Looking into CO2 injection...

I have not been in the hobby for a few years... I moved into my house about a year ago and I am just not getting around to setting up my 58gal freshwater tank. It’s a reef ready with a sump. Right now I am doing my fishless cycle and I am looking into getting some plants in the next couple of weeks. Along with the plants I have already looked into getting a 10lb CO2 tank, Milwaukee regulator, and pH Controller. I am also looking at getting an AquaMedic 500 - CO2 Reactor. I was wondering if I could place the reactor in the sump. The sump is a 20gal (high) tank with a 350w Pro Heat Titanium Heater in it right now. (I want to keep as much clutter out of the tank as possible). The tank maintains temp with the heater in the sump, and I was wondering if I would get the same effect with the C02 if I place the reactor right in front of the pump that is feeding the tank above...

Thank you for your time

You're prolly going to be better off placing the return of the reactor actually inside the tank. I used a w/d filter for a few years on my main planted tank, and it was a pain trying to keep the CO2 from degassing due to the nature of the trickle filter. I have recently replumbed the sucker with PVC, and now my industrial-sized CO2 reactor also serves as the main filter. Strange, but it works exceedingly well.

Using a w/d filter for a plant tank...it can be done tho, don't lose heart. You'll need to make sure that there is as little surface ripple as possible by moving your filter returns around. I also lowered my degassing by installing a standpipe in my overflow to bring up the water level in the overflow to just a couple of inches below the tank water level, and thereby decreasing the "waterfall" effect.

The Aquamedic 500 is a tricky lil' thing, as I recall. It requires an additional powerhead for current, and you'll get gunk buildup fast, so be sure and clean it every couple of weeks.
