Hello guys, I'm just about ready to run my calcium reactor, just trying to find a place to fill up my CO2 tank. Anyways, I was wondering what you guys find the best way to monitor the pH of the effluent water. Is it best to get a pH probe and put it in a containter that catches the water coming out of the reactor or should I drill the calcium reactor and add a pH probe port on the lid? I was going more for the DIY probe port because I think it would look nicer but I couldn't find a good enough probe bulkhead, I had found one on premium aquatics but reading the reviews it says that it won't fit the neptune probes very well and that's what I'll be using. Any suggestions for that? Any help would be very appreaciated. Thanks.
