I just got the regulator made by aquariumplants.com and the CO2 Reactor 200 with Rio 50 pump.

I have a 90 gallon, 48x18x24. I run A Filstar XP3 on each side with the spraybar at the top pointed up and a bit toward the front of the tank. I get a nice ripple effect. Also, I have hydor inline heaters on both returns of the filters.

I have the reactor on the left end of the tank about 1 inch above the substrate. The CO2 is high enough to lower my PH almost a full point to 6.4. My fish arent stressed, but I still have my staghorn of course.

My question is, with no other pumps and with the spray bars at the top... am I getting the best bang on the CO2 delivery?

It has only been running for 3 days so I am unsure of the effect so far. My CO2 runs 11 hours and is on a timer to go off and on with my lights.

Thanks in advance.
