Since you are planning for a future tank upgrade, I'd choose the 9010 because it has a more powerful pump than the 9005. Since the 9010 includes the sump kit, the cost difference is small.

Has anyone had a chance to perform the same comparative test with Warner Marine's PHOSaR HC? This granular GFO is denser than its competitors and should be more durable.

Yes, my lighting is only T5 now but there is nothing wrong with a T5/MH combo. The MH produces beautiful "glitter lines" or shimmer if that is a consideration.

I replaced the MH/T5 combo because...

The thread starter wanted carbon media that produces less dust and such media was suggested to him. If there are tests showing high levels of phosphate from the suggested media, do let us know.

The squeaky wheel should get the oil. If controllers are more reliable than heater thermostats, then more will be gained through better operation, care and calibration of heater thermostats.
