I didn't know algae can be a problem for orchids. Looks like I need to
research more on that one.

I like to use rainwater to water my orchids but it's clear. With
yours you might have an algae problem or a really good source of
nutrients, after all we all know tap water contains chlorine which can
be harmful to plants. That's why they say to leave a gallon jar setting
out to get rid of it before you water your plants. Burr
