The price for AM 1000 is much higher then for Rhinox 5000.Can I make 30ppm CO2 with Rhinox 5000?Filitration is TetraTec EX 1200 on the surface and Hydor Koralia 2-3 inside the aquarium.GH is 5 and KH is 3-4 with RO.Light is 2x150w 8000K HQI 8 inch from surface.I have this difusor at home Editor Choice - Co2 Diffuser for aquarium tank - eBay (item 310121948760 end time Feb-17-09 20:00:00 PST) and he is working very good IMO.It look like Rhinox 5000 and he is very cheap.
