Total Clean

We have developed a set of instructions to clean the recirculation system. Student tested the instructions today.
Full Clean and Maintenance.
· Turn off all Shut Off Valves from Tanks 1-5
· Pump will drain the sump storing additional water in all Tanks. *Be careful that Tanks do not overflow.
· When water falls below the ‘Sump to Pump’ outlet turn pump off. Do not run pump dry.
· Siphon fish faeces and excess food from the bottom of Tanks 1-5 to a bucket/s. Use this water to water Chrysanthemums (good nutrient value for plants).
· Remove the Riser from Tank 1 (large Trout) and use the hose spray with town water to completely rinse and clean riser. * Be careful to not spill contents of Riser when taking it out of tank. Rub and remove any algae from the Riser.
· Use the Riser from Tank 1 to replace the Riser in Tank 2 (small fingerling Silver Perch) so as not to allow fingerlings to enter drain pipe. * Be careful to not spill contents of Riser when taking it out of tank.
· Use the hose spray with town water to completely rinse and clean riser. Replace Riser in Tank 1
· Remove the Riser from Tank 3, then Tank 4, then Tank 5 and use the hose spray with town water to completely rinse and clean risers. * Be careful to not spill contents of Riser when taking it out of Tank. Rub and remove any algae from the Riser.
· Turn Off the Sump to Pump valve
· Turn the handle on the filter to Close. This will prevent the filter water emptying from the Filter Basket.
· Remove the screw lid from the Filter Basket and empty and wash the basket with hose spray and town water. Replace basket after checking ‘O’ ring.
· Lay the pool filter hose across floor from Sump to outside roller door and down the side of the ARC.
· Remove Sump Drain Cap and balance pool hose in mouse of Sump Drain.
· Open the Sump Drain Valve and drain sump.
· Use town water and hose spray to ensure all excess food, faeces etc. is removed from Sump through the pool hose.
· Close Sump Drain Valve, replace cap.
· Begin to fill Sump with Rainwater Tank Water- will take approx 15-20 mins.
· Open all Tank Shut-Off Valves. This will return excess tank water to Sump.
· Open Sump to Pump Valve
· Turn handle on Filter to Backwash. When sump has at least 6 metal cage divisions start pump.
· Watch filter bulb to determine when backwashed water turns clear. Approx 1 minute?
· Turn Off pump
· Turn handle on Filter to Rinse. Run for approx. 10 seconds. Turn pump off.
· Turn handle to Filter. Turn pump on. You will need to turn pump off if sump runs dry. Continue filling Sump with Rainwater.
· Water level in Sump should balance out to 4 metal cage divisions.
· Do not leave until balance is achieved and sustained.
