C02 Setup

I have Full CO2 Setup, that I need some advise how to make it work well with my setup

90 Gallon
Heavly planted
2 x 54 watt T5 lights, have option to add 2 more bulbs, but they make it to bright

10 lbs CO2 Tank
Regulator with solenoid and bulber counter
CarbonDoser EXT5000
milwauke SMS 122 has it own power plug for CO2

I don't know how I should make this setup work to my advantage so I don't have to mess with it very much. Should I setup that if PH drops to low then CO2 shuts off? Any advise?

The point of a pH monitor is that it will tell the solenoid to shut off CO2 flow at a certain point. In order for this to be productive, you need to know at what point your CO2 level is acceptable. The easiest way to do this is with a drop checker with a 4dKH solution. With pH indicator mixed with 4dKH water, the solution turns green at about 30 ppm of CO2 in the water column. Past 30ppm, the solution starts turning yellow. Animals living in the tank will start to suffer at some point beyond 30ppm The pH drops depending on the decrease of CO2 content and degrees KH. When you hit a point that you're happy with, you set the monitor at that pH level. When the monitor detects a pH at that level, it shuts off the CO2.
