A new pump from Pentair Aquatics

A few weeks ago on Saturday I installed a new pump in one of our animal tanks. It is Quiet One Aquarium Pump 3000 - 780 gph from Pentair Aquatics. It can directly connect to Lifegard Module Filter System. But I didn't do that. I didn't want to do the plumbing job for all the circuitry of the PVC pipes under the tank on weekend. I just used plastic tubes to put it in.



Little Giant pumps were originally installed when Paul purchased them in 1997. Since then we had been using them with no specific reason despite their frequent failures. I like this new one better. It's real quiet. It is waterproof. And it's cheap (~$60)! Little Giant pumps usually cost more than $200. I will switch from Little Giant to Quiet One for all tanks.

Pleurobranchaea

A monster came to our lab.


Pleurobranchaea californica.


Dr. Gillette said this is a super-Tritonia.
I gave it a piece of salt, but did not induce the escape swim.

Tank 080609

Tanks look great.
Slugs ate seapens well. No death reported over the weekend.

Tank D had no water in upper level, because the bypass valve was left open. The water condition was fine, though. I cleaned the upper level and adjusted the valve.

15 Tritonia in A, 15 Tritonia in B, ? Aplysia in C, and 5 Tritonia in E.

There was the temperature alert from Tank D this morning.
I went down to check it and found that the bottom floor where motor and cooling units are sitting was all wet. There must be some water leak from somewhere.

Tank D often has this this leakage problem. I could not found detect where it is. No cracks, no loose connection.

Today, I found it.
This tube pass water from the upper tank to the lower tank.

The nozzle of this connection was loose. It was spraying water on the acrylic board.




I must have hit the cover when I opened or closed this cover for cleaning. I cleaned them all three times this week.
