The small chamber is a freshwater reservoir, and the large is the actual sump.
The Glass plate between the two chambers, is 28 cm high.
The freshwater reservoir can thus hold app. 39 liter and the sump app. 95 liter.
In practice this it is not advisable to run the sump at full capacity, as there MUST be room for excess water from the tank, which will spill down to the sump in case of a power failure.
The pictures show the highest safe water level, which is 16 cm. (app. 54 liter).
A: Freshwater reservoir. Here resides an Aquaclear 50 powerhead (1), that pumps water over to the sump, when electricity from the controller (2) to the osmolator, a Deltec Aquastat 1000, is connected.
B: Sump. The sensor for the osmolator (3) reacts to falling levels, which is the result of vaporizing. There are two drains from the tank, a main drain that reaches below the surface in the sump, and is equipped with a regulating valve (4) and a safety drain, which ends over the surface, thereby giving off an audible warning if it is active. The water is pumped back to the tank by a Tunze Ph 3000 powerhead (5) via the thin pipe (6). The Skimmer (7) is a Tunze DOC 9210.
The sump has been modified
The bucket (1) has no other purpose, than it is the one I use for filling the freshwater reservoir. An ATB 2`nd edition cone skimmer, with a silenced powerhead (2), has replaced the original Tunze skimmer, which had a defect motor, and gave off an unreasonable amount of noise. The black bags (3) are nylon stockings, which has been mounted on the drains to catch particles from the water. They are cleaned once or twice a week, along with the skimmer cup. A small powerhead (4) keeps the surface in the sump moving.
