Well I bought one...

It will work out ok, because I have wax paper double thick on the back of my tank now. Tons of sun, even raises the tank temp several degrees.
Update:
Disaster... This is the moment all the planted books talk about, when you think your going to lose it.
My Nitrite level just spiked. Hadn't measured it in a few days and bam its now at 5ppm. I was hoping this was a mistake, did another test same result.
After several huge water changes throughout the day and a filter squeeze (needed to do this into my quarantine tank anyway, so it worked out) Nitrite is now reading around 1-2ppm. Went to find something to use to detoxify the nitrite, saw Amquel+ or whatever it is and didn't think it was right for me as it warned about oxygen and other issues. Got home read the forum and everyone suggests it! LOL

Added 1tsp of aquarium salt, way less than the dosage on package as per walstad and others recommendations, as it should detoxify the nitrite while I work this out.
Between this and the algae, I've got a battle on my hands. Well I just can't wait for things to finally calm down so my glowlights can make the move and I can start enjoying el natural maintenance.
