You as well as many other folks gotta break out of the habit of thinking there is a pill to fix everything (ammo lock etc). The fix is PATIENCE! take your time do it right, don't be in a big hurry. In the shooting sports we got a saying
, if you understand it then this new saying should make sense"you cant miss fast enough"
think about it, if I try to go to fast when shooting targets I will get misses, sure I went really fast but at what cost? aquariums are no different....sure you can set them up and put fish in them really fast , but at what cost? just to kill fish quicker?"you can't kill fast enough"
