Hi,

I'm in the NJ/NYC area and today noticed my tap water tasting a little moldy. I read that Algae can bloom on the surface of lakes, reservoirs, and other water sources. It suppose to go away with colder temps coming in.

My question to you is would doing water changes around this time effect my tank negatively? With the presence of algae in the tap water?

Thanks!

If your city treats the water with chlorine, chloramine, ultra violet or other sterilizer the algae is likely dead, and filtered out. The remaining taste (or smell) is not enough to make algae grow in your tank.

However, if the water had changed in other ways (mineral content, other) then that might alter how your plants are growing, and this might invite algae to grow. Not because it came in with the water, but because it was there all along, but the plants were out growing it.

The taste may be from algae or other changes in the water supply but it is still safe for drinking or tank use. Algae comes in so many types and forms that it can be found lots of places, even underground. The rotten egg smell used to be thought of as coming from iron deposits underground and people just had to live with drinking bad water. We now find that the iron is not the cause other than there is bacteria who live on the iron and the bacteria cause the smell. We now can just do a bleach soak of the well casing and nearby and the well is good again. Wish I had known that when I was growing up! Lake turnover can change the flavor of water, especially if the lake is getting a pretty heavy dose of phosphates. You don't want to go water ski in a lake that has turned over. Too many gobs of gooey grung floating around. A larger problem in cold areas.

I just read an article about the world's larger water treatment plant to use ocean water in San Diego. Expensive water and pretty late to get started on building but at least they do have it started.
