Refractometer, but I started the new job and just getting use to a new schedule made looking after the tank difficult. In addition I added salt water as a top off not thinking.

Thanks! That was quick, I'll read thru it later.

Good article Deano (once again).

A VERY brief excerp:

TEXT BY RONALD SHIMEK Ph.D. :

To keep the salinity at around the optimal reef values, at a temperature of 77 degrees Fahrenheit (25 degrees Celsius), the specific gravity should be no lower than 1.025 (35 ppt), and can range up to 1.027 (37.5 ppt). The middle value of 1.026 is a much better level from the point of view of the organisms. Keeping the temperature at a more reasonable 84 degrees Fahrenheit (29 degrees Celsius) would result in a lower specific gravity range because the water becomes less dense as it heats up — the range being from about 1.024 to about 1.025.

Thats by Dr. Ron

, I take that back.

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? Russ

is is true the saying "1.026 is 10 times saltier than 1.025" (and so on). i read that somewhere a couple places but forgot where.

I think you're referring to the pH scale.

Reef Stability?

masterswimmer · 03-11-2006, 02:12 PM

Dean, I see a flaw in Shimek's theory. He tries to quantify the instability of the reef. He does that with very good evidence. I don't disagree with that. However, the stability comes on a daily basis, macro managed so to speak. If it were micro managed and the stability remained constant all day everyday then it would be the way we try to maintain our tanks.

The problem with his instability theory is that IF our tanks do vasilate in temp and SG consistently everyday the way the lagoons or atolls do, there would be no issues IMO as well as Shimek's opinion. However, the lagoons and atolls consistently change the same way. Look at the graphs. Our tanks are not consistent with their changes. It's very haphazard in the swings.

Damn, thats hella insightful.
