We had the same problem with sedimentation, now we only use the whitlock vibert box directly zip-tied standing on a cinder-block so it escapes the heavy bottom sediment, and with some gravel about 30mm size in biggest compartment so the fry can lay comfortable after hatch. went from 1% to 95% survival rating.
