water change

[beachlife]

I have a 150 gallon reef and I need to do a water change. The water I want to use is natural sea water that gets delivered to the LFS. I have had the water for five days in close containers. Is it ok to use?

Yes, but you might want to drop a power head in it for a little while just to aerate it.

Check ammonia in it too. Various processes involving bacteria, soluble organics, and possibly dead suspended organisms can cause ammonia problems. Also, if it smells of hydrogen sulfide, do not use it.
