Hi, We have an inbuilt tank (100 x 55 x 40 - so about 215 litres). We'd like to do freshwater tropical. Be really grateful for some advice about what kit is the best kit to get and what would be good to stock it with. We live near Cruise Hill, site of several aquatic shops, so there is professional advice near us. But I'd quite like to go in prepared and able to have an intelligent conversation about things. Really grateful for some input! Thank you .
