Automatic water top-off

[justincgdick]

Anyone have any ideas for a cheap way to make an automatic water top-off system?

2L pop bottle upside down in the water. Ugly, but it works...

I have been thinking about the same thing too, but haven't found anything good...boy, aren't we lazy! It seems allot more complicated than just pouring the water in ourselves. Though, I see how it could be useful if you are dealing with allot of evap or aren't around for a while.

i'm going to be doing an open-top soon, so I'm going to need it too.

If you have a sump....and we usually don't in this hobby... you can set up a topoff system from a reservoir or tap. Alternatively, a guy in my club setup a system using a lawn sprinkler timer and an over flow to 'change' 5% of his water every day. That would keep your tank topped up. I will be visiting him on Saturday and will get the specifics if you like.

You could also check out some reef and marine sites, such as nano-reef.com or reefcentral.com. They have lots of different designs for top offs, some using air pumps and switches. I've got a similar problem in my 10gal reef tank, and i'm going for an old school design...a plastic jug on a stand with a hose out the bottom and a valve! Hey, it'll work, just won't look pretty!
