I am using several older all glass tanks as a staggered series of sumps. The bulkheads I am currently using are the standard (for All Glass at least) threaded bulkheads.
My problem is that nothing locally available seems to actually fit onto the threading of these bulkheads and their external threading. Does anybody know of any fittings (maybe an online source?????) that will thread onto these things??>????:tongue:
