I keep Saltwater Reef tanks. I belong to several "Reefer" forums...(Don't Google it. You'll get the wrong idea.) Each one of those forums has a DIY section, where people can share ideas and plans for things that they make to help them in the hobby. There are a million ways to do things, everyone has a different way. Depending on your skill level, someone may have a way of doing something that fits your skill level. I don't really know where to put this, but this seemed to be the best place. Okay, Let's see them. My daughter just made a feed scoop out of a 1/2 gal milk jug. She said she would post pictures later.
