do you have sponge inside the reactor? this helped my reactor diffuse the co2 much better. are you using spray bar? how is it positioned? not sure whats going on in your tank, normally with so much co2 and while using reactor you should see the fish gasping within first hour. what kind of lighting you using? i think we will need more info about your tank and maybe then we will figure out why you have co2 issue. i know your main question was regarding the bps, but i think we should consider the proper co2 diffusion as well.
i looked at your photo bucket pics and those plants aren't looking so good, you don't have enough plant to begin with, i don't know who is using all that co2 you are diffusing in your tank when there is hardly any plant in there.
I have a spray bar vertically along the back. This is the one that is feeding co2 in to the tank. I also have a spray bar horizontally along the top for water agitation. I'm looking in to getting more plants but bought this first batch to see how things would go. I was out of town for a week while my cousin watched the house sadly the co2 wasn't on during that time thus the outcome. I'll get a sponge inside the reactor though.
