Hang in there bro.
If you cant get co2 going, cover the tank with blanket for three days absolutely no light. That'll kill the algae, then don't use fertz and run the lights a shorter period. Itll keep the plants alive, but not provide a suitable growing environment... for anything. Then you can go back to normal once your co2 is fixed.
Ps. Can you please take pics up close of your stand especially corners ect. Also, what kind of finish was done? I am trying to make one or have one made for that matter but without having the seams like when formica or something similar is used. Thanks in advance.
