works just fine for me. makes life very easy. if you have the time (or energy) you can get better pricing by shopping the components from different sources. Save a lot of money that way.
That is a sweet kit, Not sure on the pricing, being from Canada and all. I paid $150 for my regulator, $99 for my solinoid valve, $246 for my Pin Point controller (and love it). I have an in tank reactor which was $40 and am thinking of getting the inline , (less clutter in the tank). Conponent wise, it is a nice kit, the pin point was a little tricky to set the high and low settings and the manual isn't the best, If you need help when you get it let me know. I had a 5 lb tank and upgraded to a 10 lb tank, it barely fits in the cabinet but man I have my ph set at 6.6 and that tank has been at 900 for 4 months now. One more thing with that inline reactor you don't need a powerhead to drive it like the in tank one, it run right off the output line in your canister filter.
thinking of the pin point. Find a source for "calibration fluids" (they cost $2.50 US). That way you can recalibrate on a monthly (or quarterly, or weekly) frequency. Never hurts to keep it accurate. Every month (maybe 2) seems to work for me.
Here is a link to a photo showing a 75 gallon after 7 weeks of having a very, very similar system running. http://www.tropicalfishgallery.com/photo-gallery/displayimage.php?album=lastup&cat=10052&pos=0 . If you scroll to the 16th photo in that gallery you will see the difference just 6 weeks maks. Somewhere in the gallery is a photo showing pre CO2 system. It has made life easy. all I have had to do is mess with fertilizers and make minor CO2 adjustments to control the algae.
It's a good system but some of the items aren't necessary, but luxuries.
For pressurized CO2 this is what I would get.
Milwaukee regulator + co2 tubing from ebay - $80 shipped
External reactor Aquamedic 1000 $60 or make one yourself $20 if you have a canister filter. Glass diffusor, or sweetwater stone aquaticeco.com if no canister.
5-10 lb cylinder from welding supply or fire extinquisher shop $80-100
