I'm looking at the possibility of using a 4 ft tank for breeding a couple of different species of fish. I am thinging of how i can make a divider effecrively making 2x 2 ft tanks. I was thinking i would like to make it out so as it could be removed or installed once the tank has water in. My idea using plexi-glass or coloured plastic incorporating some routered mopani wood at the bottom as a stand and some kind of clip arrangement on the sides and at the top. Planning to use holes of around 10mm diameter to increase flow as much as possible. I know i need to use plastics that are ok for aquarium use and also plan to soak in with a carbon filter for a few days to draw out any nasties just to make sure.

Has anyone ever made something similar? been finding it hard to see any plastic grating or perf that states its safe for food use or aquarium use ?

I know some of you are going to think I'm working with this guy because I've posted several links to his stuff. I'm not though. This is just good stuff.

I use these as tank dividers in some of my larger tanks. Easy to use, easy to remove, adds to filtration if you have water movement through it. It will eat up about 2 inches of space.

Poret Foam

there are several kits you can buy to do this. Some of them use mesh, others plastic. One thing to consider is that if you use a solid plastic sheet then youwill need to have a filter for both sides. Thats why i would go for either a mesh or at least partially mesh barrier, so that the filtered water can flow through and get the whole tank

that link looks really good! I reckon the tank divider filter would be an awesome idea as it would add O2 as well as divide and filter...winner all round

what about plain old egg crate ? or lexan drilled with 10mm holes ?

For tank dividers we used either plastic canvas, used in crafting such as cross stitch and in the market costs around a quid a sheet (approx A4 size), or, for larger sizes we used some thin perspex cut to size with small holes burnt/drilled into them. This way you control the size and number required.

To support/hold in place we used plastic spines which can be found at your local office suppliers (we used Wilkinsons).

You do need the tank to be empty initially to set the spines to the glass using aquarium sealant, but you can set them at a number of different places so that your tank can be split into different sized sections. We used 3 spines per split, one on the bottom, and one each side. But once installed that's it. You can add and removed the dividers as you need to

Hope that helps.

ya know what they say .....

Necessity is the mother of all invention

I just use my own invention- 4X"rigid raisers"( the type you use for a home irrigation system to lift the sprinkler heads away), 4X 90degree (elbow) joints and a linen/washing bag with holes about 2-3 mm.
Simply cut the raisers to fit your tank add the elbow joints ( you now have a frame) and then stretch the bag on ,
too easy.
