would it be o.k. to put the fry in the basement pond? i never drained it and its stil being filtered. i will take out the 12 fish that are in it and put them outside. and cover the large barrel style prefilter with a nylon stocking and put a smaller pump feeding the filter. the aeration is still there too. and water parameters are still good to go. because they are more prone to ammonia i will put a zeolite basket under the return pipe. or maybe put a small pump in a zeolite fiiled bucket returning the water thru a hole and pipe in side,back in the pond? and put a screen over the top of bucket.
