Cold saltwater aquarium building 2 – technique

Here´s a short description of the technique involved in setting up the 500 liter tank.

The main tank is 500 liters, from here the water is guided to a 250 liter sump through the overflow. From the sump the water is pumped to a 140 liter aquarium, which was my old freshwater stream aquarium, now functioning as a filter.

Skimmer: DYI “mean midget” rated for 1000-1500 liter, airflow approx 3000 l./h. with a Atman HP8000

Flow in main tank: 1 X 12.000 l./h, 1 X 6000 l./h and 1 X 2600 l./h – all Tunze –  the pumps are on timer, reversing the flow every 12 hours

Pump from sump: 2000 l./h Aqua-bee

Chiller: Resun 15R it is rated for a smaller aquarium, but with the thermoglass and insulation with styrofoam I hope it is enough. In addition I can ventilate the whole room by drawing in fresh cold air through a ventilation fan in the outer wall and there is a fan in the ceiling drawing out the hot air in the room through the roof.

Aquarium circulation

The three Tunze pumps on each side og the overflow. They alternate the flow every 12 hours.

My algae reactor, so fra running just for test. to the left the filter aquarium.

From the sump, the water is pumped to a 140 liter aquarium filled with live rock. Above the aqurium there is a 39 W LED. I hope most of the algae will grow the filterinstead of the main tank.

The sump with the two outlets from the main tank, running in to a filter bag. The filter is actualle maid for straining water from berries, but it is perfect  for filtrating larger particles. The mean midget skimmer is running af some extensive repairs
