Cyano deaths?

[asylumdown]

I'm using tap water for my tank because I don't have any other options right now. With weekly water changes, I can predict when I'm going to have cyano problems down to the day because of it.

Whenever there is precipitation, or a lot of snow melt, I end up with algae problems within 3 days. Spring melt = fluctuating diatom outbreaks (high silicate mountain run-off), summer storms and mid winter chinooks = cyano flare ups (agricultural run-off).

not saying that's what happened there, but tap water is pretty inconsistent.
