Thank you for the replies.

Reaper - If I did go the chlorinated water route, what would the water mix ratio be?

rhizome - The algae is on the grow media in two of the eight pots on this system. I covered the pots just last night as I noticed the algae but I did not know that algae can't grow in the dark. Good news then I guess. So tonight I will go back in and try to light proof all the pots as best as possible. Do you think that adding more grow rocks to cover the algae would help as well, seeing as I still have room to add rocks to each pot?

Thanks again.
