So I have a 150g tall, reef ready, dual overflow tank. I started filling it today and as the water rose and began to flow through weirs, I started to have a slight trickling into the sump from the drains AND returns BUT the overflows were only half filled... the only thing I can think of is water is slowly getting past the standpipes where they press into the bulkheads. Has this ever happened to any of you? And advice? I tried pushing them down a little harder but its still occurring...
