Carlson Surge or Borneman Flush Device

[zulu_principle]

I have several of the carlson type surge devices in my fishroom.

Pros

Cheap
Great Water Flow
Power is usually external, no PH in the water


Cons

Bubbles
Noise
Saltcreep
Bulbs need cleaning more often.

I am setting up a new tank this week and would not use anything but based on my warehouse tank enviornment, just not sure if I would use it in a tank which is not recessed into a wall.

My 2 cents
