GIGGETY-GIGGETY!!
this is a tutorial on my converting an old terapond filter to a basic skippy or koiguy style upflow filter. i used this on the basement pond and the 250 gallon pool i had fry and fingerlings in..but if youve got a small preformed pond and this filter or one like it. it will enable you to put it pond side as a waterfall. or if you have one laying around and want to put it to use......i used this with a 425 gph pump..trouble free, i use a tetrapond prefilter before the pump so no negligable amount of waste actually makes it to the filter.( if using with fry slide a nylon stocking over the prefilter to avoid any fry getting sucked in)
o.k now the work... first i put an1&1/2" elbow in for the output (in what would normally be the input). the elbow is aimed up to increase the volume in the filter. mine is adapted down to a 1&1/4" hose nipple so it can accept a 1&1/4" peice of hose if so desired. you could easily keep it 1&1/2" pipe or 2" if you like. but for 425 gph or less this works. ( i would go with the larger if you dont use a prefilter)
i took a peice of black diamond landscape border and ziptied a cut to fit peice of hardware fencing to it as the bottom grate ( cut a center hole for the down pipe). i cut the landscape border to fit the bottom of the canister..minus a section to fit around the bottom original output. just make a screwcap assembly for it for emptying and flushing the filter. or plug it.
on top of that theres 2 layers of blue furnace filter pads like i use in my other filters. with a center hole cut for the down pipe.
this is where you put your bio media..i used the original biosphers and cut up irrigation tubing...
when thats full.. use the original foam pad and activated cabon pad on top of the media.
i dont know that its neccessary but i also added a top grate cut to fit around the elbow.
i cut the end off the long L shaped pipe that originally goes on the original bottom output. thats now plugged or capped. use the long end, it already screws on to the inlet hose nipple. this is your downflow pipe. drill a hole thru the center of the lid and assmble the downpipe inlet assembly thru the lid.
