Copper Fountain Question

[dimammy]

I have a copper fountain/spitter in the deeper end of my pool. The statue turns a greenish blue when pool water splashes onto it. I understand this to be normal oxidation for copper, however I wonder if this greenish/blue hue may be affecting my water color and/or creating some type of algae. I keep the chlorine level at the high end of the recommendation based on my cyanuric acid level. Still, I'm finding repeat episodes of what appears to be dead algae on pool floor even though my combined chlorine with drop test reads zero?

Generally speaking, TFP doesn't really like copper in pools or pool water chemistry.

That said the fountain is not the source of algae blooms.......copper is an algaecide

When was the last time you did a Overnight Chlorine Loss Test?

When was the last time you did a Overnight Chlorine Loss Test?

I have been testing my chlorine every morning and it's dropping only about .5 (from 8.5 to an 8). Then I add recommended extra to bring it back up. All this being done with drop test, not test strips.

If the pool is clear, 0 CC's, and passes the OCLT then the dead algae is just normal sanitation and the chlorine doing its job killing what gets into the pool.
