UPDATE: Alrighty! Here's an update on the Turf Starter I picked up from AlgaeNator.
After a week or so, the Starter Sheet I mounted at the top of my horizontal screen has really started growing. While not as fast as some people's screens have lit off I have to say I am very pleased. Remember I have not had ANY hair algae ever show it's face on my screen In just about a year of trying. So now the small spots that were originally on the screen are now covering a large area and spreading onto the usual Ice Plant turf I've had going. It also shows lots of oxygen evolution bubbles when the water is flowing across it.
I'm very happy with the growth I'm seeing.
Next I have to clean it which is always a little scary when one's finally gotten something going after a long struggle.
Thanks again AlgaeNator for sending me a test strip!
Though I don't expect any great change in my nitrate level yet I will test it in a few days and report.
