    Hey Folks ....

    The comment "get a book" was probably the best bit of advice offered. The questions cause one to ponder if the person was even awake in High School Basic Science, no insult intended. So many are not. SO, to fill that gap that our wonderful public education system left in this person's basic education, it would be very advisable to not only "buy a book" but to read it as well.

    So Brock, if you have not been run off, it is highly suggested that you purchase a basic book on saltwater aquariums. Also, please start in the newbies section. You won't get beat up so badly. The other areas of this playground get rough from time to time. Also, read the 3 fundamentals sections. A good read in its own right.

    Now to be honest, SG, PH, hardness, Ca, all of these are interrelated in one way or another. One effects the other. So it is not a simple answer. And depending on your water source, could be a breeze or a never ending battle to maintain acceptable water quality.

    The water's fine. Jump in.

    Cheers,
    Ray

    pH, pH scale -- ((chemistry) p(otential of) H(ydrogen); the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is acidic and less than 7 is basic)). I personally try to keep the pH in my reef tank around 8.3.

    To prevent one from nuking their tank...to raise SG (specific gravity) in your system, you would add saltwater to replace what has evaporated from the system. To lower it, you should add fresh (reverse osmosis/de-ionized) water in amounts greater than what has evaporated.

    If you are working with water in a separate container not attached to the system, you can add salt to raise the SG. It isn't advised to add salt directly to the system as it can "burn" the livestock.

    Hope this helps, welcome to 3reef and beware of the wildlife. ;D

    Don't you mean that PH above 7 is basic and below 7 is acidic?

    Not trying to pull your chain, but we do want to put the correct information out there.
