Bang Guy, say what you will. Do yourself a favor, it's time to review physics and chemistry. And before you make any snarl comments use your brain, for once.

I am not referring to the accuracy (or lack thereof) of the hydrometer mentioned. Look at the scale, on the right is the SG and on the left is the salinity...linear relationship. Of course, reading will be altered when a piece of bubble is attached to the pointer. You don't have to be a rocket...

The response was meant to assume a linear relationship between salinity and specific geavity. For a given temperature, salinity is directly proportional to the specific gravity. Ie., as SG increases, so does the salinity. I disagree with your claim that salinity does not change with increase...

OMG, that is awesome! I kinda like that crab's hairdo:D But seriously, you think the yellow polyps will adjust to constant movement of the "rock?" I know that they retract when they detect movement. Hmmm...you have aiptasia in your tank?:D

Absolutely, you can use that water. Even if it evaporated, the only change that may happen is decreased volume, nothing else. What seems to be bothering you?

Turning off any filtration during phyto feeding certainly helps increase probability of food getting captured instead of getting filtered. Powerheads, however, need not be turned off because current produced by them helps in the process of food dispersal.

Salinity has to either stay unchanged or increase on a newly mixed salt water. As mentioned, typically, salt does not dissolve completely when newly mixed. Factors such as temperature contributes to this lowered solubility of solids. When you use a cold (were talking much lower than room temp)...

I got an Aqua-C EV 180 for my 90 g, it sits in the sump. I'm content with it and not considering anything else...for now:D

May I suggest, easy on steroids (in reference to your pic).:D

Same wavelength, broomer. I'm afraid.:)

Broomer, I agree that equilibrium has to be achieved that's why we need to let water sit before adding to the tank (although the article did not touch on dissolving solids in the salt). That's the point of the article. That there is a danger of high O2 content in it that we don't see as BUBBLES...

You don't need to see bubbles to believe. The article talks about DISSOLVED oxygen. Besides not all bubbles in your tank is oxygen even if you use an air pump. Atmospheric oxygen is only 21%, most of it is nitrogen. You don't seem to understand the point.

Hi, I bought a bucket of Coralife salt yesterday and got a free T-shirt inside. I happened on a Newsletter inside the bucket. In it is an article by Bob Fenner concerning the danger of using freshly mixed saltwater with high concentration of dissolved oxygen. He said that high O2 content of the...

Looks delicious! I mean, gorgeous...yes, that's what I meant.:) Those claws look sinister, I hope it does not bother the fishies/shrooms. Thanks for sharing.

I know of only one...chocolate starfish. It paralyzed my derasa. Thank goodness I saw it before it was too late. It took the clam about 2 hours to exhibit some movement of its mantle. It recovered eventually. Needless to say, the choc starfish is now dried and sits on top of the canopy.:mad:
