I have a Amiracle wetdry filter that has a 1" hole drilled in it, or thats how they are made. How would I plug this up? I am using mag drive pumps so I dont need the hole. Thanks
Put a bulkhead in it (with threaded insides) and screw in a 50cent plug from home depot.
OR you could get a small piece of acrylic or glass and silicone the piece over the hole
