i have just bought a filter box from ebay as the one i built(water storage tank) when i did my pond last year just doesnt seem to be up to the job certainley doesnt meet the surface area rule to be honest any how what i want to know is , is there any reason why i cant bring the dirty water in into the bottom of the box filled with flocor (cut up pipe) then through the course medium and fine sponge and let the clean water out of the top of the box, i realise the sponges might want to float so i planned to hold it down with a plastic tray with holes and fill this tray with watercress and mint(and a brick or 2) to try and help keep nitrates down , can anyone see any obvious problems i might have, the box is 4 foot by 2 by 2 it will have a botttom drain so i can flush it out regularly , is it ok to run the dirty water straight onto the flocor ?
