New Configuration

	Glass Tank Tank size is 142cm x 42cm x 76cm, accessable volume is 360 liter. The overflow box is placed on left back side of the tank, it is quite big 20cm x 20cm, because I need to open three big holes at the bottom of the overflow box, first one for 30mm PVC, it is designed for main overflow pipe, second one for 25mm PVC, it is designed for backup overflow purpose in case the main overflow pipe is failed. Third one for 20mm PVC, it is designed for water return, with this internal water return pipe, no external hose is needed in this system.
	Main return pump is Iwaki MD-55R It is strong enough for me to make four water outlets and one rainbar inside the tank. My original plan is use 3/4" LocLine for the water outlet, but I found that it may be too big for me, so I have changed to use 1/2", but they are compatible one, not LocLine.
	Iwasaki 150W 6500K bulbs and 55W Actinic PC Two Iwasaki EYE Color Arc MT150D 6500K MH Bulbs cooperate with Two 55w actinic Power Compact Bulbs. All the bulbs are light up by Iwasaki Electronic Ballasts. All the bulbs are mounted on the doors of the tank cover, it keeps around 10 inches between of the water surface. Four 2" fans used to cooling the lamps
	CPR SR4 Skimmer Very calm but very efficiency.
	Kent Float Valve Connected direct to the RO filter replace top off water automatically.
	Korallin C1501 Calcium Reactor Non-stop supplying Calcium Bicarbonate to the tank. Maintain Calcium level at the same time stablilize pH. I think it is the best Calcium Reactor in the world.
	Seaswirl Wavemaker Connected one of the main pump outlet, blowing oscillate left and right slowly.
	IKS Aquastar Midi Computer and Dosing Pump Very useful tools to maintain your aquarium. This computer does the following action to my tank. 1. Dose kalkwasser between 20:00 to 09:00 2.5ml per minute 2. Controls two Maxj-Jet power head to simulate Hi/Lo tide wave for every 30 sec. with ramdom factors. 3. Controls on/off of MH lighting and Actinic PC lighting 4. Controls Chiller start at 26.8C and stop at 26.6C 5. Controls Heater start at 26.4C and stop at 26.6C 6. Monitor pH set alarm when lower than 8.1 or higher than 8.4. Kalkwasser will be add when lower than 8.05 7. Temperature alarm when lower than 26C (heater failure) and higher than 27C (chiller failure) 8. Data directly transfers to desktop computer and send to Internet for very 15 minutes.
	Bioplast CO2 Kit and Kalkwasser Reservoir CO2 is controlled by a magnetic valve and timer to add CO2 to the Calcium Reactor from 08:00 to 19:00 There is a power head inside the Kalkwasser Reservoir started at 18:00 to 19:00 to stir the Kalkwasser, then one hour rest before added to the sump. No milky Kalkwasser will be added. Fresh RO water will continuely supply to the reservoir by a float valve.
	Teco RA680 Chiller Wonderful chiller, high efficiency, silence and low cost. Fully handle my 350L tannk with 2 150W MH lamps when room temperature is 33C.
