I have seen some tank dividers on ebay and was wondering how these work?

Do you have to empty the tank and glue the slots in there or can you fit them in wet tanks?

Depends on the divider, I have one that just slots in the tank so no need to empty any photos of the one you have seen

I have only seen these on ebay:

Are these like yours Goldy?

If you look at the picture on the boxes id say the main sheet slots into runners each side of the tank, with some sort of hooking device at the top - better check with the seller though, don't take my word for it.

Yes they do Euryale see link as it explains how to install I got mine many years ago and it has a lip thing on the bottom that went into the gravel for support, think it did have some clips but I couldnt use them as my 4ft had glass lips around the top so just cut a grove into the actull plastic plate and it fitted easy enough

Thanks guys.

One of mine has the glass strips along the top too so I would have to modify the clips in some way.
