Las Vegas here, it was in the 80s last week. Oh joy, summer already, but then we got a "cold snap" that dropped into the 50s.
I battled blue-green algae and BBA when I lived in San Diego, and battled it again when I was staying with my sister in Vegas before moving into my own place. I found live plants helped out a lot to eradicate it. I do have a little algae in my filter right now, but none that I can find in my tank. I did traumatized my Christmas moss when I dismantled the floating ball and tied it the wood, but it promptly bounced back and took off like wildfire.
I was feeding my fish and shrimp their evening frozen meal (thawed in advance) the other night, and noticed that a tiny bit of marimo had attached itself to the mopani. It was an interesting discovery, and I've previously found marimo bits attached to the pad when I changed my filter media.
