Cyano/red slime algae maybe under control. I did a 10% water change tonite. I used the turkey baster technique and the cyano floated right off and I suctioned it out. My astrea were picking on it, so, at least I have found a way to keep it under control. I readjusted my pumps as below.
Nano Cube Mod Change and Macro Note
Well..sometimes you have to learn that experience is the best teacher. I had placed a smaller pump in the third compartment to increase flow. Some people had said that the 3rd chamber would'nt handle it. Well..they were right. The water level was dropping too low and the heater was becoming exposed. Also, I was using a Maxijet 400, much lower flow. And...I got cyano. So...went back to the drawing board. I pulled the Maxijet 400 (106 gph) pump out and switched back in the stock pump (295 gph). I modified the outflow tubing and used softer tubing where it goes over the chamber walls. I placed my pump in chamber one at the bottom and put my media above it. BIG DIFFERENCE IN FLOW and all levels are excellent. Now I have an excellent clockwise water movement. My other reason for doing this is my first corals will arrive tomorrow (with trepidations). Here's the pic of the changed mod:
Interesting note on the macro (halimeda)...it continues to be very green in the back refugium. However, the small amounts I put in the main tank are turning white. Go figure..now I'm back to thinking that maybe the quartz submersible IS working. SH
