I'm pretty sure I only tightened these by hand, but I seemed to crack two out of three. I admit I do have some heavy auto mechanic hands. Was it the sealant maybe? It is still gooey and it didn't dry hard. Also, does anyone know for sure is the sealant aquarium safe? I couldn't find anything else to use at the local hardware store.
I kept breaking it apart on purpose to show the cracks but at first I didn't even notice them until I ran with water. I thought it was the seal and took me a bit to figure out they were cracked.
