Water Systems for
Designed to fit under a 7 wide fish rack, this high quality water system can supply one or two 120 tank fish racks**... system includes:
1. Pre-filter* - water from each
rack flows through parallel bag filters and into the bio-chamber.
2. Bio-filter - venturi air enriched
water keeps the bio-media moving to provide very efficient chemical
filtration. Over 110% of the water is chemically filtered before
it is returned to the tanks.
3. Final-filter * - parallel bag
filters remove fines to enhance UV kill in next stage.
4. 1000 Watt Heater - maintains
temperature of water when set within 10 degrees of ambient.
5. Dual High Output 50 watt UV-sterilizer - provides over 200K MWS at flow rate of 5 Gal./Min. For a single
rack (120 tanks) or 100KMWS at a flow rate of 10 Gal/Min. for
two racks (240 tanks). Kill power listed is at end of bulb
6. Circulating Pump - energy
efficient, magnetic drive circulating pump provides up to 25 Gal/Min
and is salt water compatible - no metals in contact with water.
7. Air Pump - is a linear piston
type... known for quiet, energy efficient, oil free, and maintenance
free operation ... 8 years of continuous operation is not uncommon.
8. Automatic Fill Valve - keeps
water at proper operating level.
9. Low Water Sensor - shuts off
circulating pump, UV, and Heater upon low water condition. It
automatically resets when water fills above upper level switch.
10. Overflow - safely dumps water
into drain during high water condition or for changeout.
11. Blocked Filter Indicator - lights
when any of the parallel filter pairs block... overflow bypass
provided to allow continued operation.

* The bag filters for the input and final filters
are available in user selectable micron ratings. Typical ratings
available include: 100, 50, 25, 10, 5, microns. A typical
installation would use 50-100 micron for the input filter. Thoren
Aquatics recommends keeping spare sets of each filter group on
hand for change out. The dirty filters would be removed for cleaning
and the clean set put in place. Normally the input filter pair
would be cleaned every few days, and the final filter every few
weeks. The length of time time system operates between filter
changes is dependent von operating conditions, such as the number
of fish being maintained, type type of fish food, water makeup,
and water temperature.
** Larger water and air pumps are required for
two rack operation... smaller pumps provide greater efficiency
for single rack use.
