Sounds like a good sized tank for each section. I'm a definite fan of a large footprint. I cant help you with a recommendation for a tank builder in Adelaide unfortunately. I'm with Anthony in that as long as you use an appropriate micron mesh you should not have juveniles pass through but adults do occasionally cross dividers. One way to prevent that is to use a flat piece of glass to form a Tee on top of the dividers. Which should create a good enough obstacle for all but the most agile of shrimp.

Hello, What you have there is Hydrocotyle tripartita Japan . Its a lovely little plant. Cheers Saul

Some pictures of my backlines

They work like other air sponge filters, except they give the extra benefit of additional biological filtration. It will never replace a canister filter in efficiency and capacity to filter a tank. But small nano tanks can get away with them. Given a choice of a normal sponge filter and a Biospon filter for a nano tank, you would pick the Biospon any day for the extra biological filtration. But for any tank larger than a nano, canisters are still hard to beat. Like any air driven sponge filters, they clog quickly, at least a lot quicker than canisters. Which means more maintenance. If you like a tank that is free of clutter like cables, heaters, tubes, CO2 diffusers, etc, than adding a sponge filter of any sort is going to add to the clutter.
