One question, If I was going to hard pipe my wet\dry filter system what do I use for the glue ? or should I use silicone instead, or do you know of A type of glue to use that will not poison the fish and not harm the bio growing in filter

If you talking about using schedule 40 PVC then just use regular PVC cement (and primer). If your tank is up and running already with livestock then you'll need to make sure that you do not run anything through the newly glued plumbing for 24 hours but beyond that, there are no worries.
