I have decided to sell my Co2 system. Will be traveling oversees for a couple months later this year and don't think I will have a planted tank for quite a while. Everything is mint condition, in original boxes, and comes with original receipts. I had the control device custom made by Dupla in Germany to work on correct volts, etc. Everything might be under warrantee as well. This was used for about 6 months before I decided to break down my tank, too many family issues going on at once (ie. Marriage, wifes phd graduation, family visiting, etc). I could post it on Aquatic Plant Central, but you need 25 posts to list an ad, and I just filled up the tank with gas (refills cost 10.00 at AAA fire supply by Fremont bridge) so I could test and calibrate it before selling. After taxes and shipping I paid around 1200.00, and am asking 500.00, which is just a bit more than the individual controller, which can control PH to within 1/100% accuracy. Let me know if anyone is interested. ~sniff, miss you my fishy loving friends! - macker There are 5 seperate pieces: (446.00) Dupla PH Control Alpha: http://www.shopsolution.nl/shop/home.asp?shopid=seameuk&prodid=controlalpha (130.00) Dupla Co2 Set Delta200: http://www.shopsolution.nl/shop/home.asp?shopid=seameuk&prodid=co2setdelta (115.00) Dupla Co2 Magnetventil: http://www.shopsolution.nl/shop/home.asp?shopid=seameuk&prodid=magneet (150.00) PH Electrode: http://www.shopsolution.nl/shop/home.asp?shopid=seameuk&prodid=phelectrode (80.00) Luxfer 2.5# High pressure aluminum tank, filled.
