The system has been up and running now for about 3 days. Im sticking to this final layout which includes just one check valve between the diffusor and the buble canisters. The check valve that came with the diffusor is prety good I found it did not place too much resistance compared to the ones I originaly had on the system. I might order anotherone from aquarium guys and try out placing two of them on the canisters like I did when I first set up the system.
On saturday I emptied out the original canister and started two completely new ones, using one refill package provided by redsea and one provided by Nutrafin. I noticed a difference in both the amount of time it took before they started producing and the quantity they are currently producing.. First of all I used the "sugar" provided in the Red Sea refill in both canisters, and used half of the baking soda provided by nutrafin in each canister. Then I put the different yeast into their own containers and set up the system.
Within hours the One with the (RedSea) yeast was already producing CO2 bubles. The (Nutrafin) canister took a little longer but after about 12 hours both were producing a constant stream of bubles.
The Redsea canister produces about 12 bubles per minutes.
Nutrafin canister produces 6 bubles per minute.
Ill post udates on my CO2 project later.

The system has been running perfectly now for alomost 2 months now. Ive noticed quite a difference in my plants. They are thriving now. what I have noticed is that my PH has risen from about 7.8 (tap water) to about 7.2 to 6.9. and its kind of hard to get it to stay constant between water changes and during the lifecycle of the cannisters (2 weeks) I end up with fluctuations in pH.

I've started using sugar, baking soda and yeast from the super market because its much less expensive. and yeilds CO2 within minutes of being mixed.

Your setup looks nice, and I have no doubts the plants love you for it

Yes, nice setup! You worked hard on it! Are your plants pearling by the end of the day?

A fluctuation from a pH of 6.9 - 7.2 is nothing to worry about. The solenoid on my pressurized canister turns on when the controller reads a pH of 7.2 and stops when the pH is 6.9, so my tank fluctuates between those pH readings all day.
