hey quick question, i have the same system without the extension but I still haven't used it. I was wondering, the jet spray that comes of the laser tube, do you point that at the bottom of the net cup or in the corner of the chamber?
Bro you should get into doing youtube journals it is alot better you get more of a personal perspective almost like being in your shoes let me know if your down.
i had that same thing happen to mine. i did a water change in my bubble system with extra nutes and took care of the problem. if i remeber right, it was a maganese problem.
