Here is my set up. I know the stand is pretty ugly looking, but its rock solid. I also modded the recirculation tube that goes from the top of the main chamber to pump intake tube with a tee and a valve so I can release the excess co2 build-up without making a mess and get rid of the annoying pump drawing too much air or co2 noise. Well, the reactor is in the garage so it really doesn't matter if it was a bit loud. I am lucky that there is a drain right below my reactor and the chiller, so even if I make a mess or if there is any leakage, it would go right into the drain.
So far I love the reactor, easily setup with no leaks at all. My ph in the chamber is around 6.5-6.6 which is controlled by my apex. effluent is a steady drip with no breaks. I have monitored my ph in the display tank and it has been solid, minor swing from 8.05-8.20 during a 24 hour period. My tank is a pig when it comes to cal/alk intake, so hopefully it will be able to keep up.
