water changes

gramma royale · 07-22-2001, 08:36 PM

Hi all,

Got another question for you experts. When I'm doing water changes, I've just been adding premixed saltwater from my LFS and a little RO water to lower the SG (my LFS SG is 1.027). Is this OK to do? I haven't really thought about it until today. I've checked the SG and it's about 1.022.

I don't trust any kind of water I buy from my LFS. If you can I feel it would be better to make your own water.

Welcome to Reefland!

Unless you really trust the LFS source, then mix your own. If your comfortable with the LFS source, calibrate your hydrometer/refractometer with theirs so when you dilute it your on the same level.

Adding your own fresh water to the pre-mixed isn't a problem as long as you closely watch the SG.

thanks for the info guys. I'll talk to some customers about the water at my LFS. As for mixing my own, I've had bad experiences with it

. Basically, I attempted to keep a 10 gallon nano reef a while back. For this particular tank, I tried mixing my own seawater. I even got one of those cool fans to mix the water. three hours later, I finally got the SG up to 1.010 at 79 degrees. I've no idea why it took that long. I talked to some other people about it and they think I suck cause it took me that long to mix the water! For some reason, everyone manages to mix the water in 30 minutes or less. I'd like to know how!

first of all its best to let youre new seawater to sit for at least 24 hours ,to allow the ph to stabilize.you should (or at least i)use a powerhead and a heater in you mixing container(i use a rubbermaid trash can).mix youre own ,my lfs sells what they call 99% ro water

I guess we are lucky here in San Diego as we can go to Scripps pier and get NSW for free. I store it for about a week before using. My salinity says about 1.025. Never had any problems using NSW

Ahhhhh, San Diego. I actually just moved from there to the Bay Area. Lemme tell you something about the price difference. In San Diego, I could get a 10 gallon glass tank with hood and glass top for less than $8 at Clairemont Tropical. Here, a 10 gallon glass tank BY ITSELF is $15.
