Thanks again folks!
Just spent a couple hours on tank maintenance...
Put a clean filter sock in the cabinet sump - washed the dirty one
Replaced the 3 month old Chemi-Pure Elite in the reactor in the sump
Soaked the Tunze ATO optical sensor in vinegar to remove Ca buildup. The sensor had been acting up lately (not "seeing" the water level at all times). After an hour soak in vinegar the sensor is clean, and the ATO is working like new again.
Replaced my 17 month old metal halide - trying a 14k AquaMaxx this time, but won't see the result of a new bulb till the mh switches on later. Washed the glass cover under the mh lamp, and rinsed the T5 lenses.
Pulled out the 2+ year old Stealth heater that quit working and inserted the new Stealth in the heater chamber (the new one had been hanging in the old skimmer chamber).
While I had the Orbit hood off I did some cleanup of the LifeReef siphon and back of the RSM. With a raised hood I get some algae growth back there.
Replaced my older version Euro-Reef (now Reef Dynamics) sump skimmer with the new version that goma (Greg) recently got from Robbert & Todd. I had the 2 pumps already so Robbert just made me the new skimmer body. Here's the startup:
This beast is sooooooooo easy to control versus the previous version. Just a little twist of the air adjustment tube (on the right) controls the foam level. Major improvement in ease of adjustment!
