravity should be between 1.020 to 1.023 (thats what my deep six says ) am i too low? thx in advance.

most fish surive between 1.020-1.025 A lot of ppl like to keep it a little higher to be on the safe side i guess

Fish only I would go with 1.020 to 1.022.
Reef tank I would stay in the range of 1.024 to 1.026

Here's our poll.

natural sea water SG varies around the world.
I think the average taken from reefs is 1.025.
that's why most people go with that number.

I don't pay too much attention to sg except when I'm mixing for a wc I try to hit it around 1.026.

What's more important than the sg is stability. Keep the sg stable & you will have success.

Bris,
You're dead wrong. Salinity is VERY important when it comes to inverts. the animals we keep have a 'target' salinity. Ever try keeping a shrimp in 1.021? It's fine for fish but the shrimp dies.

Dan, deep six that hydrometer. Chances are it's very inacurate anyhow. Get yourself a refractometer and calibrate it. Then you'll know exactly what your reading is.

When doing a water change, I shoot for EXACTLY what my tank is at. which is exactly 1.024

BC, my post was to imply as long as one were within acceptable parameters for what they're keeping. To illustrate, keeping a stable sg of 1.000 or 1.060 would not intail success.

I know a lot of very established wholesalers (even here on the island) and they keep most of their fish in 1.010 and maintain copper in the FO systems. Obviously the copper and SG sensitive fish are kept in a seperate system. Fish are able adapt and do well in much lower salinity than the inverts we keep as reefers.

1.024-1.026 is the range for Reef Aquariums...

Everything else is crap. Refractometer is the best piece of equipment that is still cheap. Save a coral life and get one.

Jeez a simple question turned into a debate.
