Ok I have horrible hair algee, brown algee, and NO CO2 but my plants are starting to pearl? At first I thought it was some random air bubble but nope. I thought that was only supposed to happen under optimum conditions? I have been waiting and waiting for my CO2 setup to get here and I missed the FedEx guy to day. I haven't even started to fertilize yet (again waiting for the package in the mail from BigAls). :-k
